Frequently Asked Questions
Why convert WebM to MP4?
While WebM is great for the web, MP4 is much better supported by offline players, editing software, and mobile devices (especially iPhone/iPad).
Is there quality loss?
MP4 uses modern compression (H.264) which is very efficient. In most cases, you won't notice any difference in visual quality.
Can I edit the MP4 file?
Yes, MP4 is the standard format for video editing. Virtually all video editors (Premiere, Final Cut, DaVinci) support it natively.
