Uses a locally hosted FFmpeg.wasm encoder. The first run loads about 30 MB; remux is preferred for H.264/AAC MOV files.
Frequently Asked Questions
Are videos uploaded to a server?
No. Conversion runs locally with FFmpeg.wasm and its library assets are served by PigeonCast.
Remux vs re-encode?
Remux copies compatible streams into an MP4 container. Re-encoding supports more codecs but takes longer.
File size limits?
Files at least 1 GB show a warning. Files at least 2 GB are rejected because browser memory may not handle them reliably.
