FAQ

Does WebM create smaller files than MP4?

Often, yes. WebM utilizes the efficient VP8 or VP9 codecs, which can sometimes squeeze the visual data tighter than an older MP4 H.264 stream.

Will this work on mobile devices natively?

Most modern Android browsers support it natively. However, iOS Safari has historically forced users to rely on MP4 fallbacks.

Can I queue up multiple files?

Yes, select a batch of files at once, and our local processing engine will handle each encoding step sequentially.
