● WHAT THIS DOES
This tool adjusts the loudness of your songs to match the level streaming platforms expect, measured in LUFS (Loudness Units Full Scale). If your track is too quiet, streaming services will boost it and you lose control over the sound. If it's too loud, they'll turn it down. Normalizing it yourself first means it plays back the way you intended.

01 PICK A TARGET LOUDNESS
Click a preset button for the platform you're releasing to:
- Spotify-14 LUFS
- YouTube-14 LUFS
- Apple Music-16 LUFS
- Tidal-14 LUFS
Or type your own number into "Custom Target" if you have a specific LUFS value in mind.
02 LOAD YOUR TRACKS
Drag one or more audio files onto the drop area, or click it to browse your computer. WAV, MP3, FLAC, OGG, and M4A all work.
03 CHOOSE AN OUTPUT FORMAT (optional)
In the Queue section, pick WAV (highest quality, larger file) or MP3 at 320/192/128 kbps (smaller file, slight quality loss). WAV is selected by default.
04 NORMALIZE
Click "NORMALIZE ALL." Each track is measured, then adjusted to hit your target loudness. You'll see the measured loudness, the target, and how much gain was applied for each file.
05 DOWNLOAD
Once a track is done, click its "DOWNLOAD" button to save it. If you loaded multiple tracks, click "DOWNLOAD ALL (.ZIP)" to get everything in one file.
● A NOTE ON "ADVANCED SETTINGS"
There's a "True Peak Ceiling" setting (default -1 dBTP). This is a safety limit — if boosting a quiet track up to your target loudness would cause it to clip or distort, the tool automatically applies less gain to keep the peaks safely under this ceiling instead. You usually don't need to touch this.
● TIPS
- If a track sounds noticeably different after normalizing, it just means the original was much louder or quieter than your chosen target — that's expected and is the whole point of the tool.
- You can normalize the same file to different targets by changing the target loudness and re-running "NORMALIZE ALL."
- Nothing is saved automatically — download your files before closing the tab.
