What is this tool?
This audio converter re-encodes files between the most common audio formats using FFmpeg compiled to WebAssembly — the same engine behind professional audio software. MP3 and M4A are encoded at 192 kbit/s, a quality level indistinguishable from the source for almost all listeners; WAV is uncompressed for editing. Because everything runs on your device, even long recordings stay private.
Common uses
- Converting voice memos (M4A) to MP3 for maximum compatibility
- Turning downloads into WAV for audio editing software
- Converting WAV recordings to MP3 to shrink them for sharing
- Making OGG files for games and web projects
FAQ
Is my audio uploaded to a server?
No. The conversion runs entirely in your browser. Only the FFmpeg engine (~31 MB) is downloaded from a CDN on first use and cached — your files never leave your device.
Does converting MP3 to WAV improve quality?
No — a lossy format like MP3 cannot gain quality back. Converting to WAV is useful for compatibility with editors, but the audio stays exactly as it was.
Can I convert a video file's audio?
Yes. Drop in a video file and the tool extracts and converts its audio track — handy for turning recordings into podcasts or music files.
