Why convert 7Z to ZIP?
7Z archives compress well, but Windows (before recent updates), macOS and phones often cannot open them without extra software. ZIP opens everywhere with a double-click, so converting 7Z to ZIP makes the files easy for anyone to unpack.
When to keep the 7Z
Keep the 7Z if you and the people you share with have 7-Zip: it is usually smaller.
Tips for the best result
- All files and folders are repacked into the ZIP with the same structure.
- The ZIP may be a little larger than the 7Z.
- For safety, archives that unpack to a very large size are refused.

Frequently asked questions

How do I convert 7Z to ZIP?
Click Select File or drop your 7Z file onto the upload box. The converted ZIP appears in the list below with a download button. You can add many files at once and download them together as a ZIP.
Is it really free?
Yes. There is no sign-up and no watermark. To keep the service available for everyone there is a 95MB limit per file and a cap on how many files one connection can process in a short period.
Are my files stored?
Your upload is used only to make the converted file. Images are processed in memory; other files are written to a private temporary folder that is deleted as soon as the conversion finishes. Nothing is kept after the result has been sent back.
Will quality drop?
For images, a little, by design: the image is re-encoded at the Quality you choose (default 75%). Audio and video are re-encoded with high-quality settings; documents keep their text and layout as far as the target format allows. Converting never restores detail that is already missing from the original.
How this works: your file is uploaded over HTTPS and converted on this server with open-source engines (libvips for images, FFmpeg for audio and video, LibreOffice and Pandoc for documents, Calibre for ebooks, Ghostscript and Inkscape for PDF and vector files). Images are processed in memory; other files use a private temporary folder that is deleted as soon as the conversion finishes.
