Questions

About converting 7Z to TAR.GZ.

Can I convert a password protected 7Z?

No. Encrypted archives are rejected with a message, as entering a password is not supported yet.

Are the folders of my 7Z kept?

Yes. The TAR.GZ has the same folders and file names as your 7Z, including names with accents or other alphabets.

Do scripts stay executable?

Yes. Files that were executable stay executable in the TAR.GZ. Owner names are not stored, so the files belong to whoever unpacks them.

Do I need an account?

No. Up to 20 files a day work without an account, and the results have no watermark.

What happens to my files after the conversion?

Your files are processed on servers in the EU and deleted automatically after 24 hours.
