FreeVideoToAudio – Local video to audio conversion with full privacy

Summary: FreeVideoToAudio converts video files to audio formats entirely in the browser using WebAssembly, ensuring files never leave the device. It supports multiple input and output formats and works offline after the initial load.

What it does

The tool uses FFmpeg compiled to WebAssembly to process videos locally, converting formats like MP4, MOV, AVI, MKV, and WebM into audio outputs such as MP3, WAV, AAC, FLAC, and OGG without uploading files to any server.

Who it's for

It is designed for privacy-conscious users who want to convert videos to audio without risking file exposure online.

Why it matters

It eliminates the need to upload files to external servers, preserving user privacy and enabling offline use after the initial WebAssembly module loads.
