Recommended setting

Start with a sensible output

Use a bitrate close to the source quality. A higher MP3 bitrate does not restore information already removed from the OGG file.

Both formats are usually lossy. The main reason to convert is compatibility, not an increase in sound quality.

Inside the conversion

What FLUX actually changes

The supported audio stream inside OGG—commonly Vorbis—is decoded and re-encoded with libmp3lame. This is usually a lossy-to-lossy conversion, not a container rename.

Check after export: Test speech consonants and dense music sections, where a second lossy encode is easiest to hear.
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.
