Common questions
Is it free?+
Yes — convert ZIP to 7Z free. Paid plans add larger files, batch and priority.
Is my archive private?+
Uploads go to a private bucket, are converted, and auto-delete after 1 hour. Files never touch a third-party converter.
Are my files changed?+
No — contents are extracted and repacked unchanged. Every file comes out byte-for-byte identical.
