Are my BZ2 files uploaded anywhere?

Yes — this conversion needs software that cannot run in a browser, so the file is uploaded over an encrypted connection. It is deleted as soon as the job finishes, and the result is removed after 60 minutes.

Is converting BZ2 to 7Z free?

The free plan covers three server conversions a day, for files up to 25 MB. There is no watermark on the result.

Does converting BZ2 to 7Z lose quality?

No. 7Z stores the same content without discarding anything, so the result is identical in quality to the original. The files come out byte for byte. What does not survive is anything the container held about them rather than in them — a password, and on some formats the original permissions and timestamps.

Do I need to install anything to open 7Z files?

No. The conversion runs on our side and gives you a finished 7Z file; opening it needs whatever software normally handles 7-Zip Archive.
