Convert OGG to ALAC — Free Online Converter

OGG Vorbis is Xiph.org's open-source lossy codec with excellent quality characteristics. ALAC (Apple Lossless Audio Codec), open-sourced by Apple in 2011, provides lossless compression within the M4A container and plays natively on every Apple device. ALAC achieves roughly 40-60% compression compared to raw PCM while preserving every audio sample bit-for-bit.

Converting OGG to ALAC decodes the Vorbis audio to PCM and re-encodes it losslessly using ALAC. The result is a file that preserves the full decoded quality of your OGG source in Apple's native lossless format, ready for the entire Apple ecosystem.

Apple devices cannot play OGG Vorbis natively. ALAC is Apple's native lossless format with hardware-accelerated decoding on iPhone, iPad, Mac, HomePod, and Apple Watch. Converting OGG to ALAC ensures your audio is playable across all Apple hardware while preserving every decoded sample.

ALAC also provides a lossless safety net for future transcoding. If you later need AAC, WAV, or any other format, the ALAC file preserves the full decoded quality of the OGG source without further generation loss. The M4A container supports rich metadata including album art, lyrics, and chapter markers.
