About this conversion
What happens
After consent, the audio converts offline with its admitted rate and channels preserved; independent RIFF validation gates download.
Limits
250 MiB input. 15 minutes, up to 3840×2160, and 200 MiB output.
Things to know
Video is discarded. The uncompressed WAV can be much larger than the source audio. Missing or extra audio, unsupported codecs, malformed MP4, excessive resources, or invalid WAV output fail safely.
