Runs FFmpeg inside your browser. Pressing the process button loads about 32 MB of engine files from unpkg, with jsDelivr as a fallback. The engine is reused while this page stays open; later visits may download it again depending on browser caching.

Large clips may take several minutes. +6 dB is roughly twice as loud to the ear's peak level; the limiter stops loud parts from distorting.
