ZIP Extractor

About this tool

ZIP Extractor on UtilityKit opens a .zip archive in your browser, lists every file inside, and lets you download any single file with one click. There is no upload, no install, and no server hop — JSZip reads the archive locally, so your files stay on your device. Drop in an archive up to 200 MB; the tool walks the central directory, lists each entry with its uncompressed size, and shows the total payload at the top. Click the down-arrow next to any file to download just that one — useful when you only need a single asset out of a large archive without unpacking it all. A 'Download all' button re-emits the archive as a single download in case you want a copy of the original. Browser-only operation also means everything works offline once the page is cached, and the file structure inside the archive is never logged or stored anywhere.

Why use it

• Browser-Only: JSZip runs entirely in your browser; the archive never reaches a server.

• Selective Extraction: Pull out just one or two files without unpacking the whole archive on disk.

• Path & Size Preview: See every file's path and uncompressed size before deciding what to extract.

• No Install Needed: Works without 7-Zip, WinRAR, or any desktop ZIP tool.

• Up to 200 MB: Comfortable for development asset bundles, photo backups, and source archives.

• Free & Unlimited: No account, no email, no daily quota, no watermark on downloads.

How to use

1. Drop a .zip archive onto the dropzone, or click to choose one (up to 200 MB).
2. JSZip opens the archive locally and lists every file with its uncompressed size.
3. Use the file list to scan entries — paths, names, and sizes are shown for every file.
4. Click the down-arrow next to any file to download just that one without extracting the rest.
5. Click Download all to save a single bundle copy of the original archive if needed.
6. Drop another archive at any time — there is no rate limit and nothing is cached.

When it helps

• When you need one file out of a multi-megabyte deployment archive without expanding the rest.
• When inspecting an unfamiliar .zip to see what is inside before opening it elsewhere.
• When working on a Chromebook or restricted machine where installing an unzip tool is not allowed.
• When grabbing a single asset out of a large CMS theme or font bundle.
• When sharing your screen and you want a clean, GUI-driven way to browse a ZIP without command-line clutter.
• When you only have read access to a download but want to confirm its contents safely.

Examples

release-2026-05.zip (140 MB)

Just config/prod.env.json downloaded — the other 38 files stay in the archive.

theme-twentyfour.zip

File list shown with style.css, functions.php, and 22 other files — pick exactly the ones you need.

Tips

• Use this tool to peek inside a .docx, .xlsx, .epub, or .apk — they are all ZIP archives under the hood.
• If a file inside has a long path, the size shown next to it is the uncompressed size, not the on-disk compressed size.
• Need to bundle files instead? Use the ZIP Creator tool to go the other way.
• For password-protected archives, decrypt them once with 7-Zip on your desktop and re-zip without a password before using this tool.
• When extracting a single executable, double-check the file size matches the publisher's listed size — a mismatch can indicate corruption.
