Drop videos here or click to browseMP4, MOV, MKV, AVI, WebM, FLV, WMV…or paste from clipboard (Ctrl / ⌘ + V)
Accepted inputs: MP4, MOV, MKV, AVI, WebM, M4V, 3GP, FLV, WMV, MPEG / MPG, TS, M2TS, OGV — and most other formats. Everything is transcoded to MP4 (H.264) or WebM (VP9) with ffmpeg in your browser; the engine downloads once (~31 MB). Best for phone clips and short videos — very large files can exceed the browser's memory.
