How to convert ZIP to 7Z
Re-pack a ZIP as 7Z to make it smaller, often 10–40% smaller depending on what's inside.
- Drop your ZIP file into the box above, or add it from a link.
- 7Z is already selected. Use the settings button next to it to change size, quality or other options.
- Select Convert, then download your 7Z file.
To do this from your own code, call the FileForge API with "output_format": "7z".
Good to know
- Text, documents and code compress much better; photos and videos are already compressed and barely shrink.
- Recipients need 7-Zip or a similar app to open 7Z files.
About the formats

ZIP is the most common archive format. Windows, macOS, Android and iOS can open it without any extra app.
.7z
7Z is the 7-Zip archive format. It usually compresses better than ZIP, but Windows and phones need an extra app to open it.
