Before you start

ZIP files bundle many files into one. Open an archive to see what is inside before you extract anything, or add files and create a new archive. To protect your browser, very large archives and archives that expand to an unsafe size are refused. Password-protected ZIP files are not supported.

When to use it

Checking an archive's contents before opening it.
Bundling documents into one file for upload.
Splitting a download into a smaller set of files.

Limits: 500 entries, 100 MB ZIP, 300 MB expanded, 50 MB per extracted file. Entries with unsafe paths are blocked. Password-protected ZIPs are not supported. Nothing is run.

Privacy and file handling

Handled in your browser with a built-in ZIP reader and writer. Nothing is uploaded.

Troubleshooting

If a ZIP is refused it may be damaged, encrypted or over the limits.
