Should you convert CAF to OGG?

A lossless move: CAF and OGG both keep every sample, so the sound is identical and you can convert back at any time.

CAF is Apple’s professional audio container; OGG is open-source lossy audio, common in games and on Android. Use OGG for game engines, Android apps and open-source projects that prefer free formats.

How to convert CAF to OGG

  1. 01

    Add your CAF

    Drop your CAF file onto the box, or click to choose it. It is read from your disk and stays there.

  2. 02

    Check the settings

    The output is already set to OGG. Change the bitrate if you want to; the defaults suit most files.

  3. 03

    Save the OGG

    Press convert and save the OGG. Several files come back together as a ZIP.

What changes when CAF becomes OGG

Identical sound

Both formats are lossless, so the audio isn’t changed at all. Only the file size and which apps open it differ.

A one-time engine download

CAF is decoded by FFmpeg compiled to WebAssembly, a 31 MB download the first time. After that it is cached, and the conversion never leaves your device.

Expect a much smaller file

CAF: Depends on the codec inside. OGG: Similar to or slightly smaller than MP3. Shrinking the file is often the main reason to make this conversion.

This page is put together from our notes on each format, choosing only what is true of CAF and OGG, so every pairing states the same facts the same way. How these pages are made.

Why it doesn’t upload

Recordings are often private: interviews, voice notes, unreleased music. Your browser can decode and encode audio itself, so there is no reason to send it anywhere.

How to check for yourself

Worth knowing

  • About the CAF. A CAF can hold uncompressed PCM, AAC or Apple Lossless, so two CAF files of the same length can differ tenfold in size.
  • About the OGG. The .ogg extension can hold Vorbis, Opus or FLAC audio, so one OGG plays in a player and the next doesn’t.
  • MP3, WAV, M4A, OGG, Opus and FLAC are converted by your browser directly. WMA, AMR, APE, AC3 and the other specialist formats use the FFmpeg engine, a one-time 31 MB download.

Questions

Does converting CAF to OGG lose quality?

OGG is lossy, so a little is discarded, but at the default bitrate the difference is inaudible for nearly everyone.

Will an OGG play in my car or on my phone?

OGG has patchy support: Android, Chrome, Firefox and VLC, but not every Apple app, car stereo or editor.
