What this tool does
TubeCraft analyzes each selected track, applies a gain adjustment toward the chosen target and measures the result again. Available targets include −14 LUFS for common online video use, −16 LUFS for podcast-style delivery, −11 LUFS for louder material and −24 LUFS for broadcast-style workflows. These presets are references rather than guarantees that every platform will play the track at the same volume.
Check the result: Normalization does not repair clipping, noise or poor recording quality. Always listen to the exported audio and check the displayed measurements before release.

Private browser processing
Your selected media stays on your device during processing. The site downloads the code and model files required for the selected task, so the first run can take longer. Processing speed and memory use depend on the device.
Frequently asked questions
Does Audio Loudness Normalizer upload my media?
No. The selected media is processed in your browser. Loading the page, processing libraries and anonymous site analytics still use network data.
Is the tool free?
Yes. It can be used without registration. Browser memory, file size and duration limits apply.
Why can processing fail?
A file may use an unsupported codec, exceed a stated limit or require more memory than the device can provide. Try a smaller file or a current desktop browser.
