Convert 7Z to ZIP online
Convert 7z to ZIP when the recipient does not have 7-Zip installed. 7z compresses better, but ZIP is the format every operating system opens natively with no software and no instructions — which usually matters more than the space.
When should you convert 7Z to ZIP?
- Send an archive to someone who cannot open 7z
- Upload to a system or a form that only accepts ZIP
- Attach files to an email that recipients can open on a phone
- Distribute a download without telling people what to install
Before you convert
The archive will get larger
Every file is decompressed and recompressed with ZIP's weaker algorithm. The contents are byte-identical; the file is bigger. That is the price of universal compatibility.
Already-compressed contents barely change
If the 7z is full of JPEGs or MP4s, the size difference will be small — there was little compression happening in either format.
What happens to your file
The 7Z archive is extracted into a temporary working directory and repacked as ZIP. Everything happens in a directory that is removed afterwards even if the job crashes, so nothing is left behind on the server.
Settings this conversion runs with
| Source family | Multi-file archive |
|---|---|
| Target family | Multi-file archive |
| Contents | Byte-identical after repacking |
What changes
- Every file is fully decompressed and recompressed, so the contents are byte-identical but the archive size will change with the new algorithm.
