Even out loudness across files so nothing is jarringly quiet or loud.

Nothing is uploaded. Your files are decoded, converted and re-encoded by WebAssembly running inside this tab, then handed straight back to you. The first conversion of a kind downloads that engine (a few MB for images, ~12–30 MB for video/audio) — later ones are instant.
Your files never leave this device — there is no upload and no server to delete them from.
About this tool
Applies EBU R128 loudness normalisation to −16 LUFS, the level streaming platforms target. Far more reliable than peak normalisation, which only looks at the single loudest sample.
