OGA to FLAC Converter
Processing entirely on your device — large files may take a moment.
Ogg Audio-Only and FLAC Lossless Audio exist for different jobs: OGA is the audio-only Ogg container — same Vorbis/Opus audio as OGG with a different extension. Convert to FLAC when you want a permanent, lossless archive of your music.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

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 FLAC format
FLAC (Free Lossless Audio Codec, Xiph, 2001) compresses audio to roughly 50–60% of its PCM size and restores every bit on playback — a ZIP for music that also carries proper tags, hi-res support up to 32-bit/655 kHz on paper (24-bit/192 kHz in practice) and full open-source pedigree. It is the archive format of digital music collections.
Support followed maturity: every serious player, modern Android (system-level), most cars and streaming purists' devices handle FLAC natively. Apple resisted for years but iOS 11+ plays it, with the caveat that iTunes/Apple Music syncing still prefers ALAC. The price of losslessness is size — about five times MP3 at comparable quality.
+ Strengths
- ✓Bit-perfect lossless with real compression
- ✓Hi-res capable (24-bit/192 kHz)
- ✓Open, unpatented, tag-native
! Limitations
- −~5× the size of lossy formats
- −Apple syncing prefers ALAC
- −Overkill for casual listening
Why convert OGA to FLAC?
Converting makes sense where the strengths of FLAC meet what OGA cannot give you. Bit-perfect lossless with real compression Meanwhile Extension confuses players less familiar with Ogg One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this OGA to FLAC 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 FLAC?
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 FLAC reduce audio quality?
If FLAC is lossless, the output contains everything the OGA file contains — no further loss is added. If FLAC 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.
