Best File Compression Software in 2026

File compression software shrinks, bundles, splits and encrypts files so they travel by email, sit on disks or reach a customer's desktop in one piece.

Our order favours independent developers, then weighs install effort, what Pro or maintenance tiers add, which formats can be written rather than only opened, and whether Windows, Mac or both are covered.

Vendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. How that works.

In short

What file compression software does

File compression software packs files into archives such as ZIP and 7z, extracts formats like RAR and ISO, and protects or splits the result with passwords and size limits.

How we ranked these

5 criteria, in order

Five tests decide the order: setup effort, real cost, how your data leaves, whether you can walk away, and who the file compression tool was built for. Vendors outside the best-known names fill places 1 to 3 when they exist, and the big brands rank from place 4. Our how we work page explains the choice of these five and why we give no mark out of ten.

#1 PeaZip

Open source archiver covering Windows, Linux and macOS with 200 formats

Ranked #1 of 12 in Best File Compression Software in 2026.

Free tierOpen sourcePublished pricingElsewhere

PeaZip suits a buyer who needs one archiver across a mixed fleet. The vendor lists Windows, Linux on x86_64 and x86 with ARM marked experimental, and macOS or BSD on Intel and Apple Silicon.

Encryption choices include AES, Twofish and Serpent, plus an optional password and keyfile pair and a built-in password manager. Version 11.4.0 is current, though the page gives no release date. Making RAR archives requires WinRAR, and ACE needs a separate plugin.

What stands out
  • LGPLv3 licence
  • 200+ formats
  • Twofish and Serpent
Where it costs you
  • Contact is a developer email alone, with no firm, state or street named.
  • RAR creation depends on WinRAR being installed, and ACE needs a separate plugin.
Right for

Mixed Windows, Linux and Mac teams wanting one open archiver with strong encryption options

Wrong for

Anyone who needs a named company or support contract

Not stated by the vendorFree for private and professional use; LGPLv3 open source licence

#2 7-Zip

Tiny Windows installer with LZMA2 compression and mostly LGPL code

Ranked #2 of 12 in Best File Compression Software in 2026.

Free tierPublished pricingElsewhere

Setup takes minutes because the x64 installer weighs 1.6 MB and the licence file says nothing needs paying. Packing covers 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIM, while a longer list including RAR, ISO, DMG, CAB, MSI, RPM and VHDX is open-only.

Version 26.05 is dated 21 October 2026. Its licence file mixes LGPL, BSD clauses and an unRAR-related restriction, which a compliance team should read before redistributing any of the code.

What stands out
  • LGPL code
  • LZMA2
  • 87 languages
Where it costs you
  • It runs on Windows only, so Mac and Linux staff need another tool.
  • RAR, DMG and ISO appear on its open-only list, with no creation.
Right for

Windows desktops where an administrator wants a small installer and no licence handling

Wrong for

Teams with macOS machines or anyone wanting vendor support

Not stated by the vendorFree to download and use, with no registration; mostly LGPL licensed code

#3 PowerArchiver

Perpetual-licence archiver from a US company, with Office add-ins

Ranked #3 of 12 in Best File Compression Software in 2026.

Published pricingNorth America

Prices run from the Business edition through Professional and Professional Toolbox to a per-seat Enterprise licence, with an Enterprise Unlimited site-wide deal starting at a four-figure sum.

All licences are perpetual, and the optional PA Select maintenance plan costs 25% a year or 50% for three years. Enterprise adds FIPS 140-2 and audit logging. A separate macOS edition covers Apple Silicon only, and contact is by email and phone, not a street address.

What stands out
  • Perpetual licence
  • Office add-ins
  • FIPS 140-2 audit
Where it costs you
  • The optional maintenance plan adds 25% a year to the licence cost.
  • Prices carry only a dollar sign with no named currency, and no street address is given.
Right for

Windows offices that want perpetual licences, audit logging and Outlook integration

Wrong for

Individuals who only open the occasional ZIP file

United StatesPerpetual licences by edition with a published price list; optional yearly maintenance; 30-day trial

#4 Bandizip

Bandisoft's Windows tool: zero-cost edition plus a paid Professional tier

Ranked #4 of 12 in Best File Compression Software in 2026.

Free tierPublished pricingElsewhere

The latest build is v7.47 from 13 October 2026, offered for 32-bit, x64 and ARM64 Windows, as a Microsoft Store app and as a portable version; macOS has its own page.

New archives use AES-256, and RAR, RAR5 and ZSTD can be extracted. The Professional upgrade adds Password Recovery, Image Preview in Archive and repair, but its cost cannot be read from the pages reviewed.

