Private Audio Conversion

Most online converters upload your files to a server. This tool uses WebAssembly to run a professional audio engine (FFmpeg) directly in your browser.

Supported Features

Video Extraction: Drag in an MP4, MOV, or MKV to get the MP3 audio track.
Format Swap: Convert between MP3, WAV, AAC, OGG, M4A, and lossless FLAC, Opus, ALAC, and AIFF.
No Limits: Since it runs on your computer, there are no file size limits (as long as your device can handle it).

First Run Note

The first time you use this tool, it will download the audio engine (~25MB). This is a one-time download and will be cached for future use.
