Turn up a too-quiet audio file. Upload, set how much louder in the convert step (2 = +6 dB), and download.
Volume is a multiplier — 2 is twice as loud (+6 dB), 1.5 a gentle lift. For a consistent, clip-safe loudness across a whole file, try the Normalize loudness option instead.
The louder audio is saved back in its own format, or pick another. Anonymous uploads are temporary and encrypted in transit.
Upload your file — it's pre-set to a 2× volume boost. Adjust the gain in the convert step and download.
Very high gain on already-loud audio can clip. Lower the multiplier, or use Normalize loudness for a clean, consistent level without clipping.
Yes — no account, over an encrypted connection, and anonymous files are temporary.
