Frequently Asked Questions

Where do WebM files come from?+

Browser-based screen recorders, Discord clips, OBS and many web apps output WebM — it's the web's native video format, but support outside browsers is weak.

Why convert to MP4?+

Video editors like Premiere, phones, smart TVs and many upload forms either reject WebM or handle it poorly. H.264 MP4 is the universal answer.

Is quality preserved?+

The video is re-encoded at high quality (CRF 23) — visually equivalent for screen recordings and typical footage.

Is my recording uploaded?+

No — conversion runs fully in your browser, which matters for screen recordings that often contain sensitive information.
