Why Choose JustUnzip
Not all online archive extractors are created equal. Most upload your files to remote servers. JustUnzip is different - it's built from the ground up with privacy and convenience in mind.
The JustUnzip Difference
Most "free" online tools have hidden costs - your data. They upload your files to their servers, may keep copies, and often have daily limits or premium upsells. JustUnzip processes everything locally using WebAssembly. Your files literally never leave your device.

Frequently Asked Questions
Is JustUnzip really free? ▼
Yes, completely. There's no premium tier, no daily limits, no signup required, and no ads that interrupt your workflow. It's free because it doesn't cost us anything to run - your files stay on your device.
How can I verify files don't upload? ▼
Open your browser's Developer Tools (F12), go to the Network tab, and watch while you extract a file. You'll see no upload requests - just the initial page load. The extraction happens entirely locally.
What formats are supported? ▼
ZIP, RAR, 7z, TAR, GZIP, BZIP2, XZ, and many more. If libarchive can read it, JustUnzip can extract it. Check out our formats page for the full list.
