How to use this tool
- Drop in an audio file.
- Pick a target peak level and output format.
- Click Normalize — the tool scans the whole file first, then applies the calculated gain.
Frequently asked questions
- How is this different from a compressor or limiter?
- This applies one fixed gain to the whole file based on its single loudest peak — it doesn't change the dynamic range or relative loudness between quiet and loud parts, just scales everything up or down together so the peak lands where you want it.
- Why would I pick −1 dB instead of 0 dB?
- A small amount of headroom (−1 or −3 dB) avoids clipping if the file gets re-encoded or played through equipment that adds even a little extra gain. 0 dB pushes the peak to the absolute maximum with no margin for error.
- What if my audio is already louder than the target?
- The gain applied will be negative (a reduction) rather than a boost — the tool always scales the peak to exactly the target level, whichever direction that requires.
- Is my audio uploaded anywhere?
- No — both the peak-scanning pass and the gain adjustment happen entirely in your browser. Nothing is uploaded.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online tools |
|---|---|---|
| Data ever leaves your device | No — analyzed and processed in this tab | Yes, uploaded to process |
| Shows the exact gain applied | Yes, in dB | Varies |
| Account required | Never | Often, past a certain usage level |
