Common questions
Why convert AVI to WEBM?
AVI is an old, heavy format. WEBM is the modern, open format for web video — it plays natively in browsers and HTML5 players at a much smaller size.
Will the quality drop?
We re-encode at a high quality, so it looks essentially the same while the file gets much smaller thanks to WEBM's efficient compression.
Do all browsers play WEBM?
All current major browsers support WEBM. For very old software, MP4 has the widest reach.
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.
