Processed entirely in your browser. Never uploaded to a server.

This tool packs any files you drop in into a single compressed ZIP archive, all in this browser tab. Drop or select as many files as you like, remove any you don't want, set a name for the output file, then click Create ZIP.

How it works

Each file is read directly from disk and compressed with standard deflate compression, the same algorithm most ZIP tools use. Files that are already compressed (photos, PDFs, video) won't shrink much further, but text, code, and uncompressed documents typically come out noticeably smaller. Nothing is uploaded at any point — reading, compressing, and packaging all happen locally, and the resulting ZIP is handed straight back to you as a download.

FAQ

Is there a limit on how many files or how large a ZIP I can create?
No fixed count, and no artificial file-size limit. This is just packaging bytes together, so the real ceiling is your browser tab's available memory, not a number Kit-Bin picks. A few dozen ordinary files or a couple of large ones both work fine; hundreds of very large files at once may slow down or run out of memory on a phone.
Does this actually compress the files, or just pack them together?
It compresses. Unlike some of Kit-Bin's other tools that skip compression because their output is already a compressed format (PNG, JPG, PDF), this is a general-purpose "zip whatever I drop in" tool, and the files people drop here (documents, spreadsheets, code, text) are often genuinely compressible. So it runs standard deflate compression by default rather than just storing the raw bytes.
Are my files uploaded anywhere?
No. Every file is read and zipped directly in this browser tab. Nothing is sent to a server.
Can I zip a mix of file types together?
Yes. Any file type is accepted and they all go into the same archive — photos, PDFs, spreadsheets, whatever you drop in.
What happens if two files have the same name?
Kit-Bin keeps both. The second file is renamed with a "(2)" suffix so nothing gets silently overwritten inside the archive.
