Como Converter Vídeo para MP3 Online — Privado e Gratuito

Aprenda a extrair áudio de qualquer arquivo de vídeo completamente dentro do seu navegador. Sem uploads, sem servidores, 100% privado usando ConvertCraft.

Whether you want to rip a podcast intro from a video lecture, save a song from a concert recording, or extract dialogue from a clip, converting video to MP3 is one of the most common file tasks on the web.

Most video-to-audio converters require uploading your file to a server, which is slow for large videos and a privacy risk if the content is personal or confidential. ConvertCraft handles the entire extraction in your browser using FFmpeg compiled to WebAssembly.

How it works: 1) Open the Audio Converter tool. 2) Drop your video file (MP4, WebM, MKV, AVI, MOV). 3) Select MP3 as the output format and choose a bitrate (128k, 192k, or 320k). 4) Click Convert and download the audio file.

A conversão é rápida — um MP4 de 1080p 5 minutos normalmente converte para MP3 em menos de 10 segundos em um laptop moderno. Como nada é subenciado, não há restrições de tamanho de arquivo além da sua memória de navegador disponível.

ConvertCraft suporta extrair áudio para vários formatos além de MP3: FLAC, OGG, WAV e AAC estão disponíveis. Você também pode cortar o áudio para extrair apenas uma parte do vídeo.
