About OGG →

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.

About OPUS →

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.

Frequently Asked Questions

What is the difference between OGG Vorbis and OPUS?

OGG Vorbis is an open-source audio codec from 2000, while OPUS (standardized in 2012) is its modern successor. OPUS achieves the same quality as Vorbis at roughly half the bitrate, making files significantly smaller. Both are royalty-free and open-source.

Will converting OGG to OPUS reduce audio quality?

Technically yes, but usually imperceptible. Converting between lossy formats causes some quality loss. However, OPUS at 192 kbps (our default) is transparent quality—indistinguishable from the source in blind tests. If you have a lossless FLAC source, convert from that instead.

Why convert OGG to OPUS?

Efficiency and compatibility. OPUS offers better compression than Vorbis—same quality at lower bitrates means smaller files. OPUS is also the mandatory codec for WebRTC (Discord, Zoom) and has excellent browser support.

What bitrate does this converter use?

We encode OPUS at 192 kbps VBR (variable bitrate) by default, which provides transparent quality for music. At this bitrate, OPUS rivals 256-320 kbps MP3 quality while being more efficient than OGG Vorbis at equivalent settings.

Which devices and apps support OPUS?

OPUS has broad support: Chrome, Firefox, Edge, Safari 15+, all modern Android phones, VLC, foobar2000, MPV, and most streaming platforms. Apple devices (iOS 17+, macOS Sonoma+) now support OPUS natively.

What happens to metadata?

Preserved! Text metadata (title, artist, album, genre) and cover art transfer automatically. Vorbis comments map directly to OPUS metadata—same tagging system.

I have OGG files from a video game—should I convert to OPUS?

Yes, but check platform support first. OPUS offers superior compression for game audio assets. However, not all game engines support OPUS on all platforms (particularly older consoles). For PC and mobile games, OPUS is an excellent choice with 30-50% smaller files at equivalent quality.

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). Perfect for podcasts, audiobooks, or DJ mixes.

What are the limits for this converter?

Tier	Max File Size	Max Files/Batch	Parallel Processing
Free	50 MB	50 files	3 at once
Pro	500 MB	200 files	6 at once
Business	2048 MB	1000 files	10 at once

Note: File size limits are specific to this converter. Batch and parallel processing limits apply to all images converters site-wide. See all converter limits →

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:

Tier	Daily Limit	Monthly Limit
Free	50 credits/day	—
Pro	—	10,000 credits/month
Business	—	30,000 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.