What stands out
  • Professional tier
  • AES-256
  • Portable version
Where it costs you
  • The Professional price, currency and billing model are not shown on the pages read.
  • Repair, password recovery and malware scanning of archives need the paid tier.
Right for

Windows users wanting portable or Store installs with optional repair and recovery tools

Wrong for

Buyers who must see the upgrade price before choosing

Not stated by the vendorFree edition, business use included; separate Professional licence with price not shown

#5 BetterZip

Mac archiver with Quick Look preview and a one-time purchase

Ranked #5 of 12 in Best File Compression Software in 2026.

Published pricingElsewhere

BetterZip 6 has one price and one tier, so costing it takes seconds: a one-time purchase, a 30-day money-back guarantee and a 30-day full-featured trial beforehand. Creation covers ZIP, DMG, TAR, TGZ, 7-Zip, XAR and ISO.

Finder integration, a Quick Look extension and AppleScript support suit automated workflows. Because the vendor lists no minimum macOS version or location, an IT team has to test compatibility itself before rolling it out.

What stands out
  • One-time price
  • Quick Look
  • AppleScript
Where it costs you
  • Making RAR archives depends on an external command-line utility.
  • The minimum macOS version and the country are not stated on the page.
Right for

Mac users who want a single purchase with archive preview and scripting

Wrong for

Windows or Linux users, or anyone avoiding paid utilities

Not stated by the vendorOne-time purchase at a published price, no subscription; 30-day trial and money-back guarantee

#6 Keka Archiver

Mac archiver offering 14 creation formats and optional donations

Ranked #6 of 12 in Best File Compression Software in 2026.

Pricing on requestElsewhere

The page describes a 34.4 MB download for v1.6.8 and links the Mac App Store, so installation involves no sales contact. Optional tips can be sent in BTC, ETH, SOL or PayPal, which means there is no licence price to budget.

Splitting is aimed at mail and server size limits. Because the page states no open-source licence and no country, a compliance team has to ask questions before standardising on it across managed Macs.

What stands out
  • 14 formats
  • Split archives
  • Tip jar
Where it costs you
  • ZIP archives get only Zip 2.0 encryption, while AES-256 applies to 7z.
  • No licence, country or address is stated, only a link to a GitHub repository.
Right for

Mac users who create 7z or split archives and accept donation-funded software

Wrong for

Organisations that require a stated licence and vendor location

Not stated by the vendorDownload offered without a stated cost; Mac App Store listing; optional tips

#7 The Unarchiver

Mac utility that opens dozens of current and legacy formats

Ranked #7 of 12 in Best File Compression Software in 2026.

Free tierPublished pricingElsewhere

Setup is a download from the site or the Mac App Store on macOS 10.13 or later, with older releases behind an old-versions link. The list of readable formats runs from CAB, MSI and NSIS installers to BIN images and split files, which suits staff opening whatever customers send.

Nothing on the page mentions creating archives, password protection or compression settings. No licence is stated, and the company named in the footer has no address on the page.

What stands out
  • Extraction focus
  • Legacy formats
  • MacPaw Way Ltd
Where it costs you
  • The page describes opening archives only, with no creation or encryption features.
  • The licence and the company location are not stated.
Right for

Support desks on Macs that open unusual archives received from customers

Wrong for

Anyone who needs to compress or password-protect outgoing files

Not stated by the vendorFree with no in-app purchases; Mac App Store or direct download

#8 WinRAR

German-made Windows archiver with a downloadable trial and shop licence

Ranked #8 of 12 in Best File Compression Software in 2026.

Pricing on requestEurope

WinRAR 7.23 describes itself as one utility to compress, encrypt, package and back up. The imprint gives win.rar GmbH at Marienstrasse 12, 10117 Berlin. Licence tiers and prices are absent from the vendor's page, since buying runs through a shop link, so volume buyers must check there.

The trial download is offered before purchase without a stated length. No cloud or hosted option appears on the pages read, which makes it an installed desktop program.

What stands out
  • win.rar GmbH
  • 40+ languages
  • Trial download
Where it costs you
  • Prices and licence tiers are not shown on the vendor's own pages.
  • The trial length is not stated, so an evaluation period cannot be planned.
Right for

Windows buyers who prefer a named German company and a purchased licence

Wrong for

Teams that need published prices before starting a trial

GermanyLicence bought through a linked shop; downloadable trial of unstated length

#9 NanaZip

7-Zip derivative adding the Windows 11 context menu and extra codecs

Ranked #9 of 12 in Best File Compression Software in 2026.

Pricing on requestElsewhere

Aimed at Windows 10 version 2004 and later or Windows Server 2022 and later, NanaZip ships for x86-64 and ARM64. Its codecs go beyond 7-Zip: Zstandard, Brotli, LZ4, LZ5, Fast-LZMA2 and Electron ASAR.

