About Files to ZIP

Combine any set of files into a single ZIP archive. Add as many files as you like and choose a compression level; we build the ZIP with fflate right in the page — ideal for packaging documents, images, or anything you need to send as one download.

Everything happens in your browser. None of your files are uploaded — the archive is created entirely on your device.
