How to convert ISO to 7Z
- Add your .ISO file - drop it in the box above or click to browse.
- Convert it to .7Z in a few seconds.
- Download your new .7Z file.
What to expect
- The files inside the ISO are extracted and recompressed; the result is not a mountable or bootable disc image.
- Boot sectors and disc-specific structure are not preserved.
- 7z compression usually makes the archive smaller than the source ISO.
Frequently asked questions
Does this keep the disc image or just the files?
It reads the files and folders stored inside the ISO and repackages them into a 7z archive, so you get the contents rather than a mountable disc image. The disc's sector structure and any boot information are not preserved.
Why convert an ISO to 7z?
A 7z archive is often smaller than the original ISO and is easy to browse, extract, and share without mounting a disc. It bundles the disc's files into one compressed container.
What opens a 7z file?
7-Zip on Windows, Keka on macOS, and p7zip on Linux all open it, and all are free. Many general archive tools also support it.
Is the result still bootable?
No. Because only the files are extracted and recompressed, the boot sectors that make an ISO bootable are lost, so the 7z cannot be used to boot or install directly. Keep the original ISO if you need that.
