Supported files
The fixed profile maps only the first audio stream, removes source metadata and chapters, then creates a fresh OGG. It is not a stream copy.
How it works
Add a non-empty .m4a file up to 100 MB that host FFmpeg can read and that contains audio.
Files are submitted one at a time to map the first audio stream and encode Vorbis at quality 5.
Review the completed audio where browser support permits, then save its separately named .ogg file.
