Convert CAF to MP4 — Free Online Converter

CAF is Apple's professional audio container, native to macOS Core Audio and Logic Pro. MP4 (MPEG-4 Part 14) is the universal multimedia container for audio, video, and metadata. MP4 is required by YouTube, Facebook, Instagram, TikTok, and every major video platform.

Converting CAF to MP4 encodes the audio (typically to AAC) and packages it in the universally compatible MP4 container. This is needed when macOS professional recordings must be uploaded to video platforms, combined with visual elements, or served through web streaming systems.

Video platforms require MP4 format. CAF files cannot be uploaded to YouTube, Facebook, or any social media platform. Converting CAF audio to MP4 (optionally with a static image) enables platform distribution. MP4 also provides streaming features (faststart, HLS/DASH compatibility) that CAF lacks.

The MP4 container is the universal standard for web audio and video delivery, supported by every browser, device, and platform in existence.
