OGA to CAF Converter

Why convert OGA to CAF?

Moving OGA audio to CAF is about compatibility and size — which players accept the file and how much disk or bandwidth it costs once it gets there. CAF (Core Audio Format) earns its place here: unlimited file length with high-resolution, uncompressed audio. OGA is the Ogg container carrying Vorbis, FLAC or Opus audio. It is open and efficient, and still ignored by a lot of consumer hardware.

When OGA → CAF is the right move

• A player, car stereo or editing app in your workflow refuses OGA but handles CAF.
• You are consolidating a music or recording library into a single format instead of a mix of OGA and others.
• You need the file to be smaller, or conversely to stop losing quality, when moving from OGA to CAF.

Quality, size and what changes

The audio is decoded and re-encoded, so the running time, channels and sample content stay intact while bitrate and file size follow CAF. Going from a compressed OGA file to any other lossy format is a second generation of compression — start from the highest-quality source you have when it matters, and expect a lossless target to grow the file rather than improve the sound.

What you gain with CAF: Unlimited file length with high-resolution, uncompressed audio.

How it works

Drop your OGA file above and Morphio decodes it locally, then re-encodes it as CAF using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle. See exactly how in-browser conversion works.
