Questions
Is the Volume Booster free?
Yes, 100% free. No sign up, no watermark and no limits.
Does my file get uploaded?
No. Your file never leaves your device. Everything happens right in your browser, so it stays private and works on unreleased tracks, beats and voice memos too.
How do I make an audio file louder?
Drop your file in the box, pick a boost like +6 dB or move the slider, press Play to check, then click Export MP3.
Will boosting the volume make it distort?
A limiter catches the loudest parts so they don't clip. Very big boosts squash the sound, so go up step by step.
How much louder is +6 dB?
About twice as loud to your ears. +12 dB is about four times as loud.
Can I make a quiet voice recording louder?
Yes. This is perfect for quiet voice memos, lectures, interviews and phone recordings.
Can I make a quiet song louder?
Yes. Saved files are also brought up to full level automatically.
Does it work on my phone?
Yes. It works on iPhone and Android in your normal browser.
Can I download the louder file?
Yes. Click Export MP3 or Export WAV.
What file types can I use?
Any audio your browser can play: MP3, WAV, M4A, FLAC, OGG and more. Save the result as MP3 or WAV.
No sound on my iPhone?
Turn off silent mode (the switch or Action button on the side), turn up the volume, and press Play again. Older iPhones mute web audio in silent mode.
