MKV to AVI questions
Short answers about limits, privacy, and keeping the converted file.
What happens to extra audio and subtitle tracks?
MKV files can carry several tracks. The AVI may include only the main video and audio, so check the result if you rely on alternate languages or subtitles.
Is the MKV to AVI converter free?
Yes. Without an account you can convert up to 10 files a day, 2 at a time, up to 15 MB each. A free account adds monthly conversion credits and larger files.
How long are my files kept?
Guest uploads and results are deleted automatically after 1 hour. Conversions stay temporary when you are signed in too, unless you save a result to your workspace.
Can I get a permanent link to the AVI file?
Yes. Save the result to a SteadyLink workspace and it gets a stable link. If you make a new version later, replace the file and the link stays the same.
