OGA to ALAC Converter
Processing entirely on your device — large files may take a moment.
Convert ALAC to FLAC for non-Apple players, or MP3 for sharing. If your files are still in OGA format, this page is the shortcut: OGA is the audio-only Ogg container — same Vorbis/Opus audio as OGG with a different extension.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the OGA format
OGA is the Ogg container's audio-only extension: the same Vorbis (or Opus/FLAC) stream as an OGG file, renamed to signal "this is music, not video". Wikipedia's audio files and old game rips commonly use it.
Functionally it is an OGG — and it inherits the same hardware-support lottery. Converting OGA to MP3 ends the guessing game on phones, car stereos and anything without an Ogg decoder.
+ Strengths
- ✓Open, royalty-free Vorbis audio
- ✓Identical quality to OGG
! Limitations
- −Extension confuses players less familiar with Ogg
- −Same hardware gaps as OGG
About the ALAC format
ALAC (Apple Lossless Audio Codec) is Apple's FLAC equivalent: bit-exact lossless compression inside an MP4 container, opened-source in 2011 and now native on every Apple device and most server-side pipelines. It is what iTunes Store sells as "lossless" and what iPhone recordings encode to by default.
For non-Apple players FLAC is the safer target, and conversion is sample-exact in both directions — the decode is handled by ffmpeg's native ALAC decoder without any Apple runtime.
+ Strengths
- ✓Native on every Apple device
- ✓Open source since 2011
- ✓Reasonable sizes inside MP4
! Limitations
- −Outside Apple ecosystems FLAC wins
- −Slightly worse ratios than FLAC
- −Confusing .m4a extension doubles as lossy

Frequently asked questions
Is this OGA to ALAC converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for OGA to ALAC?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Can I convert a whole folder of OGA files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
Will converting OGA to ALAC reduce audio quality?
If ALAC is lossless, the output contains everything the OGA file contains — no further loss is added. If ALAC is lossy, one recompression pass is unavoidable; the quality slider controls how much. Loss that already happened in the source file can never be undone by converting.
