01
Before you start
The file picker accepts: .7z, .bz2, .gz, .rar, .tar, .tar.bz2, .tar.gz, .zip, application/octet-stream. The contents and encoding of the file must also be supported; an extension alone does not guarantee compatibility.
The download uses the .tar.bz2 extension. Keep the source until you have checked the result.
02
What to expect
Use this tool to prepare an archive in the selected format. Compressing already compressed media may save little space. Check that your recipient has software that can open the resulting archive.
TAR.BZ2 combines a TAR archive with bzip2 compression. Compression can be slow on less powerful devices.
03
Limits to keep in mind
Archives are assembled in browser memory; very large jobs may exceed device limits.
Bzip2 compression can be slow on phones and TVs.
