Converting FLAC to OGG gives you a much smaller file. It runs in your browser: nothing is uploaded, there is no queue and no size limit.
What changes when you convert FLAC to OGG
- FLAC is lossless and OGG is not. Expect a much smaller file and a very small, usually invisible, loss of detail. Keep the FLAC if you may edit again.
When to convert, and when not to
Convert to OGG for games and open-source software. Free and open lossy audio.
Keep FLAC for archiving music losslessly. Lossless compression, about half the size of WAV.
How to convert FLAC to OGG
- Drop your FLAC file on the converter above, or click to choose. Several at once is fine.
- Check the options if you need them: audio bitrate.
- Click Convert, then Download. Nothing was sent anywhere, your browser did the work.
Questions
Is my FLAC file uploaded?
No. The conversion runs in your browser with WebAssembly. There is no upload endpoint on this site. You can open your browser's Network tab, or go offline after the page loads, and it still works.
Is there a file size limit?
No fixed one. The limit is your device's memory: a large audio file on a phone is slower than on a laptop, but nothing is rejected for being big.
Is it free?
Yes, without an account, without a daily cap and without a watermark. Your device does the computing, so there is no server bill to pass on.
Will the quality drop?
OGG is lossy, so a little detail is traded for a smaller file. At quality 85 the difference is invisible on photos. For graphics with sharp edges, prefer a lossless format such as PNG.
Can I convert several files at once?
Yes. Drop them all; each is converted in turn and you can download them one by one or as a single ZIP.
Which engine does the conversion?
Media engine (FFmpeg, multithreaded WebAssembly), compiled to WebAssembly and running in your browser, on all your CPU cores when the browser allows it. First use downloads about 31 MB, cached afterwards.
