Create ZIP files online

Create a ZIP file online for free with this in-browser ZIP maker. Add any number of files of any type — documents, images, PDFs, videos, audio, code — and bundle them into a single compressed .zip archive you can download in one click. Because everything runs 100% in your browser, your files are never uploaded to a server: there's no sign-up, no watermark, and no size limit beyond your own device's memory. Duplicate file names are handled automatically, and the files are kept in the order you add them. It's the fast, private way to zip files and compress files to a .zip for email, backup, or sharing.

🔒 100% private — files never leave your device

Frequently asked questions

What file types can I add to the ZIP?

Any file type. Create ZIP accepts files of any format — PDF, JPG, PNG, MP4, MP3, DOCX, CSV, code files and more — and bundles them all into one .zip archive.

Are my files uploaded to a server?

No. Everything runs 100% in your browser using the fflate library. Your files are read locally, compressed on your device, and never uploaded anywhere, so they stay completely private.

Is there a limit on how many files or how big they can be?

There's no fixed limit. You can add as many files as you like; the only practical limit is your device's available memory, since all files are held in memory while the ZIP is built.

Does it actually compress the files or just bundle them?

It compresses them. The tool uses deflate compression (level 6), so text and other compressible files get smaller. Already-compressed files like JPG, MP4 or MP3 won't shrink much, which is normal for any ZIP tool.

What happens if two files have the same name?

Duplicate names are handled automatically. If two files share a name, the tool adds (2), (3) and so on before the extension — for example report.pdf becomes report (2).pdf — so nothing gets overwritten inside the archive.

Can I choose the order or folder structure of files in the ZIP?

Files are added at the top level of the archive in the order you add them. You can remove files before zipping, but the tool doesn't create nested folders — every file sits at the root of the .zip.
