HELP

WHAT THIS DOES

Decodes MP3 audio to PCM using Web Audio.

Encodes to OGG/Opus (or WebM/Opus fallback) using MediaRecorder.

No uploads • everything runs in your browser.

HOW TO USE

1) Drop an MP3 or choose a file

2) Pick quality (hint only)

3) Press CONVERT, then download

Keyboard: ESC returns to PAGE 1

OGG SUPPORT

Some browsers can’t output .ogg.

If that happens, this page outputs .webm (Opus) instead.

The STATUS + OUT line show your exact output type.

LIMITATIONS

Very long audio files may be memory-heavy.

Mobile browsers may limit recorder features.

If conversion fails, try a shorter file or another browser.
