MP4 for Universal Playback
MP4 is the safest pick for YouTube, social platforms, Slack, and every modern device.
WebM for the Open Web
WebM gives you smaller files at comparable quality, perfect for embedding on your own site.
MOV / MKV for Editing & Archive

Instant-Play MP4
MP4 output is optimized to start playing instantly when shared online.
100% Private & Free
Your footage never leaves your device — everything runs right in the browser tab.
Zero Server Upload
