Common questions
How loud can I make it?+
Up to +30 dB. Boosting a quiet recording a lot can introduce clipping or hiss: bump it in steps and you'll usually find a clean level. Lowering volume is always clean.
Does it work on video too?+
Yes. For a video we adjust the audio track and copy the picture untouched, so there's no video quality loss.
What formats work?+
MP3, WAV, M4A, AAC and more for audio; MP4, MOV, MKV, WebM and more for video. The result comes back in the same format.
Is it free and private?+
Yes. No watermark, no signup. Uploaded over TLS, processed on our own engine, deleted after 1 hour.
