Convert FLAC to OGG
Convert FLAC to OGG on your device. Choose your file, convert, and check the result before sharing.
Drop the flac file
Drag your FLAC onto the page or click to browse. It is read locally, never sent anywhere.
Choose OGG
OGG uses one fixed Vorbis quality setting (about 160 kbps in our test), so there is no bitrate menu. Click Convert to start processing in this tab.
Save the ogg
The finished OGG downloads straight back to your device. Nothing touched a server on the way.
Why convert here, not there
No upload, ever
Audio files are personal. FLAC to OGG here happens inside one browser tab, end to end.
Local conversion
Conversion runs locally after you click Convert. The first audio or video conversion may need to download the converter engine.
No account, no daily cap
No account or daily conversion quota. The per-file cap is 2 GB, and available device memory can impose a lower practical limit.
The two formats, briefly
| FLAC | FLAC uses lossless audio compression. Encoding decoded audio as FLAC does not restore detail already lost in a source recording. | |
|---|---|---|
| OGG | OGG is a container. This converter writes Vorbis audio at a fixed quality setting, not Opus. | |
When you need this
- Use OGG when your receiving app or player does not accept FLAC. This page re-encodes the audio, so keep the original and check the download in that app before replacing it.
FLAC vs OGG: what changes
| FLAC | OGG | |
|---|---|---|
| Kind | Audio | Audio |
| Compression | Lossless audio compression | Vorbis audio output here |
| Typical size | Depends on the file and encoding settings. | Measure the exported file; it may be larger. |
| Opens on | Check the source in your app and browser. | Check the downloaded file in the receiving app. |
| Best for | Keep the original as your source. | OGG workflows, subject to the limits below. |
Keep the original. Compare the exported file before sharing or replacing it.
Tested on this tool
On 3 November 2026 we ran a synthetic test file through this converter: a 10-second, 44.1 kHz mono FLAC holding a 520 Hz tone, 129,950 bytes. The output was a 24,326-byte OGG (Vorbis) file - same 44.1 kHz sample rate, same mono channel, 10.0 seconds - that decoded cleanly, with the 520 Hz tone still present when we measured it.
- Sample rate and channel count were preserved in this test.
- Vorbis is lossy, and a pure tone compresses unusually well. Music will not shrink the same way, and some detail is discarded in the re-encode.
One synthetic tone is not every FLAC. Real music, higher sample rates and multichannel audio were not part of this test, and a phone browser can hit memory limits before a desktop does.
Good to know
- The encoder uses fixed Vorbis quality 5. The bitrate varies with the audio; a quality menu does not select a fixed bitrate for this path.
- First use downloads the audio/video engine (about 30 MB). The input cap is 2 GB, but available browser memory can run out below that.
