Frequently asked questions
Any format the browser can decode: MP3, M4A, AAC, OGG, FLAC, OPUS, WEBM audio, and even some uncommon WAV variants. Chrome, Edge, Firefox, and Safari all support the same core set. The tool uses the Web Audio API to decode, so if the browser can play it natively, this tool can convert it.
WAV is the universal format — every audio tool on every platform accepts it. Encoding to MP3, OGG, or FLAC from scratch requires a WASM codec (lamejs, libvorbis, libflac) which adds several megabytes to the page load. We will ship MP3 output in a future version; for now, WAV covers every legitimate use case.
Yes. The decoded samples are exactly what the source encoder produced, and WAV stores them losslessly. If your source is a 128 kbps MP3, the WAV will be exactly as good as the MP3 — no better, no worse. If your source is a FLAC, the WAV is mathematically identical to the FLAC.
No. Everything happens in your browser. You can verify by opening the Network tab and converting a file — there are zero requests during the conversion process.
Because WAV is uncompressed. A 3-minute stereo 44.1kHz WAV is about 30 MB; a 3-minute 192 kbps MP3 is about 4 MB. MP3 throws away ~90% of the bits via psychoacoustic compression; WAV keeps all of them. The quality is the same, the file is just bigger by design.
Drop it into any audio editor (Audacity is free, GarageBand is built into macOS), import it to a DAW, feed it to a transcription service, or archive it. If you need a smaller file, use a different tool to re-encode the WAV as MP3 afterwards.
