How to Normalize Audio
Drop a video or audio file and the tool evens its loudness to the streaming standard. Video stays pixel-for-pixel the same — only the sound level changes.
Tip: -14 LUFS is the loudness target YouTube and Spotify use, so normalized audio matches them.

FAQ
Frequently asked questions
Is Audio Normalizer 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 Audio Normalizer?
No. Audio Normalizer 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 Audio Normalizer?
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 Audio Normalizer support?
Videos come back as H.264 MP4 with the picture untouched; audio-only files come back as M4A.
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.
What does audio normalization do?
It measures overall loudness and adjusts it to one consistent level — quiet recordings get louder, loud ones settle down, without clipping or pumping.
Does normalization affect my video quality?
No — the video stream is copied untouched. Only the audio level changes.
What's the difference between normalization and volume?
Volume multiplies the whole track by a fixed amount — quiet parts stay relatively quiet. Normalization measures the track and levels it to a loudness target, so quiet and loud sections sit consistently.
Can I normalize audio on my phone?
Yes — it works in any modern mobile browser. Drop a video or audio file from your phone and download the normalized version straight back.
