Increase Audio Volume Online: Boost Your MP3s for Free
We've all been there: you download a song, record a voice memo, or receive a podcast file, and it's just too quiet. Even with your computer volume at 100%, you can barely hear it.
You need a volume booster. And you don't need to download complex audio engineering software to get it. You can increase audio volume online in seconds.
Why is My Audio So Quiet?
Low volume can happen for several reasons:
- Poor Recording: The microphone was too far away from the source.
- Low Gain Staging: The recording input levels were set too low.
- Compression Issues: Bad file compression can sometimes mess with perceived loudness.

Safety & Privacy
Does uploading your personal voice memos to a website feel unsafe? It should. That's why we don't perform server uploads.
Our Volume Booster works entirely in your browser using WebAssembly. Your audio data stays on your device, ensuring 100% privacy.
Tips for Better Audio
- Don't Over-boost: It's better to increase volume moderately than to distort the audio.
- Check Your Hardware: Sometimes the issue is your headphones or speakers, not the file.
- Use Normalization: If you have multiple files, try to normalize them so they are all the same volume.
