Free online OGG to ALAC converter

Source format

OGG is a container format most commonly used for Ogg Vorbis audio, though it can also hold other codecs such as Opus or FLAC. It is widely used for open, patent-free audio distribution, especially in games, streaming, podcasts, and software projects that prefer efficient compression and open standards. OGG files are valued for good sound quality at relatively small file sizes.

Target format

ALAC stands for Apple Lossless Audio Codec. It is a lossless audio format designed to preserve the original audio data while reducing file size. ALAC is commonly used in the Apple ecosystem, including iPhone, iPad, Mac, and iTunes/Music, and is a good choice when you want high-quality audio with broad support in Apple software and devices.

How to perform the conversion

The most reliable way to convert OGG to ALAC is to use a desktop audio tool that can decode OGG and encode ALAC. A practical option is FFmpeg, which is free, widely available, and supports both formats.

1. Install FFmpeg on your computer.
2. Open a terminal or command prompt in the folder containing your OGG file.
3. Run a command such as ffmpeg -i input.ogg -c:a alac output.m4a.
4. Check the resulting file in a player that supports ALAC, such as Apple Music, iTunes, or compatible media software.

If you prefer a graphical workflow, some audio editors and converters can export to ALAC. In those programs, the usual path is File → Open to load the OGG file, then File → Export or Save As and choose ALAC or M4A (Apple Lossless) as the output format.

You can also convert the file on 101convert.com for free, without installing any software.

Notes on quality and compatibility

This conversion is important to understand: OGG Vorbis is usually lossy, while ALAC is lossless. That means converting from OGG to ALAC does not restore audio detail that was already discarded when the OGG file was created. The result will be an ALAC file that preserves the quality of the OGG source, but not true original-master quality.

For best results, convert from the highest-quality source available. If you have the original uncompressed audio, converting that to ALAC is preferable. Also note that ALAC files are often stored in an M4A container, so the output may use the .m4a extension rather than .alac. Compatibility is excellent in Apple software, but some older players may not support ALAC as well as more common lossy formats.
