Frequently asked questions
Why convert WebM to MP4?
WebM is common on the web but unsupported by many consumer devices and apps. MP4 (H.264) is the universal fallback.
Which browsers can run this?
The browser must decode VP8/VP9 and encode H.264 — Chrome, Edge and recent Safari qualify.
Will the quality drop?
The file is re-encoded at high quality, so the difference is minimal while compatibility improves a lot.
