Limits
Starting point: MPV - MPV holds elementary MPEG video streams without a container wrapper. No audio can be stored, so pair it with a separate track. Only the embedded video track converts; scripts and buttons are dropped. Encode SWF (Sorenson Spark / MP3) from MPV at a bitrate near the source, and confirm the audio track before converting.
How conversion works
Conversion runs entirely in your browser with FFmpeg WASM. Files never leave your device.
