MP3 compared with WAV

Converting MP3 to WAV does not restore details lost during MP3 encoding. It changes compatibility and editing behavior, not source quality.

OutputWAVUse the new file for the compatibility or size goal above.
Inside the conversion

What FLUX actually changes

The MP3 is decoded to 16-bit PCM and written into a WAV container. No lossy encoder or bitrate control is used for the output.

Check after export: Check the sample length in the editor and plan for a much larger file; keep the MP3 if storage matters.
Private by default

Your file stays with your browser

FLUX does not send selected files to its own conversion server. Processing is handled locally on your device, while versioned conversion modules may be loaded securely when needed.

Compatibility

Before you start

Audio conversion runs in your browser and depends on the codecs available to the bundled media engine. Very large files need enough free device memory.

If a conversion stops: close memory-heavy tabs, try a shorter audio file, keep the page in the foreground, and confirm that the source plays from start to finish.
