without uploading your files.
Convert common audio formats directly in your browser. Formatify uses a browser version of FFmpeg, so your audio stays on your device during conversion.

HOW IT WORKS
Convert audio on your device
The conversion engine runs inside the browser. The first conversion loads FFmpeg WebAssembly, then Formatify processes your selected file locally.
Convert
Pick the output format and bitrate. Lossless outputs ignore the bitrate setting.
Download
Preview the converted audio and save it back to your device.
PRIVACY
Your audio is not sent to Formatify
Conversion happens locally in your browser. The FFmpeg WebAssembly engine is loaded as a web resource, but the audio file itself is processed on your device.
PERFORMANCE
Large files may take longer
Browser-based audio conversion uses your device's CPU and memory. Short clips usually finish quickly, while large or lossless files can take noticeably longer.
