Important
Check the result before relying on it
Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.
Practical details
What this Lucaden tool does
Choose compact MP3 for sharing or PCM WAV for an uncompressed editing source. The video stream is discarded and only the decoded audio is written to the output.
Lucaden writes the source into FFmpeg's temporary in-browser file system, creates the output, then removes both temporary files. The source media is not uploaded to Lucaden.

Questions
About this tool
Which output should I choose?
MP3 is smaller; WAV is much larger but avoids another lossy audio encode.
Can a silent video be processed?
No useful output is possible when the file has no decodable audio stream.
