How it works

Three steps from a quiet upload to a file that’s ready for YouTube.

Pick a file

Choose a video or audio file from your phone or computer.

Measure and fix

TubeTune measures the full track, then normalizes it to around −14 LUFS with a −1 dBTP ceiling.

Download the result

Save the corrected file, review it, and upload it to YouTube.

Your media never leaves your device. Measurement and processing happen in this browser tab; TubeTune does not upload your files.

Frequently asked questions

Why is my video quiet on YouTube?

Your export may have loud peaks but a low average loudness. YouTube can turn loud videos down, but it does not reliably turn quiet videos up, so a quiet mix can stay quiet after upload.

Is my file uploaded anywhere?

No. TubeTune processes the file locally in your browser. It is not sent to TubeTune or stored on a server.

What does −14 LUFS mean?

LUFS measures perceived average loudness over time. Around −14 LUFS is a common target for YouTube playback—not a rule, but a useful reference point.

Is TubeTune free?

Yes. TubeTune’s loudness fixer, caption tool, and audio extractor are free to use.

Your file stays local

Analysis and normalization run on your device. Nothing is uploaded.

Video stays clear

Loudness fixes copy the picture unchanged. Baking captions rebuilds the picture with the text embedded.

Large files take time

Keep this tab open while the browser works. Under 500 MB is best on phones.
