Create ZIP archive files in your browser
Supports up to 700 MB total. Zipping runs in the background — this tab stays responsive.
Click to add files
ZIP Creator is a free online tool that bundles multiple files into a single ZIP archive, entirely in your browser using JSZip — no upload, no software, and works with any file type. Zipping runs in a background Web Worker so the page stays responsive, with a live progress bar and a Cancel button.
Is ZIP Creator free to use?
Yes, it's completely free with no signup required.
What file types can I zip?
Any file type — there are no format restrictions since files are added to the archive as-is.
Do you store my uploaded files?
No. The ZIP is built entirely in your browser, in a background Web Worker — files are never uploaded to a server.
Can I rename the archive or set a compression level?
Not currently — the tool creates a file named archive.zip using JSZip's default settings.
Is there a size limit?
Yes: the files you add can add up to 700 MB total on desktop (100 MB on phones and tablets) -- a measured limit to keep zipping reliable in the browser tab rather than risking a crash on a very large combined archive.
