What it does
The tool measures perceived loudness and adjusts the whole file to -16 LUFS with a -1.5 dB ceiling, the level podcast and streaming platforms recommend.
When to use it
Podcasts, voice-overs, lectures and playlists where some files are much quieter than others.
Private by design
Most online tools upload your file to their servers. This one doesn't: it loads into your browser and does the work on your own phone or computer, so your files never leave it.
