Inside the conversion

What FLUX actually changes

FLUX decodes MP3 and uses the Vorbis encoder at q4, q5, q7, or q8 rather than treating those choices as fixed bitrates.

Check after export: For games or loops, test the seam and playback engine directly; re-encoding can alter encoder delay and loop timing.
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.
