About these ferramentas de áudio e vídeo
Extract audio, cut clips and turn video into GIFs without uploading a thing. These tools run FFmpeg compiled to WebAssembly (ffmpeg.wasm) directly in your browser, so your footage never leaves your device. The video engine (~32 MB) downloads once on first use and is then cached — after that, processing is fully local. Best suited to short clips; very large files can exceed a browser tab's memory. Pick a tool above to get started, or browse the full A–Z index.
Frequently asked questions
Meus vídeos são enviados?
Não — o processamento usa FFmpeg compilado para WebAssembly e roda localmente no navegador.
Por que a primeira execução demora mais?
O motor FFmpeg (~32 MB) é baixado uma única vez no primeiro uso e depois fica em cache.
