Frequently asked questions
Is this OGG to FLAC converter free?+
Yes, with no watermark, no account, and no daily limit.
Is my audio file uploaded anywhere?+
No — conversion runs locally using your browser's own built-in media codecs, entirely inside your browser tab.
Will I lose audio quality?+
Converting between compressed formats can lose a small amount of quality; converting to a lossless format like WAV or FLAC won't.
Is there a maximum file size?+
There's no fixed file-size limit since nothing is uploaded to a server. Processing time scales with the track's length rather than a hard cutoff.
How do I convert OGG to FLAC?+
Drop your OGG file into the box above — it's decoded and re-encoded as FLAC automatically, with a download ready in seconds.
About OGG and FLAC
What is OGG?
OGG (usually carrying Vorbis audio) is a royalty-free, open compressed format popular in games and open-source software.
Full OGG format guide →What is FLAC?
FLAC is a lossless compressed audio format — same audio quality as WAV, but roughly half the file size thanks to genuine (not perceptual) compression.
Full FLAC format guide →The short version: FLAC gives you bit-perfect, lossless audio, which helps once you run into OGG's biggest limitation: less common in mainstream consumer devices than MP3 or AAC. It's a natural move when your audio is headed toward archiving music at full quality.
How it works
- 1
Drop your file in
Drag your audio onto the box above, or click it to browse — there's no account to create and no upload to wait on.
- 2
Pick your settings
The output format is already set for this page — just adjust any extra options shown, if there are any.

Download the result
Your browser processes everything locally and hands you a download link the moment it's done — nothing was ever sent to a server.
Is it private?
Everything happens locally, inside this browser tab. Your audio is read from disk, processed with WebAssembly running on your own device, and handed back to you as a download — it's never transmitted anywhere, so there's nothing to intercept and nothing stored on a server.
Common use cases
- Archiving music at full quality
- Audiophile listening
- Prepping a podcast episode for a hosting platform
- Fitting a voice memo under a messaging app's size limit

About OGG files+
OGG (usually carrying Vorbis audio) is a royalty-free, open compressed format popular in games and open-source software.
The Xiph.Org Foundation created Ogg as a free, patent-unencumbered container specifically so that open-source and community software wouldn't be tied to the licensing terms attached to formats like MP3. Most commonly it carries Vorbis-encoded audio, which holds up well against MP3 and AAC in blind listening tests at the same bitrate. Because there's no licensing fee attached, it became a natural fit for video game audio and open-source media players, even though it never reached the same mainstream adoption as MP3 on consumer devices.
How to open a OGG file
Opens readily in VLC Media Player, Most web browsers. For real editing, use Audacity (free).
Good for
- no licensing fees or patent concerns
- solid compression efficiency
Watch out for
- less common in mainstream consumer devices than MP3 or AAC
About FLAC files+
FLAC is a lossless compressed audio format — same audio quality as WAV, but roughly half the file size thanks to genuine (not perceptual) compression.
FLAC (Free Lossless Audio Codec) was built by the Xiph.Org Foundation to solve a specific problem: WAV files are lossless but enormous, while MP3 and AAC are small but throw away audio data permanently. FLAC compresses audio the way a ZIP file compresses text — genuinely, reversibly, with zero data loss — typically landing at 50–60% of the original WAV size. That makes it the go-to format for anyone archiving music at full fidelity, at the cost of files still noticeably larger than a lossy MP3 or AAC.
How to open a FLAC file
Opens readily in VLC Media Player, Most modern phones and media players. For real editing, use Audacity (free).
Good for
- bit-perfect, lossless audio
- smaller than WAV for the same quality
Watch out for
- not supported by every device, though support is broad among dedicated audio players
