ZIP File Creator
Package files into a ZIP without uploading them
Choose files, give the archive a name, and download a standard ZIP built entirely in your browser using its native compression. The files never leave your device.
Files are compressed and packaged entirely in your browser; nothing is uploaded.
Everything on this page is processed in your browser. Nothing is uploaded.
What this tool does
Most online ZIP tools work by uploading your files to a server, zipping them there, and sending the archive back. This one instead uses the Compression Streams API built into modern browsers to deflate each file locally, then assembles a standard ZIP structure — local file headers, a central directory and the end-of-central-directory record — entirely in JavaScript. The result opens in any ordinary ZIP tool, since it follows the same format. On the rare browser without compression support, files are stored uncompressed instead of failing outright, so the archive still works, just larger.
How to use it
- Choose the files to add to the archive.
- Give the archive a file name.
- Create the ZIP and download it.
Privacy
This tool runs entirely in your browser. Your input is never uploaded, stored or shared — closing the tab removes it.
Frequently asked questions
- Are my files uploaded to build the ZIP?
- No. Compression and archive assembly both happen in your browser; the files are never sent anywhere.
- Can I unzip the result with any tool?
- Yes. It is a standard ZIP file that any ZIP-compatible tool, including the ones built into Windows, macOS and Linux, can open.
- What happens on a browser without compression support?
- Files are stored uncompressed instead. The archive is larger but still a valid ZIP that opens the same way.
