Create and extract ZIP files online
Bundle any number of files — or whole folders — into a single ZIP archive, or open a ZIP to download individual files from it. Everything is done by JSZip inside your browser, so even private documents stay on your device.
Which compression level should I use?
Level 6 is a good balance of speed and size. Level 9 squeezes out a few more percent but is slower. Level 0 just stores files without compressing them, which is fastest for already-compressed media like JPG or MP4.
