QOI vs AVIF: Format Comparison

Key differences between the two formats

Feature	QOI	AVIF
Compression	Lossless, simple RLE-based	Lossy or lossless, AV1-based
File size	Moderate (better than PNG)	Extremely small (best compression)
Encoding speed	Very fast (microseconds)	Slower (complex codec)
Browser support	Limited (manual decode)	Growing (Chrome, Firefox, Safari)
Use case	Fast prototyping, embedded systems	Web images, production apps
Color depth	8-bit RGBA	8/10/12-bit, HDR support
Animation support	No	Yes (AVIF sequences)
Transparency	Yes (alpha channel)	Yes (alpha channel)

When to Convert

Common scenarios where this conversion is useful

Web optimization for modern browsers

AVIF offers 50% smaller file sizes than JPEG with comparable quality. Converting QOI prototypes to AVIF makes them production-ready for bandwidth-conscious web applications and modern browser environments.

Transitioning from prototype to production

QOI is ideal for rapid prototyping due to its encoding speed, but AVIF is better for production deployment. This conversion bridges the gap between fast development and optimized delivery.

Reducing storage and bandwidth costs

AVIF's superior compression dramatically reduces CDN bandwidth and storage costs compared to QOI. Ideal for image-heavy applications, galleries, and content delivery platforms serving millions of images.

Next-gen image delivery

AVIF is the future of web images. Converting QOI assets to AVIF ensures compatibility with the latest image optimization techniques, improving page load times and user experience across modern web platforms.

Who Uses This Conversion

Tailored guidance for different workflows

Web Developers

Convert QOI prototypes to production-ready AVIF for modern web applications
Optimize image delivery by leveraging AVIF's superior compression for bandwidth savings

Always serve AVIF with fallbacks using the picture element for older browser support

Test AVIF quality settings to balance file size and visual fidelity for your use case

Game Developers

Convert QOI assets (used for fast loading in-game) to AVIF for web-based game marketing materials
Transition texture prototypes from QOI to AVIF for optimized web galleries and press kits

Keep QOI for runtime use in engines where decoding speed matters, use AVIF for web delivery

Verify color accuracy after conversion, as lossy AVIF may introduce subtle color shifts

Frequently Asked Questions

What is QOI and why convert it to AVIF?

QOI (Quite OK Image) is a fast, simple lossless format designed for speed. AVIF is a next-generation format with cutting-edge compression. Converting QOI to AVIF trades encoding speed for file size, making images production-ready for the web.

Will the AVIF be smaller than the QOI?

Yes, significantly. AVIF typically achieves 30-50% smaller file sizes than QOI at comparable quality levels. AVIF's AV1-based codec is far more sophisticated than QOI's simple RLE compression.

Does AVIF support transparency like QOI?

Yes. Both QOI and AVIF support alpha channels. Transparency is preserved during conversion, making AVIF suitable for logos, icons, and graphics with transparent backgrounds.

Which browsers support AVIF?

AVIF is supported in Chrome 85+, Firefox 93+, Safari 16+, and Edge 121+. Browser support is growing rapidly. For older browsers, consider serving fallback formats like WebP or JPEG.

Is this conversion lossy or lossless?

By default, this converter uses AVIF's lossy mode for maximum compression. While QOI is lossless, converting to lossy AVIF produces dramatically smaller files with minimal visible quality loss. Lossless AVIF is possible but less common.

Why would I use QOI instead of AVIF?

QOI encodes in microseconds, making it ideal for real-time applications, game engines, and embedded systems where speed matters more than file size. AVIF is better for web delivery where compression is critical.

Are my files sent to a server?

No. ChangeThisFile processes everything in your browser using the Canvas API. Your images are never uploaded or transmitted anywhere. The conversion is instant and completely private.

Can AVIF handle HDR images?

Yes. AVIF supports 10-bit and 12-bit color depth, making it excellent for HDR images. QOI is limited to 8-bit RGBA. Converting to AVIF doesn't add HDR data, but AVIF is capable of storing it if the source has it.

Should I use AVIF for all my web images?

AVIF is excellent for photos, hero images, and graphics where compression matters. For simple graphics, SVG may be better. Always serve AVIF with fallbacks (WebP, JPEG) for older browsers using the picture element.

Does this conversion preserve EXIF data?

No. QOI doesn't support EXIF metadata, and this browser-based conversion doesn't transfer metadata between formats. If metadata preservation is critical, use a server-side tool designed for that purpose.
