Can this extract password-protected ZIP files?

Not currently. The tool can read the archive's file listing, but if the entries themselves are encrypted (AES or the older ZipCrypto method), decompression requires the password and this tool doesn't prompt for one yet.

Is there a limit on ZIP file size?

No hard limit is built into the tool itself. Since extraction happens entirely in your browser's memory, very large archives (several GB) may be slow or hit your browser's memory ceiling, but there's no server-imposed cap.

Does this work with ZIP files from Mac, Windows, or Linux?

Yes. ZIP is a cross-platform standard, and JSZip reads the same format regardless of which operating system originally created the archive.

What happens to folders inside the ZIP?

The original folder structure is preserved in the file listing — nested folders show their full path, and downloading preserves that structure.

Can I extract just one file instead of the whole archive?

Yes, each file in the listing has its own download button, so you can pull out exactly the files you need without extracting everything.

Will this work with very large ZIP files, like several gigabytes?

It can, but performance depends entirely on your device's available RAM, since the whole archive is processed in browser memory rather than streamed from disk the way desktop unzip tools work.

Is my ZIP file uploaded anywhere during extraction?

No. JSZip runs entirely client-side — the file is read directly from your device into browser memory, processed, and never transmitted over the network.

What compression format does this support — just ZIP, or also RAR and 7Z?

This specific tool only reads ZIP archives (the .zip format). For RAR files, use the RAR to ZIP converter first; 7Z support is a separate tool.

Does extraction change or damage the original ZIP file?

No. The tool only reads the archive to generate copies of its contents — your original .zip file on disk is never modified.

Can I re-compress the extracted files into a new ZIP afterward?

Yes, use the Create ZIP tool to bundle any files — including ones you just extracted here — into a new archive.

What is Extract ZIP?

A ZIP file is a container — individual files compressed and bundled together with a small index (the "central directory") at the end listing every entry's name, size, and location inside the archive. This tool reads that index entirely in your browser using JSZip, a pure-JavaScript implementation of the ZIP format, then lets you inspect and download the contents without ever sending the archive anywhere.

Because extraction happens client-side, there's no upload wait and no size limit imposed by a server — the only ceiling is how much memory your browser has available to hold the decompressed files. This also means archives containing sensitive content (financial exports, private photos, confidential documents someone emailed you as a ZIP) never leave your device during extraction, which matters for anyone who's hesitant to hand an unknown ZIP file to a random web service.

The tool lists every file and folder inside the archive with its size, and lets you download entries individually or grab everything as a fresh, unpacked folder structure. Password-protected ZIPs aren't supported — JSZip can read the archive structure but can't decrypt AES- or ZipCrypto-protected entries without the password, which this tool doesn't currently prompt for.

Need to go the other way — bundle files INTO a zip? Use Create ZIP. Got a RAR file instead? RAR to ZIP converts it first.

How It Works

JSZip reads the ZIP file's central directory — a compact index at the end of the archive listing every contained file's name, compressed size, and offset — without needing to decompress anything up front. Each entry is only decompressed (using the DEFLATE algorithm, the standard ZIP compression method) when you actually choose to download it, which keeps the initial listing fast even for archives with hundreds of files.

How to Use
