Why Extract Files in the Browser?
Most online unzip tools upload your archive to a remote server, which raises privacy and speed concerns for sensitive or large files. This tool runs entirely client-side — extraction happens in your browser tab using WebAssembly-accelerated JavaScript, so there is no wait for an upload and no risk of data leakage.
Tips for Extracting ZIP Archives
Check file sizes first
The list shows each file's uncompressed size before you download. This helps you decide which files to save without downloading everything.
Password-protected ZIPs
Encrypted ZIPs are not supported. You will need a native app like 7-Zip to enter the password and unlock those archives.
Large archives on mobile
Mobile browsers have tighter memory limits. For ZIPs over 200 MB on a phone, a desktop browser is more reliable.
After download
Downloads land in your browser's default downloads folder. Move or rename them immediately if you need to keep them organised.
Frequently Asked Questions
Are my files uploaded to a server?
No. All extraction runs locally in your browser. Your files never leave your device — there is no server involved at any point.
What ZIP formats are supported?
Standard ZIP archives using DEFLATE, Store, or ZIP64 entries. Password-protected ZIPs are not currently supported.
Can I extract individual files from a large ZIP?
Yes. After extraction, each file appears in the list with its own Download button, so you can save only the files you need.
What happens to directory entries?
Folder entries (paths ending in /) are skipped automatically. Only actual file contents appear in the results list.
Is there a file size limit?
No server-side limit — it depends only on your browser's available memory. Typical modern browsers can handle ZIP files up to 1–2 GB comfortably.
Can I open ZIP files on iOS or Android with this tool?
Yes. The tool works in any modern mobile browser. Tap to select the ZIP from your Files app and then tap Download on the files you want to save.
