Audio Converter
Convert MP3, WAV, M4A, OGG or FLAC to MP3 or WAV. The file is decoded, converted and re-encoded locally in your browser — nothing is uploaded.
How it works
- Drop an audio file or click to choose one. It stays on your device.
- Pick MP3 or WAV as the output, and a bitrate if you chose MP3.
- Press convert, then download the result.
Frequently asked questions
What input formats does this accept?
Drop MP3, WAV, M4A/AAC, OGG or FLAC — anything your browser's Web Audio API can decode. Browser support for FLAC and OGG varies slightly by browser, but Chrome, Edge and Firefox handle all of these.
Why can I only export MP3 or WAV?
Browsers don't ship built-in encoders for M4A, OGG or FLAC, so this tool can only reliably produce MP3 (via an in-browser encoder) or WAV (uncompressed PCM) as output. Those two cover almost every use case, from small shareable files to exact-quality originals.
Is my audio uploaded anywhere?
No. The file is decoded, converted and re-encoded entirely locally in your browser — nothing is uploaded, and the audio never leaves your device.
Does converting lose quality?
Converting to WAV is lossless — it's the same uncompressed PCM the browser decoded. Converting to MP3 is lossy, like any MP3 encode; a higher bitrate keeps more of the original detail at the cost of a larger file.
What bitrate should I pick for MP3?
192 kbps is a solid default for music and podcasts. Drop to 128 kbps for smaller files where quality matters less, or go up to 256-320 kbps if you want it close to indistinguishable from the source.
