Was File Compressor (Zip / Unzip) useful?
Qu’est-ce que File Compressor (Zip / Unzip) ?
Create a zip archive from a list of files, or extract a zip you already have. The zip is built and extracted locally in your browser — your files never leave your device.
Useful for bundling a few files to send over email, opening a zip you just received, or making a small archive before sharing. The privacy angle is the differentiator: most online zip tools upload your files to a server to do the work. This one does not.

No file-size limit (other than your browser)
Streaming zip — handles a 1 GB file as comfortably as a 1 KB file. The browser may slow down with very large files; use a real desktop tool for anything over a few hundred MB.
