Unzip Files - Extract ZIP Archives Online
Open a ZIP archive in your browser, browse its contents, and download individual files or everything at once.
Extract ZIP archives without installing anything. Drop a .zip file to see every entry with its full path and uncompressed size, then download single files or the whole archive sequentially. The ZIP is parsed locally with JSZip, so it works offline and never touches a server.
ZIP is the default container for almost everything you download: source code exports, font packs, invoice batches, photo bundles, and software releases. Opening one usually means a desktop archiver, but on a locked-down work machine, a Chromebook, or a tablet that is not always an option. This tool reads the archive directly in the browser using JSZip, the same library that builds ZIP downloads across this site, so there is nothing to install and no upload step.
Drop a .zip file (or pick one from disk) and the central directory is parsed in milliseconds, even for archives holding thousands of entries. You get the archive name, a file and folder count, the total uncompressed size, and a scrollable listing where every entry shows its full path inside the archive and its expanded size. Each file has its own Download button, which is handy when you need one config file out of a 200 MB release archive without extracting the rest. Download all walks the file list sequentially, handing each file to the browser as an object URL.
Password-protected archives are detected and rejected with a clear message, since the ZIP encryption schemes (ZipCrypto and AES) are not supported by JSZip. Truncated or corrupt files fail with an explanation rather than a blank screen. Folders are listed for context but are not downloadable, because browsers save individual files, not directory trees.
- 1
Load the archive
Drag a .zip file onto the drop zone or click it to browse. The archive's table of contents is parsed locally in your browser.
- 2
Inspect the contents
Review the entry list: full path, uncompressed size, and folder markers, plus totals for the whole archive at the top.

Download what you need
Press Download next to a single file, or Download all to save every file in sequence. Allow multiple downloads if your browser asks.
Peek inside a download
Check what a release archive or code export contains before extracting anything to disk.
Pull one file from a big archive
Grab a single README, config file, or image out of a multi-hundred-megabyte ZIP without unpacking it all.
Restricted machines
Open ZIP attachments on a work laptop or Chromebook where installing 7-Zip or WinRAR is not allowed.
Verify an archive built elsewhere
Confirm a ZIP you generated in a script or CI job contains the expected paths and file sizes.
Is the ZIP file uploaded anywhere?
No. The archive is read with the FileReader API and parsed by JSZip inside your browser tab. Closing the tab discards everything; no server ever sees the file.
Can it open password-protected ZIP files?
No. JSZip cannot decrypt ZipCrypto or AES encrypted entries, so protected archives are detected and rejected with an error. Decrypt them first with a desktop tool such as 7-Zip.
How large an archive can it handle?
The whole ZIP is held in memory, so the practical ceiling depends on your device. Archives of a few hundred megabytes work fine on a typical laptop; multi-gigabyte files may exhaust browser memory.
Why does Download all save files one by one instead of a folder?
Browsers can only save individual files, not directory structures. The tool spaces downloads about a third of a second apart so the browser accepts each one; you may need to allow multiple downloads once.
What happens with a corrupt or truncated ZIP?
Parsing fails safely and you get an error explaining the archive could not be read. Nothing crashes, and you can immediately try another file.
