WEBM to CAF Converter

Convert WEBM files to CAF. Free, without uploading.

This tool converts WEBM files to CAF. WEBM is an open video format built for the web (VP8/VP9 video, Opus audio). Browsers play it natively.

Apple Core Audio. Only the audio of the WEBM video is kept and saved as CAF; the picture is dropped. CAF is lossless, so the audio keeps the quality it has in the WEBM file.

Conversion runs on your device; your file is never sent to a server. The components download once on first use, and later conversions start right away.

How to use

1. Choose the WEBM video, drag it in, or paste its link.
2. Choose the audio quality; optionally enter a start and end time.
3. Press "Convert" and download the CAF file.
