Extract a ZIP file
Open a zip and pull files out — on your device, so passwords stay local.
Drop your file here
It is processed on your device — nothing is uploaded.
Opening a zip on your device
Drop in a zip and the contents come back out. A single file inside comes straight back as that file; several are repacked as one uncompressed archive, because a web page cannot write a folder to your disk.
The whole thing happens in your browser, so the archive is never uploaded.
Why that matters here specifically
Zip files are how people send documents in bulk — scans, statements, exported records, backups. An online extractor that uploads first has taken a copy of all of it. This one cannot, because there is no server involved.
Password-protected archives
These cannot be opened here, and the tool says so rather than failing vaguely. That is a limitation worth accepting: opening one would mean sending the password somewhere, which defeats the purpose entirely. Your operating system already handles encrypted zips — Windows, macOS and Linux all do it natively, without a network.
Formats
ZIP only. RAR and 7z use different, patent-encumbered algorithms with no practical browser implementation. A file named .zip that is really a RAR is reported rather than half-extracted, since uploads are identified by their contents rather than their extension.
A note on archives from strangers
Zip files are a standard malware delivery method, precisely because the contents are hidden until opened. Extracting here is safe — nothing is executed, and the browser cannot run what comes out — but be careful what you do with an extracted .exe, .scr or macro-enabled document afterwards.
Making one
Create ZIP goes the other way, also without uploading anything.
Common questions
Is my archive uploaded?
No. It is opened in your browser and nothing is transmitted.
Can it open password-protected zips?
No, and deliberately — that would mean sending us the password. Your operating system handles those natively.
Does it support RAR or 7z?
No. Those use different algorithms with no practical browser implementation.
Why do I get a zip back?
A web page cannot write a folder to disk. A single file comes back directly; several are repacked uncompressed.
Is it safe to extract an archive from a stranger?
Extracting is safe — nothing runs. Be careful with what comes out, especially executables and macro documents.
