FAQ

Frequently Asked Questions

Answers to the most common questions about Convrs.

How do I convert audio to louder audio for free?
Select your audio file (or drag and drop it), click Convert and download the louder audio result. There is no sign-up, no cost, and the file never leaves your browser.
Is Volume Booster private and secure?
Yes. Volume Booster runs entirely in your browser, so your data never leaves your device — nothing is uploaded or stored on a server. Video and audio tools use a WebAssembly engine that also runs in your device's memory.
What happens when I boost the gain?
Raising the gain makes audio louder. Boosting too far past 0 dB causes peaks to clip and distort, so a small boost sounds best.
What is the maximum file size?
100 MB per file. Because everything runs in your device's memory, very large files can slow down or freeze the browser.

About this tool

audio → louder audio: a complete walkthrough

Volume Booster takes your audio and turns it into louder audio — completely inside your browser. No install, no account, no watermark: you select or drop a file, review the settings, and download the result seconds later. Your files stay on your device.

Media files are the heaviest and most sensitive things you handle. Processing them in place means the audio or video never crosses the network: no upload progress bar, no server logs, no copy left behind — just the result on your device.

Privacy by construction: Volume Booster runs entirely in your device's memory. Your files, text and data are never uploaded, stored or logged by us — there is no server in the path.

The heavy lifting uses WebAssembly: the same codec engines a desktop app would use are compiled to run inside your browser, so Volume Booster delivers desktop-grade results while the file stays on your device.
