MP4, WebM, MOV, and AVI. Some tools also support MKV and other formats.
Is there a file size limit for videos? ▼
We recommend files under 500MB for optimal browser performance. Larger files will work but may be slower.

Video encoding is computationally intensive. Processing happens on your device, so speed depends on your computer's capabilities.