The README describes an open-source archiver built on 7-Zip, yet GitHub flags the licence as NOASSERTION, so reuse terms need legal reading. Credits go to M2-Team and contributors, so no single company is accountable for support.

What stands out
  • 7-Zip derivative
  • Zstandard
  • Brotli
Where it costs you
  • GitHub reports the licence as Other, so reuse terms are unclear.
  • Windows 10 build 19041 or later is required, which excludes older machines.
Right for

Windows 11 users who want 7-Zip foundations with Zstandard and Brotli support

Wrong for

Organisations that need a clear licence and an accountable vendor

Not stated by the vendorProject hosted on GitHub with no price listed; licence field reads Other

#10 Archiver

Apple Silicon Mac archiver with parallel extraction and file splitting

Ranked #10 of 12 in Best File Compression Software in 2026.

Pricing on requestElsewhere

A Buy Now button sits beside a Download button with no amounts, so budgeting starts with a visit to the vendor. Opening RAR, Zip and 7zip is supported along with many other formats; creating certain ones can require a plugin download.

Parallel extraction helps users with many downloads waiting, and splitting with checksums eases transfers that have size caps. The macOS 26 requirement is the strictest on this list and rules out fleets that have not upgraded.

What stands out
  • Apple Silicon
  • Parallel extraction
  • Split into parts
Where it costs you
  • It needs macOS 26 on Apple Silicon, so older Macs cannot run it.
  • Price, country and address are missing from the page.
Right for

Apple Silicon Mac users on the newest macOS who handle many archives

Wrong for

Mac fleets still running older macOS or Intel hardware

Not stated by the vendorPaid app sold through a Buy Now button; price not shown on the page

#11 Ashampoo ZIP

Windows ZIP tool that stays cheap until you need the Pro upgrade

Ranked #11 of 12 in Best File Compression Software in 2026.

Free tierPublished pricingElsewhere

The vendor's page ends at an Add to cart button without amounts, so the Pro step cannot be priced from it. Pro, according to the FAQ, adds self-extracting archives, cloud support, ZIP repair and deeper Microsoft Office integration, though the product text partly contradicts this, which is a reason to confirm before purchase.

Windows Explorer integration is included, but the supported Windows versions are not stated in text. Creation is mainly ZIP, which limits it for 7z-centred workflows.

What stands out
  • Explorer integration
  • Pro upgrade
  • Mainly ZIP
Where it costs you
  • The page text and the FAQ disagree about which features sit behind Pro.
  • No Pro price, Windows versions or country appear on the page.
Right for

Windows home or office users who mostly handle ZIP and occasional extraction

Wrong for

Teams standardising on 7z with volumes and repair included

Not stated by the vendorFree edition of the Windows tool; Pro upgrade price not shown on the page

#12 WinZip

Subscription suite bundling Courier, SafeShare and PDF tools with archiving

Ranked #12 of 12 in Best File Compression Software in 2026.

Pricing on requestElsewhere

Standard includes WinZip Standard, Courier and Ad Remover. Pro adds Secure Backup, SafeShare, Image Manager, Duplicate File Finder and a System Utilities Suite, and Ultimate adds WinZip PDF Pro. Numeric amounts are missing from the page text, which shows only a per-month figure including VAT, billed annually.

For a buyer who needs compression alone this is a bundle of unrelated tools, and the trial ends with blocked access. Enterprise adds volume licensing, an IT-controlled encryption recovery key and policy enforcement.

What stands out
  • Annual plans
  • Bundled apps
  • AES-256-GCM
Where it costs you
  • Prices are billed annually and the amounts are not in the page text.
  • Owner and country are unconfirmed because the imprint page returned an error.
Right for

Organisations wanting an Enterprise archiver with recovery keys and policy enforcement

Wrong for

Individuals who want only compression without bundled apps

Not stated by the vendorAnnual billing across three plans, amounts absent from the page text; enterprise quoted; 21-day trial

How to choose file compression software

File compression software packs files into archives such as ZIP and 7z, extracts formats like RAR and ISO, and protects or splits the result with passwords and size limits. What separates these products is rarely a feature. Work through the steps below.

  1. 01

    Check who publishes a price

    The split is 7 published against 5 quoted. If you want to compare numbers first, start with PeaZip, 7-Zip, PowerArchiver, Bandizip, BetterZip, The Unarchiver, Ashampoo ZIP.

  2. 02

    Decide how much the jurisdiction matters

    Headquarters range over 3 countries and 3 regions: Elsewhere 10, North America 1, Europe 1. Legal exposure follows the vendor, not only the data centre, so read the contracting entity before you sign.

