Supports MP4, WebM, MOV • Max 1GB
A video to MP3 converter extracts the audio track from a video file and saves it as a standalone MP3 audio file. Instead of keeping a large 1 GB video file just for its audio, you can extract just the sound — whether that's a song, a podcast recording, a lecture, or an interview — and save it as a compact MP3. ToolsWallet's converter runs entirely in your browser using WebAssembly-powered FFmpeg, which means your video never gets uploaded — it's converted locally on your device.
There are countless reasons why you might want just the audio portion of a video file. Here are the most common scenarios:
Every video file contains two separate streams: a video stream (visual frames) and an audio stream (sound data). Our converter uses FFmpeg compiled to WebAssembly to read your video file, locate the audio stream, and write it out as a standalone MP3 file — without re-encoding the video portion at all. This is called "stream copying" and it's both the fastest and highest-quality method of audio extraction. The entire process runs inside your browser with no internet connection required after the page loads.
