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
The converter normalizes the container and codec into a predictable MP3 or PCM WAV result. It is designed for short and moderate files that fit comfortably in browser memory.
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

Yes. MP3 is lossy, although higher quality presets reduce audible artifacts.
