Common questions
Why convert MKV to AVI?
MKV (Matroska) is a flexible container that some older devices and programs don't support. AVI is an older, very widely-compatible format that often works where MKV won't.
Will the quality change?
We re-encode at a high quality so it looks essentially the same. AVI compresses less efficiently than MKV, so the file is usually larger.
Will subtitles and extra tracks come across?
AVI has limited support for the multiple subtitle and audio tracks MKV can hold. The main video and audio convert; embedded extras may be dropped.
Is there a file size limit?
Free users get up to 25 MB without an account; Pro raises it to 500 MB per file with 3,000 credits a month.
