Open ZIP files without installing software

ZIP is the most common way to bundle and compress files, but you don't always have an unzip program at hand — on a Chromebook, a work computer with locked-down software, a borrowed laptop or a phone. This online unzip tool opens ZIP archives directly in your browser, shows everything inside and lets you download just the files you need. Because the archive is processed on your device, nothing is uploaded and your files stay private.

Features

  • Opens standard ZIP archives created by Windows, macOS, Linux and most apps.
  • Browse the contents with folder paths and file sizes.
  • Download individual files — no need to extract everything.
  • Search within large archives to find a file quickly.
  • Skips macOS clutter such as __MACOSX folders and ._ resource files.
  • Private and fast — no uploads, no waiting for a server.
  • Works everywhere: Windows, Mac, Linux, ChromeOS, iPhone, iPad and Android.

When this is useful

  • Email attachments sent as ZIP files when you only need one document.
  • Downloaded assets such as fonts, icons, templates and themes.
  • Photo exports from cloud services that arrive as ZIP files.
  • Checking what's inside an archive before extracting it all on your computer.
  • Mobile devices where built-in ZIP support is limited or awkward.

About ZIP compression

A ZIP file stores one or more files, usually compressed with the Deflate algorithm. Text, documents, spreadsheets and code compress very well — often to a fraction of their original size. Photos, videos and music are already compressed, so zipping them saves little space but still bundles many files into one convenient download.

Safety tips

Archives from unknown sources can contain malware. Extracting a file in the browser doesn't run it, but be careful with programs (.exe, .msi, .app, .apk), scripts and Office documents with macros after you download them. Scan unexpected attachments with antivirus software before opening them.

Frequently asked questions

Is the ZIP file uploaded to a server?
No. The archive is opened and decompressed in your browser using JavaScript. Nothing is sent over the internet, which makes it safe for private documents and also fast, because there's no upload or download wait.
Can it open password-protected ZIP files?
Not yet. Encrypted ZIP files show an error message. Use a desktop tool such as 7-Zip, Windows Explorer or macOS Archive Utility to open them.
Does it support RAR, 7z or TAR files?
This tool opens standard ZIP archives (including .zip files created by Windows, macOS, Linux and most apps). RAR, 7z, TAR and GZ use different formats and aren't supported yet.
How large can the ZIP file be?
There's no fixed limit, but the whole archive is decompressed in your device's memory. Archives of a few hundred megabytes work on most computers. On phones, very large archives may fail because of memory limits.
Why are some files missing from the list?
Folder entries are shown as part of each file's path rather than separately, and hidden macOS resource files (the _MACOSX folder and files starting with .) are skipped because they aren't useful on other systems.
How do I unzip files on iPhone or Android?
Open this page in your mobile browser, tap Choose file and pick the ZIP file from Files or Downloads. Tap the download button next to a file to save it. No app is needed.
