Open a ZIP and take just the files you need — on any device, with nothing installed and nothing uploaded.
One .zip archive · opened on your device, nothing is uploaded
No size limit · files are processed on your device and never uploaded · how it works
Runs in your browser. Files are never uploaded — you can go offline after the page loads.
How to use the Unzip Files
Drop a .zip file — the contents list instantly.
Download exactly the files you need, or all of them.
Done — nothing was installed and nothing was uploaded.
Easy to use
Drop files, pick options, download. Whole folders at once, no signup, no daily limit.
Best quality
The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.
Private & secure
Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.
For the places extraction software isn't
Phones, locked-down work machines, a friend's laptop: the situations where a ZIP arrives and nothing on the device will
open it. This page opens the archive in the browser itself — the file never leaves your device, and you can pull out a
single document without unpacking two hundred files onto the desktop.
Limits, honestly
Password-protected archives are not supported yet, and formats like RAR and 7z are different beasts — this tool speaks
ZIP, which covers the overwhelming majority of archives in the wild. Going the other way is
Create ZIP.
Frequently asked questions
Why unzip in a browser?
Phones, work machines without extraction rights, and one-off downloads: anywhere installing software is impossible or overkill. The archive opens instantly and you pull out only what you need.
Are password-protected ZIPs supported?
Not yet — encrypted archives need the password-aware format, which this tool does not implement. Everything unencrypted opens fine.
Is there a size limit?
No fixed limit; archives of hundreds of megabytes open fine. The ceiling is your device’s memory.
Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.
No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
No limits. No file-size cap, no queue, no watermark, no account.
Runs on your CPU. Batches use several cores in parallel; nothing is throttled.
