OGG (Ogg Vorbis) is an open-source, royalty-free lossy audio codec developed by the Xiph.Org Foundation, with Vorbis 1.0 finalized in July 2002 as a patent-free alternative to MP3. Technically, "Ogg" is the container format while "Vorbis" is the audio codec, but "OGG" commonly refers to Vorbis-encoded audio files. Vorbis achieves compression ratios of 8:1 to 10:1 using a quality scale from -1 (lowest) to 10 (highest), and generally outperforms MP3 in blind listening tests at equivalent bitrates—particularly at 128 kbps and below.

OGG supports sample rates up to 192 kHz and up to 255 audio channels, making it technically versatile. Its main strength is open licensing—it's the standard audio format for video games (Unity, Unreal Engine), Spotify's internal format, and widely used in open-source software. The tradeoff is hardware support: while software players universally support OGG, many hardware devices (car stereos, standalone MP3 players) do not. For gaming audio, podcasts in open-source ecosystems, or any project avoiding patent concerns, OGG is the pragmatic choice.

MP3 (MPEG-1 Audio Layer III) revolutionized digital audio when it was standardized in 1993 by the Fraunhofer Society. Using psychoacoustic compression, MP3 removes audio frequencies that humans typically cannot perceive, achieving 10:1 compression or better while maintaining excellent subjective quality. MP3 supports sample rates from 8-48 kHz and 16-bit audio. At 256 kbps, most listeners cannot distinguish MP3 from the original source in blind tests.

MP3 remains the most universally compatible audio format, supported by every music player, smartphone, computer, and web browser. While newer codecs like AAC and Opus offer marginally better compression efficiency, MP3's ubiquitous support makes it the safest choice for sharing audio. The format's patents expired in 2017, making it completely free to use without licensing concerns.

Frequently Asked Questions

What is the difference between OGG and MP3?

OGG Vorbis is an open-source, royalty-free audio format that typically provides better quality than MP3 at the same bitrate. MP3 is the universal standard with near-complete device support. Both are lossy formats, but OGG is less widely supported on consumer devices.

Will converting OGG to MP3 reduce audio quality?

Yes. Converting between lossy formats (lossy-to-lossy) means some additional quality loss. However, we encode at 320 kbps MP3 (maximum quality) to preserve excellent quality. The difference is typically negligible for most listeners. If you have a lossless source, convert from that instead.

Why would I convert OGG to MP3?

Compatibility. OGG files don't play on all devices—especially older MP3 players, car stereos, and some smartphones. MP3 is universally supported. Converting to MP3 ensures your audio plays everywhere. Need the reverse for game development? Convert MP3 to OGG.

What MP3 settings do you use?

We encode at 320 kbps MP3 (maximum quality) using the high-quality LAME encoder. This is the highest standard MP3 bitrate, ensuring excellent quality for the format.

Where is OGG commonly used?

OGG Vorbis is popular in video games (many game engines use OGG for audio), open-source software, and platforms that prefer royalty-free formats. Spotify also uses OGG Vorbis for streaming.

What happens to metadata?

Yes, it transfers. Text metadata (title, artist, album, genre) and cover art transfer automatically. Vorbis comments are automatically mapped to ID3 tags during conversion.

How long can my audio files be?

Duration limits depend on your plan: Guest/Free: 120 minutes, Pro: 600 minutes (10 hours), Business: 3000 minutes (50 hours). This accommodates everything from game audio to full soundtracks and podcasts.

How are credits calculated for this conversion?

Cost: 1 credit per 5 minutes

How it works:

  • Files up to 5 minutes: 1 credit (minimum)
  • 6-10 minutes: 2 credits
  • 11-15 minutes: 3 credits
  • 16-20 minutes: 4 credits

Example: A 10-minute file = 1 credit. A 180-minute (3h) audiobook = 36 credits.

Why per-minute? Audio conversion time scales with content duration, not file size. Longer audio requires proportionally more processing.

What are my daily and monthly credit limits?

Credit allocations vary by account tier:

TierDaily LimitMonthly Limit
Free50 credits/day
Pro10,000 credits/month
Business30,000 credits/month

Daily credits (Free tier, including guests) reset every day at midnight UTC. Monthly credits (Pro & Business) reset on your billing cycle date.

Note: With 1 credit per 5 minutes, audio files under 5 MB cost 1 credit each. Pro users can convert 10,000 audio files per month.