  3. 03

    Consider whether you want the source

    1 of these are open source: PeaZip. Hosting one yourself trades a subscription for maintenance.

Windows archivers: 7-Zip, NanaZip and Ashampoo ZIP compared

Most Windows buyers can stop at 7-Zip, which costs nothing, ships a 1.6 MB installer and runs on x64, x86 and ARM64. NanaZip builds on the same base and adds Zstandard, Brotli and the Windows 11 context menu, but it needs Windows 10 build 19041 or later and shows its licence on GitHub only as Other.

Ashampoo ZIP has a free edition with Explorer integration, yet it creates archives mainly in ZIP and keeps volume splitting and repair for Pro. Decide whether the machines you manage are recent, whether you need formats beyond ZIP and 7z, and whether a compliance review will accept a derivative project with several credited contributors instead of one company.

  • Match every Windows version in your estate against the vendor's stated minimum
  • Read the licence text before redistributing or bundling the tool
  • Check the minimum Windows version and which features sit behind a paid tier

Mac archivers: Keka, The Unarchiver, BetterZip and Archiver

Mac buyers face four very different tools, and none of them is a drop-in replacement for another. The Unarchiver opens a long list of formats, from MDF and NSIS to StuffIt, at no cost, but its page mentions no creation. Keka creates 14 formats and extracts 33, with AES-256 for 7z and only Zip 2.0 for ZIP. BetterZip charges a single one-time price and adds Quick Look and AppleScript.

Archiver 5 demands macOS 26 and Apple Silicon. Match the tool to whether staff mostly open files they receive or build archives to send out, and test on the oldest macOS version you still support before choosing a standard, because the cheapest option is not always the one that runs on the oldest laptop in the office, and a mismatch is usually found only after rollout.

  • List the macOS versions and Intel or Apple Silicon models in your fleet
  • Decide whether staff create encrypted archives or only open received ones
  • Compare one-time, donation and unstated pricing before approving a purchase

Paying for WinRAR, WinZip or PowerArchiver

The three paid Windows names bill very differently. WinRAR shows no prices on its own pages, sends buyers to a shop link and offers a trial of unstated length. WinZip bills Standard, Pro and Ultimate annually, includes a 21-day trial and a 30-day money-back guarantee, and bundles apps such as Courier and SafeShare. PowerArchiver lists perpetual editions with optional maintenance at 25% a year.

Ask for the full cost over three years, including renewals and maintenance, then compare it with 7-Zip or the Bandizip free edition, which its FAQ allows in business use. A paid archiver has to justify itself with a feature you will use, such as audit logging, Outlook add-ins or encryption recovery keys, rather than with familiarity or brand recognition alone.

  • Request the total three-year cost including renewals and maintenance
  • Check which bundled apps you would actually use before paying for a higher plan
  • Test the trial on real archives before the evaluation period ends

Encryption and formats in PeaZip, Bandizip and 7-Zip

Encryption claims vary more than names suggest. 7-Zip and Bandizip both state AES-256, PeaZip adds Twofish, Serpent and a keyfile as a second factor, and WinZip Enterprise names AES-256-GCM with FIPS 140-3 compliancy. PowerArchiver Enterprise lists FIPS 140-2 and audit logging. Format coverage differs as much: 7-Zip and PeaZip open RAR but cannot create it, while Bandizip extracts over 40 formats including RAR5 and ZSTD.

Work out which formats your partners send, which ones you must produce, and whether a regulator requires a named cryptographic standard for archives leaving the building. Remember that the strongest encryption setting is of little use if the recipient cannot open the result with the tool they already have.

  • Write down the formats you must create, not only those you must open
  • Confirm the encryption method named by the vendor matches your policy
  • Check whether password recovery or repair is a paid extra

What goes wrong most often when buying file compression software

  • Buying a WinZip plan for compression alone and then paying every year for Courier, PDF Pro and other bundled apps nobody opens.
  • Assuming a free Windows archiver can write RAR files: 7-Zip and PeaZip open RAR, and PeaZip needs WinRAR installed to create it.
  • Mailing ZIP files protected with Keka's Zip 2.0 option when AES-256 is only offered for 7z archives.
  • Rolling Archiver 5 out across Macs without noticing that it needs macOS 26 and Apple Silicon.

What is the best file compression software in 2026?

PeaZip leads our ranking of 12. PeaZip is written by one named developer, Giorgio Tani, and runs on Windows, Linux and macOS or BSD, which few archivers on this list match.

It reads over 200 formats and offers a password plus keyfile option. The catch is the page: it names no company, country or postal address, and RAR files can be read but not created unless WinRAR is installed alongside.
