Why MP3?
MP3 is the most universal audio format: it plays on every phone, car stereo, browser and media player. Converting to MP3 is the safe choice when you want a file that simply works everywhere, at a small size.
Extract audio from a video
Drop an MP4 (or MOV) and keep only the soundtrack as MP3 — great for turning a talk, interview or music video into a file you can listen to anywhere.
Convert between audio formats
Have a WAV that's too heavy, an M4A from an iPhone, or a FLAC you want to play in the car? Convert any of them to MP3 in a couple of clicks.
Choose your quality
Pick a higher bitrate for music or a lower one for voice and smaller files. You stay in control of the size-versus-quality trade-off.
Private by design
Unlike typical online converters that upload your files, GetFormat processes everything locally using WebAssembly. Nothing is sent to a server — your recordings and videos stay yours.
