Frequently asked questions
Is my file uploaded?
No. The conversion runs entirely in your browser. The file never leaves your device – there is no server that could see it. Once the page has loaded, the tool even works offline.
Which target should I choose?
−14 LUFS is what Spotify, YouTube and most streaming services level to; −16 LUFS is the usual value for podcasts and Apple Music; −23 LUFS is the broadcast standard EBU R128. Peaks are limited to −1.5 dBTP in every case.
Is the file re-encoded?
Yes – the sound cannot be changed without decoding it. Lossy formats (MP3, OGG, M4A, AAC) are re-encoded at 192 kbit/s, which is inaudible for practically everyone; WAV and FLAC stay lossless.
How fast is it?
Audio is quick: a three-minute song converts in a few seconds once the engine (about 32 MB, loaded once per visit) is ready. Files up to 100 MB are accepted.
