Audio Converter
Change audio files between WAV, MP3, WebM and OGG formats without uploading anything. The conversion runs fully in your browser, so your recordings and music stay private, and you can download the converted file in seconds.
No file loaded yet. WebM and OGG export plays the audio once in real time to record it, and depends on browser support.
How to use
- Choose an audio file in any common format.
- Pick the target format.
- Click convert. WAV and MP3 render instantly, WebM and OGG record in real time.
Decoding uses the Web Audio API, MP3 encoding uses lamejs, and WebM or OGG uses MediaRecorder. If your browser cannot record OGG, the tool will tell you instead of making a broken file.
Tips
- Pick WAV for archiving or further editing — it keeps full quality but makes larger files.
- WebM and OGG export records the audio in real time, so keep this tab open and unmuted until it finishes.
- MP3 at 128 kbps is the practical choice for sharing — small files that play everywhere.
- If a file will not decode, try converting a WAV or MP3 copy of it first — some codecs and DRM-protected files are not supported.
