Zip and unzip files in your browser

Drop several files to pack them into one .zip, or drop a .zip to see what’s inside and download any file from it. You don’t need WinZip, 7-Zip or an app, which helps on a work laptop or a borrowed computer. Folders inside an archive show in the file name, so you can see where each file sat. Your files never leave your device.

Zip or unzip: how the page decides

You drop It does
One .zip file Opens it and lists the files inside
Any other files (or a .zip plus other files) Packs them all into a new ZIP

When to use it

  • Send many photos or documents as one attachment.
  • Open a ZIP from email on a computer without unzip software.
  • Pull one file out of a large archive.

Tips

  • Rename files first if two have the same name.
  • ZIP doesn’t shrink JPGs or PDFs much. Use Compress image or Compress PDF for real savings.

Limits

Only standard .zip archives open. RAR, 7z and password-protected ZIPs don’t. Very large archives can run out of memory.
