Frequently asked questions

Which video formats can I convert between?

Video Converter currently supports MP4, MOV, MKV, WebM, and AVI, plus one-off tools like MOV to MP4, MKV to MP4, WebM to MP4, and MP4 to WebM if you already know your target format.

How do I know which format to pick?

MP4 is the safest default for sharing and playback almost anywhere. Use WebM for smaller files aimed at the web, MOV if you're editing on Apple software, and MKV if you need to bundle multiple audio or subtitle tracks.

Can I convert several videos at once?

This tool converts one video per job. Drop a file, pick a format, and convert. To handle a batch, run each file through in turn; each gets its own download link.

Do I need an account or subscription?

Universal PDF requires a Pro subscription. One subscription unlocks every tool on the site, cancel anytime.
