About this tool
Converting audio here means decoding whatever format your browser understands into raw samples, then writing those samples back out as a WAV file — a real, lossless conversion for the decode step, though the destination format is always WAV rather than a choice of several compressed formats.
How to use it
- Upload an MP3, OGG, M4A, FLAC or other browser-playable audio file.
- Its duration, sample rate and channel count are shown once it decodes successfully.
- Press Convert to WAV and download the result.
Examples
Common problems
- The upload fails to decode at all.
- The file may use a codec your specific browser doesn't ship a decoder for (uncommon, but happens with some AAC/M4A variants in some browsers) — try a different browser, or convert with a desktop tool that bundles its own codecs.
