About this conversion
What happens
After consent, the audio uploads directly to temporary storage, metadata is removed, and an independent validator gates the result.
Limits
250 MiB input. 15 minutes, up to 0×0, and 100 MiB output.
Things to know
192 kbit/s is the balanced default. Higher bitrates increase size without restoring detail already absent from the source. Files with video, multiple streams, unsupported audio codecs, corrupt containers, or excessive duration fail safely.
