Convert Ogg Vorbis to FLAC
We turn Ogg Vorbis into FLAC right in your browser — the file never goes to a server.
What you will lose
Nothing to lose, and nothing to gain: {to} keeps exactly what {from} hands over, and the file grows several times over.

Ogg Vorbis
Good at
- A free format with no licensing fees
- Better than MP3 at the same size
- Tags and multichannel audio are there
Awkward about
- Less widely supported than MP3

- Rare in the Apple world
Use it when
- Sound in a game or an app where we choose the format
- Freedom from licensing fees matters
- You want an MP3 replacement without losing quality
FLAC
Good at
- Lossless, yet half the size of WAV
- Proper tags and cover art
- Handles multichannel audio
Awkward about
- Still heavy for sending and streaming
- Some consumer devices will not open it
- The point only shows on good equipment
Use it when
- A home collection you do not want to re-encode
- An archive of recordings — a master for later
- You need the original quality with tags
Common questions
- Does the file get uploaded to a server?
- Yes, this pair needs the server: browsers cannot encode that format. The file and the result are deleted within a couple of hours and never shared.
- Will surround sound survive?
- Yes, FLAC carries more than two channels — 5.1 stays 5.1.
- Can I get the original quality back afterwards?
- Nothing is lost, but nothing is gained either. FLAC stores exactly what Ogg Vorbis hands over, including the gaps Ogg Vorbis left behind when it compressed. No tool can bring those back, and the file grows several times over. This conversion makes sense for editing, not for quality.
- How many files, and how large?
- Up to 10 files at a time, 200 MB each. No sign-up, no watermarks.
