Useful when a project requires a patent-free format, which is common in game engines and open-source software.
MP3, formally MPEG-1 Audio Layer III, was standardised in 1993 after years of work at Fraunhofer IIS. It discards sound the ear is unlikely to notice, which is how a three-minute track fits into a few megabytes instead of thirty. Nothing else comes close to its reach: every phone, browser, car stereo and cheap player made in the last two decades reads it. That universality, not sound quality, is why it is still the safe default today.
Ogg Vorbis came out of the Xiph.Org Foundation in 2000 as a deliberately patent-free answer to MP3. It holds up well against AAC in listening tests and became the standard sound format inside game engines, but it never won the living room or the car.
| MP3 | OGG | |
|---|---|---|
| Released | 1993 | 2000 |
| Developed by | Fraunhofer IIS / MPEG | Xiph.Org Foundation |
| Compression | lossy | lossy |
| Typical bitrate | 128-320 kbit/s | 96-256 kbit/s |
| Three-minute track | 3-7 MB | 3-6 MB |
| Quality ceiling | Good, not transparent | Comparable to AAC |
| Best suited to | Sharing, phones, car stereos | Games, open-source projects |
| Playback support | Universal | Good on desktop, patchy on phones |
Slightly. Both formats are compressed, so decoding and re-encoding costs a little detail. At 192 kbit/s and above the difference is hard to hear on normal equipment, but converting the same file back and forth repeatedly will audibly degrade it.
A normal song finishes in a few seconds. Conversion runs on our server rather than in your browser, so the slow part is usually the upload, not the work itself. Long recordings such as lectures or podcasts take proportionally longer.
Your file is uploaded to our server because the conversion runs there. A cleanup task runs every hour and deletes anything older than an hour, so nothing you upload survives more than about two hours. We do not open your files, we do not keep copies, and no account is needed to use the converter.
