Formats

23 formats in, 17 out, 148 conversions.

This table is generated from the conversion engine at build time, not written by hand. It cannot list a pair the engines don't actually perform — which is worth saying, because every competitor's format list is marketing copy and a good half of the entries fail once you try them.

That count is conversions between different formats, each of which has its own page. A further 16 formats can be re-encoded to themselves — useful for changing the quality or dropping the metadata — which is why picking the same format on both sides is allowed rather than refused.
