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.
OPUS is a modern, open-source, royalty-free audio codec developed by Xiph.Org Foundation and IETF, standardized in RFC 6716 in September 2012. It was designed to replace both Vorbis (for music) and Speex (for voice), combining the best of both into a single codec. OPUS achieves exceptional quality at low bitrates—transparent quality at 128 kbps for music, and near-transparent voice at just 32 kbps. It supports bitrates from 6 kbps to 510 kbps and sample rates from 8 kHz to 48 kHz.

OPUS is the mandatory audio codec for WebRTC, making it the native format for video calls (Discord, Zoom, Google Meet, Teams) and voice messaging (WhatsApp, Telegram). It excels at both speech and music, adapting dynamically to content. OPUS files use the Ogg container (.opus extension) and play in all modern browsers (Chrome, Firefox, Edge, Safari 15+), VLC, and most media players from 2015 onward. For streaming, voice chat, podcasts, and any application where quality-per-bit matters, OPUS is the current state of the art.

What are the limits for this converter?
| Tier | Max File Size | Max Files/Batch | Parallel Processing |
|---|---|---|---|
| Guest/Free | 50 MB | 50 files | 3 at once |
| Pro | 2048 MB | 1000 files | 6 at once |

How are credits calculated for this conversion?
Cost: 1 credit per 5 minutes
How it works:
- Files up to 5 minutes: 1 credit
- 6-10 minutes: 2 credits
- 11-15 minutes: 3 credits
- 16-20 minutes: 4 credits
Example: A 10-minute file = 2 credits. 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:
| Tier | Daily Limit | Monthly Limit |
|---|---|---|
| Guest | 100 credits/day | — |
| Free | 100 credits/day | — |
| Pro | — | 12,000 credits/month |
Daily credits (Guest & Free tiers) reset every day at midnight UTC. Monthly credits (Pro) 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 12,000 audio files per month.
