Files processed on your deviceFFmpeg runs locally in your browser. First use loads a roughly 32 MB same-origin WebAssembly core and can take time and use substantial memory. Combined inputs are limited to 100 MB, media duration to 30 minutes, frame dimensions to 4,096 pixels per side and 16 megapixels total, and output to 250 MB. Codec and filter support depends on the bundled build.
