Extract Crisp MP3 Audio from MP4

On iOS 13 and newer, Safari contains a built-in download manager and full Web Audio API support. Simply open ClipToAudio, select your MP4 from your Camera Roll or Files, click convert, and tap Download. Safari will prompt you to download the file directly, which can then be saved directly into Apple's Files App or imported into GarageBand and VLC.

Zero files are uploaded. Unlike legacy cloud converters that require uploading your private videos to remote servers, ClipToAudio operates 100% inside your web browser’s local client runtime using the Web Audio API and client-side stream decoding. Your videos never touch any external server.

Bitrate measures the amount of audio data processed per second. 128 kbps provides speech-optimized quality with minimal file size (approx. 1 MB per minute). 320 kbps is the maximum MP3 standard bitrate, capturing subtle audio dynamics, bass frequencies, and instrumental clarity (approx. 2.4 MB per minute).

Yes! Because there are no backend upload bandwidth bottlenecks or server file size caps, you are only limited by your device's available browser memory (RAM). Desktop computers can easily convert 2GB+ video recordings without waiting for uploads.

Because conversions run on the client side, we do not incur heavy cloud compute or bandwidth storage bills for video transcoding. This allows us to offer a fast, distraction-free, privacy-first tool without popups or intrusive advertising.
