About this tool

RAR & 7Z Extractor on UtilityKit is meant to open .rar and .7z archives in your browser with libarchive.js, a WebAssembly build of the libarchive library. As shipped, the page requests libarchive.js 1.3.0 from unpkg at dist/libarchive.js, a file that version of the package does not contain, so every archive stops with "Failed: CDN load failed for libarchive.js." No files are listed or extracted until this is fixed. The page itself has no upload step: it checks that the file is 100 MB or smaller and then only tries to load the script. Even once loading works, libarchive cannot decrypt password-protected RAR or 7z archives. Until then, open .zip files with the ZIP Extractor and .tar, .tar.gz or .tgz files with the TAR.GZ Extractor on this site, and use 7-Zip, WinRAR or The Unarchiver for .rar and .7z.

Why use it

  • No Upload Step: The page never sends your archive to a server; its only network request is for the libarchive.js script.

  • Size Check First: Archives over 100 MB are rejected with a clear message before any library is downloaded.

  • Honest Failure: When the extractor library cannot load, the page says so instead of showing an empty or partial file list.

  • Working Alternatives on This Site: ZIP and TAR.GZ archives open in your browser today with the dedicated ZIP Extractor and TAR.GZ Extractor.

How to use

  1. Drop a .rar, .7z, .zip, .tar, .tgz or .iso file onto the dropzone; files over 100 MB are rejected before anything loads.
  2. The page then tries to load libarchive.js 1.3.0 from unpkg, which currently fails with "Failed: CDN load failed for libarchive.js."
  3. Until that is fixed, open .zip archives with the ZIP Extractor and .tar, .tar.gz or .tgz archives with the TAR.GZ Extractor on this site.
  4. For .rar and .7z files, use 7-Zip, WinRAR, The Unarchiver or your operating system's built-in extractor.

When it helps

  • When you have a .zip, .tar, .tgz or .tar.gz archive — use the ZIP Extractor or TAR.GZ Extractor on this site, which work in the browser today.
  • When you have a .rar or .7z file — use 7-Zip, WinRAR or The Unarchiver, because this page cannot open archives at the moment.
  • When a .rar or .7z is password-protected — use a desktop extractor; libarchive cannot decrypt RAR or 7z encryption.

Examples

Trying a .7z today

Input
screenshots.7z (45 MB)
Expected result
Failed: CDN load failed for libarchive.js.

Oversized archive

Input
backup.rar (150 MB)
Expected result
File exceeds 100MB limit.

Tips

  • Use the ZIP Extractor for .zip, .jar, .epub or .docx files — it runs in your browser with JSZip.
  • Use the TAR.GZ Extractor for .tar, .tar.gz and .tgz archives.
  • For .rar and .7z, 7-Zip (Windows), The Unarchiver or Keka (macOS) and unar or p7zip (Linux) are free desktop options.
  • Use the ZIP Creator afterward to re-bundle files extracted on your desktop into a .zip for people without a 7z or RAR tool.

Frequently Asked Questions

Does this tool work right now?
No. The page asks unpkg for libarchive.js@1.3.0/dist/libarchive.js, which that package version does not include, so loading stops with "Failed: CDN load failed for libarchive.js." No archive type opens until the script path is fixed.
Are my files uploaded?
No. The page has no upload step. It only requests the libarchive.js script from unpkg; the archive itself is never sent anywhere.
What is the file size limit?
100 MB. Larger files are rejected with "File exceeds 100MB limit." before the page tries to load any library.
Does it support password-protected archives?
No. The page is written to prompt for a password when libarchive reports encrypted entries, but libarchive can only decrypt ZIP encryption, not encrypted RAR or 7z archives. Use 7-Zip or WinRAR for those.
Which formats does the picker accept?
.7z, .rar, .zip, .tar, .tgz, .tar.gz and .iso — formats libarchive can read. For .zip and .tar.gz archives today, use the ZIP Extractor or TAR.GZ Extractor on this site instead.
Is the tool free?
Yes — completely free, no signup, no email, no ads, and no daily limit.

Glossary

RAR
A proprietary archive format created by Eugene Roshal. Known for high compression ratios and built-in error recovery records. Currently in version 5.
7z
An open-source archive format originated by 7-Zip. Uses LZMA / LZMA2 compression and AES-256 encryption, often producing smaller archives than .zip.
Solid archive
A 7z option that compresses all files together as a single stream. Improves compression ratio but means you must decompress the whole archive to extract any single file.
libarchive
An open-source C library that reads and writes many archive formats. The WebAssembly port (libarchive.js) brings this support to the browser.
