Converto

What it does

Free Video to MP3 Converter. Free online converter for MP3, MP4, WAV, WebM and more. Files are processed entirely in your browser and never uploaded anywhere.

Converto extracts and encodes the audio track from your video, or converts an existing audio file straight to MP3, using an FFmpeg build compiled to WebAssembly. Everything runs locally in your browser tab — your video or audio file is never uploaded, so conversion stays private and works even with large files, limited mainly by your device's memory. Yes — choose the High (192 kbps) quality option before converting to keep the audio close to the original bitrate; Medium (128 kbps) is a good balance of quality and file size. You can upload MP4, MOV, MKV, AVI, WebM video, or WAV, FLAC, M4A, AAC and OGG audio — Converto extracts or re-encodes the audio track and saves it as an MP3 file. Yes.…from converto.io
