7z converter
A 7z archive repacks to ZIP in your browser, so its contents never leave your device. The files are read and rezipped locally, free.
What is 7z?
7z is the 7-Zip archive format, prized for compressing smaller than ZIP thanks to its LZMA algorithm. The catch is reach: opening a .7z usually means installing 7-Zip, since most operating systems unzip ZIP out of the box but not 7z. Repacking to ZIP keeps the contents and drops the dependency.
