How to convert 7Z to ZIP
- Add your .7Z file - drop it in the box above or click to browse.
- Convert it to .ZIP in a few seconds.
- Download your new .ZIP file.
What to expect
- The resulting
zipis almost always larger than the original7z- sometimes 10-30% - because ZIP's Deflate is less efficient than 7Z's LZMA2. - If the
7zis password-protected, you must unlock it during extraction; standard ZIP encryption (ZipCrypto) is much weaker than 7Z's AES-256, so do not rely on it for sensitive files. - Folder structure and file names carry over intact; the files inside are not modified.
Frequently asked questions
Is the conversion lossy?
No - the files are extracted and repacked without modification. Only the container format and compression level change.
Why is my ZIP larger than the original 7Z?
7Z uses LZMA2 compression, which is more efficient than ZIP's Deflate, so the same files take more space in a
zip container.Can I convert 7Z to ZIP on Windows without extra software?
Not fully - Windows cannot open a
7z file natively, so you need a tool like 7-Zip for the extraction step even if Windows can create the ZIP itself.Do split 7Z archives work?
Yes - put all parts (
.7z.001, .7z.002, etc.) in the same folder, open only the first part to extract everything, then create the ZIP normally.Programs that convert 7Z: PeaZip · WinRAR · 7-zip · ALZip for Mac · EZ7z for Mac OS X · Zipeg for Mac · sArchiver · StuffIt for Mac
