FAQ
Frequently asked questions
Is Volume Changer really free?
Yes — completely free, with no hidden fees, no premium tier and no signup required. The tool runs entirely in your browser.
Do I need to install anything to use Volume Changer?
No. Volume Changer works directly in your browser. There is no software to install, no app to download and no plugin required.
Is my video uploaded to a server when I use Volume Changer?
Never. All processing happens locally on your device. Your file never leaves your computer, which is why there is no upload wait and no privacy risk.
Which video formats does Volume Changer support?
It accepts MP4, WebM, MOV and MKV — anything your browser can decode. Output is MP4 by default, playable on any device.
What happens to my file after processing?
Nothing is stored anywhere. Once you close the tab, everything is gone. We have no server, no storage and no access to your files.
Will my video have a watermark?
No — every download is 100% watermark-free. EditVideo never adds logos, branding or watermarks to your files.
How much can I increase the video volume?
Up to 400% (4×). The presets are 100%, 200% and 400% — 400% is best reserved for very quiet recordings, as it can amplify background noise too.
