Mastering-grade conversion: proper 16-bit dithering, true peak control and LUFS in the response. Free, no sign-up, no watermarks.
WAV is the uncompressed distribution standard accepted by every platform and distributor. FLAC is the same audio, lossless, 30–50% smaller — perfect for archives and Bandcamp. MP3 320 is for quick sharing; avoid it for final distribution.
Direction matters too. FLAC to WAV and back is lossless both ways. A WAV made from an MP3 won't bring back what MP3 compression already discarded: bigger file, same sound.
16-bit WAV output gets TPDF dithering — without it quiet tails pick up audible quantisation artefacts. Peaks are checked against the −1 dBTP ceiling and corrected gently if needed so platform codecs won't clip. The response shows the file's LUFS and true peak — you instantly see if it's streaming-ready.
Up to 5 files a day per address, 100 MB per file. The converter never consumes your free mastering — the limits are separate. Files are not stored.
Upload the file on this page, pick MP3 and press «Convert». Encoding runs at 320 kbps and the file downloads straight away. Free, no sign-up, no watermarks, up to 5 files a day.
No. FLAC is lossless compression: unpacking it to WAV gives you the same signal bit for bit. A WAV made from an MP3, however, will not sound better than that MP3 — what compression threw away does not come back.
Mastering-grade conversion: 16-bit WAV output gets proper TPDF dithering, peaks are checked against a −1 dBTP ceiling, and the response shows the file's LUFS loudness and true peak — mass-market converters do none of this.
320 kbps, the maximum for MP3. That is plenty for sending a track quickly; for distribution to streaming platforms use WAV or FLAC.
