How it works
The AI analyzes it
It measures loudness (LUFS), true peak, clipping, DC offset and sample rate, and picks the optimal settings.
Download the result
16- or 24-bit WAV or 128 to 320 kbps MP3, verified and ready to use.
✦ What the AI does with your file
- Picks the bits, kbps and sample rate for the destination.
- Prevents clipping: if the true peak would distort the file, it lowers the level just enough.
- Fixes DC offset when the wave is not centered.
- Applies dither when reducing to 16 bits.
- Warns you if the original was already clipped.
FLAC and MP3: what changes
FLAC is a lossless compressed format: it takes about half the space of a WAV and keeps the audio identical, but not every program or player accepts it.
MP3 is a lossy compressed format: it is small and plays on any device, but it discards part of the audio information to reduce the size.

Frequently asked questions
What about 96 or 192 kHz FLAC files?
MP3 supports up to 48 kHz, so the AI takes the audio to 48 or 44.1 kHz depending on the original and encodes it at 320 kbps. If you want to keep the high resolution, convert to WAV.
What does the AI do when converting?
Before converting, it analyzes your audio: loudness (LUFS), true peak, clipping, DC offset and sample rate. From that it picks the settings (bits, kbps, sample rate), lowers the level only if the file would clip, fixes DC offset and explains every decision.
Is my file uploaded to a server?
No. Conversion and analysis happen in your browser; the file never leaves your computer or phone. That is why it is fast and private.
Is it free? Are there limits?
It is free, with no sign-up, no watermark and no file limit. The only limit is your device’s memory with very long files.
Which formats does it accept?
MP3, WAV, FLAC, M4A (AAC), OGG and others your browser can read. You can convert to 16- or 24-bit WAV, or to MP3 from 128 to 320 kbps.
