FLAC to OGG converter
Convert a FLAC into an OGG right here on the page. OGG is a free audio format that sounds better than MP3 at the same file size, and the gap widens as files get smaller. The usual reason to do it is size, because OGG is far smaller for this sort of thing. Your file never leaves your computer.

How to convert FLAC to OGG
- 1 Drop your FLAC .flac file onto the page, or click to browse for it.
- 2 Set the quality, or leave the default, which keeps the file small without anything showing.
- 3 Convert. The work happens on your own machine, so how long it takes depends on your computer and the file.
- 4 Download the OGG, or add more files and do the whole set in one go.
Why convert FLAC to OGG
- OGG files come out much smaller, which is the difference between a page that loads straight away and one that keeps people waiting.
- Patent free and open, with no licensing to worry about.
- Better quality than MP3 at the same file size.
- Web audio where Safari is not the only target.
- FLAC: much larger than MP3, AAC or Opus.
FLAC compared with OGG
How the two formats differ on the things that decide whether a conversion is worth making.
| Property | FLAC | OGG |
|---|---|---|
| File extension | .flac | .ogg |
| Compression | Lossless | Lossy |
| Typical file size | Larger | Smaller |
| Introduced | 2001 | 2000 |
Quality and what changes
This is the step where information is discarded, and it cannot be undone by converting back later. OGG throws away detail the eye is least likely to notice, which is invisible at sensible settings and shows as blocking around sharp edges and text when pushed hard. Keep the FLAC as your master and treat the OGG as a delivery copy.
- One OGG limitation to keep in mind: less consistent support in consumer devices.
Questions about FLAC to OGG
Is my FLAC file uploaded anywhere?
No. The whole thing runs inside the browser tab you already have open. Your FLAC is read straight from your own disk, converted on your machine and handed back as an OGG. Nothing is sent anywhere, nothing is stored and there is no account.
Is there a file size limit?
There is no server-side limit because no server sees the file. The real ceiling is your device memory, since the input and the output both have to fit in the tab. A few hundred megabytes is usually fine on a desktop machine and considerably less on a phone.
Can I convert several FLAC files at once?
Yes. Add as many as you like and they are processed one after another, then offered as separate OGG downloads or as a single ZIP. Speed depends on your own processor rather than on a queue.
Does the converter work offline?
Yes, after the page has loaded once. The engine is cached by the browser, so you can disconnect, reload and keep converting. That falls out of doing the work locally rather than being a separate mode you switch on.
