What people use it for
- Music for the car
More weight in the low end for your car stereo.
- Hip hop, trap and electronic music
Strengthening the bass of a beat or a track that came out thin.

A little more bass makes up for headphones and speakers with little body.

- Workouts and parties
A playlist with more impact for the gym or a party at home.
Tips for a better result
- 01Start small.
Between 4 and 8 dB already makes a big change. Too much bass muddies the rest of the song.
- 02Test on headphones.
Phone speakers cannot play very low notes; on headphones or in the car the difference shows.
- 03Overall volume may drop a bit.
That is on purpose: the page lowers it only as much as needed to avoid distortion.
- 04Want to adjust the rest too?
The equalizer has five bands, from the deepest bass to the high-end sparkle.
Common questions
How do I make a song bass boosted?

Is this bass booster online free?
Yes, with no account and no limit. Your file is processed in your browser and not sent to any server.
Will it distort?
The page checks the loudest point and turns the volume down if needed, so it does not clip.
Does it work on small speakers?
It adds bass to the file, but a phone speaker still cannot play very low notes. Headphones show the difference.
