How to convert OGA to FLAC

  1. Add your .OGA file - drop it in the box above or click to browse.
  2. Convert it to .FLAC in a few seconds.
  3. Download your new .FLAC file.

What to expect

  • Converting a lossy OGA (Vorbis or Opus) to FLAC produces a much larger file without any improvement in audio quality - the lossy compression happened when the OGA was first created.
  • If the OGA already contains FLAC audio inside the Ogg container, the conversion is a simple container swap and is fully lossless with no size penalty.
  • Metadata tags such as artist, title, and album normally carry over unchanged, since both formats use Vorbis comment fields.

Frequently asked questions

Will the audio sound better after converting to FLAC?
No. FLAC preserves exactly what is in the source file, but it cannot recover detail that Vorbis or Opus already discarded during the original encoding.
Why is the FLAC so much bigger than the OGA?
FLAC stores the full audio waveform without lossy compression; a small OGA can easily expand to 20-80 MB as FLAC.
Can I batch-convert a whole folder?
Yes - with ffmpeg in a shell loop, or with foobar2000's built-in batch conversion by adding multiple files to the playlist at once.
Is there any risk of losing audio content during conversion?
No. The decoder reads all audio data from the OGA and FLAC stores it losslessly, so nothing is removed in the conversion step itself.
