About this conversion
What happens
The worker verifies the WebM document type, converts offline after consent, removes metadata, and validates the MP3 independently.
Limits
250 MiB input. 15 minutes, up to 3840×2160, and 100 MiB output.
Things to know
Video is discarded. Re-encoding lossy source audio cannot improve it; 192 kbit/s is the balanced default. Non-WebM EBML, missing or unsupported audio, extra streams, excessive resources, timeout, or invalid output fail closed.
