GO DEEPER THAN VOLUME
Two focused ways to
shape a better mix.
Volume gets attention, but the right low end and frequency balance are what make a file feel finished. Open a focused workspace and hear the difference.
A REAL BROWSER WORKFLOW
From quiet file to
finished copy.
The web editor follows the same useful product sequence as the iPhone app while keeping the original file intact.
Import locally
Choose a supported audio file or MP4/MOV video. It stays in browser memory instead of being sent to a server.
Listen and shape
Set volume, add genuine low-frequency gain, use the five-band EQ, and switch between original and enhanced playback.
Process and download
The local processing engine creates a new M4A or MP4 copy with peak protection, ready for download.
BUILT LIKE A PRODUCT
More than a volume slider.
Large gain values are easy to advertise and easy to get wrong. The editor combines live A/B monitoring with explicit tonal controls and a final limiter, so you can hear the tradeoff before creating a copy.
- Non-destructiveYour source file is never overwritten.
- Honest bass processingA low-shelf filter changes your media instead of layering a generic bass loop over it.
- Export protectionA limiter controls digital peaks created by aggressive gain and EQ.

MADE FOR IPHONE
On iPhone, use the App.
The app is faster for repeat edits, keeps your imported media workflow together, and gives you the dedicated mobile experience that a browser cannot.
LEARN BEFORE YOU BOOST
Fix the cause,
not only the level.
Some quiet media needs gain. Some problems come from Bluetooth routing, speakers, clipping, or an already damaged recording.
FAQ
Questions, answered.
Can I increase audio volume online without uploading my file?
Yes. Volume Boost processes supported audio and video inside your browser. The file is not uploaded to our server, and the enhanced copy is created on your device.
Which files can I make louder?
The web editor accepts common audio formats including MP3, WAV, M4A, AAC, and FLAC. Video processing supports MP4, MOV, and M4V files with an audio track.
How loud can I make a file?
You can set output volume from 0% to 1000%. A peak limiter is applied during export, but large increases can still raise noise and reduce dynamics, so compare the loudest section before downloading.
Does the online volume booster work on iPhone?
It works in modern mobile browsers, but large files can exceed mobile browser memory. The iPhone app remains available for a more durable mobile workflow and file management.
Will this replace the original file?
No. The editor creates a new M4A audio file or MP4 video. Your original remains untouched.
Is the online tool free?
Yes. The browser volume booster is free to use. The site may display clearly separated advertising in the future to support the service.
