Trust, clarity, and speed
100% Client-side
Files never touch a server. All compression happens in your browser via WebAssembly-grade zip.js.
Privacy by default
No accounts, no tracking, no upload queue. Your data stays on your device, period.
Preview before download
Preview files that your browser can render (images, audio, videos, .txt and .html) before downloading them.
Folders & nesting
Drop single files or entire directories and view the folder structure in your archive.
No file limits
As many files as your browser can hold. No daily caps, no premium tier, no signup.
Instant & offline
Because files are compressed locally, there is no upload delay. Compression finishes as fast as your device can process it.
Works everywhere
Any modern browser, any OS — desktop or mobile. No install, no plugins, no app.
Open format
Standard .zip output that opens in Windows, macOS, Linux, iOS, and Android out of the box.
Common questions, answered clearly
However, if you email the ZIP file you made or save it to Dropbox, that ZIP file is sent to our server and saved there for a short time.
