Local audio tools that run in your browser
Extract audio, convert to MP3 and transcribe speech — processed locally on your device, with no uploads.
Handle audio without the cloud
Our audio tools help you turn video into MP3, pull the soundtrack out of a clip and transcribe spoken words into text. They are useful for podcasts, meetings, interviews and music, where you often work with sensitive or lengthy recordings. Because everything runs in your browser on your own device, your audio is never uploaded and stays private from start to finish.
