Create ZIP
Drop your files — or a whole folder — and they come out as a single ZIP archive, ready to attach to an email or set aside. The files never leave your device.
Your file stays on your device: nothing is uploaded
How it works
The archive is built inside your browser, one file at a time, and not a byte is sent anywhere. If you drop a folder, its structure is kept: subfolders stay where they are, and two files with the same name in different folders stay two distinct files. With “Automatic”, each file is compressed only when it is worth it: photos, video, PDFs and Office documents are already compressed inside, so they are stored as they are — recompressing them would cost seconds of waiting to gain fractions of a percent. Text, CSV, JSON, XML and source code are genuinely compressed, and there the saving is large. If two files end up with the same name, the second is renamed and we say so: no file is ever overwritten silently.
Your files are never uploaded. Anywhere.
Not to a server of ours, not to a third party, never. When you pick a file it stays in your browser’s memory: it is read, processed and written back on your device, and you save the result yourself. There is no path that takes it elsewhere, because there is no server to send it to.
- Processed locallyFormats are handled by WebAssembly code running in your browser, not by a remote service.
- Nothing to upload, nothing to wait forOther services send your file to a server and then send it back to you. Here the file never leaves: there is no upload to wait for.
- No accountNo sign-up, no email, no daily limits to get around by paying.
- No files to deleteOthers promise to erase your files after an hour. We have nothing to erase: they never reached us.
