Frequently Asked Questions

Can I see contents without extracting?

Yes — the archive lists every file with sizes instantly. A 500 MB download reveals its 40 files before you commit disk space or trust.

Are password-protected ZIPs supported?

Standard ZipCrypto passwords work where supported; AES-256 archives may refuse — try the desktop 7-Zip for those. The tool says so upfront instead of failing mid-extract.

How large an archive opens?

Hundreds of megabytes parse fine locally; gigabyte archives can strain mobile browsers — extract those on desktop. File count matters more than bytes: 5,000 tiny files list slower than one big video.

Are my archives uploaded?

No — parsing and extraction run locally in your browser with fflate. Archive contents never leave your device.
