Frequently asked questions
Which video formats can I convert between?
MP4 (H.264/AAC), WEBM (VP9/Opus), MKV, MOV and AVI. Just drop a file and pick the output format.
Is the conversion done on a server?
No — it runs entirely in your browser with FFmpeg compiled to WebAssembly. Your video is never uploaded.
Why does WEBM take longer?
VP9 encoding is more CPU-intensive than H.264. For the fastest results, convert to MP4.
