Use cases for sample AVIF files

Testing AVIF support in image upload and processing pipelines
Verifying AVIF-to-WebP/JPG fallback with <picture> tag
Benchmarking AVIF vs WebP vs JPEG file sizes and quality
Testing browser compatibility for AVIF rendering
Verifying transparent AVIF alpha channel support
Testing CDN image optimization and AVIF auto-negotiation

AVIF vs WebP vs JPEG — Compression comparison

Feature	AVIF	WebP	JPEG
Lossy compression	~50% smaller	~30% smaller	baseline
Lossless compression	Best	Good	N/A
Transparency	Yes	Yes	No
HDR / Wide gamut	10/12-bit	8-bit only	8-bit only
Browser support	92%+	96%+	100%
Encoding speed	Slow	Fast	Fast

Browser support

Supported: Chrome 85+, Firefox 93+, Safari 16+, Edge 121+, Opera 71+, Android Browser, Samsung Internet

Not supported: IE 11, older Safari (15 and below), older Firefox (92 and below)

Use the <picture> tag with WebP and JPG fallbacks for maximum compatibility.

How to serve AVIF with fallback

<picture>
  <source srcset="image.avif" type="image/avif">
  <source srcset="image.webp" type="image/webp">
  <img src="image.jpg" alt="Description">
</picture>

Browsers pick the first supported format. AVIF-capable browsers load .avif, others try .webp, and the rest fall back to .jpg. No JavaScript needed.

Frequently Asked Questions

What is AVIF?

AVIF (AV1 Image File Format) is a modern, open-source image format based on the AV1 video codec. Developed by the Alliance for Open Media (Google, Apple, Mozilla, Netflix), AVIF delivers up to 50% better compression than JPEG while supporting transparency, HDR (10/12-bit), wide color gamuts, and animation. It is royalty-free and supported by Chrome, Firefox, Safari, and Edge.

AVIF vs JPG — Which is better?

AVIF is significantly better than JPG (JPEG) for file size: a typical AVIF image is 50% smaller at the same visual quality. AVIF also supports features JPEG lacks entirely — transparency, HDR, 10/12-bit color depth, and wide gamut (Display P3). The tradeoff: AVIF encoding is slower and browser support is 92% vs JPEG's 100%. For web use, serve AVIF with a JPEG fallback via the <picture> tag.

AVIF vs WebP — Which should I use?

AVIF offers ~20% better compression than WebP at the same quality. However, WebP has slightly broader browser support (96% vs 92%) and much faster encoding. Best practice: serve both with <picture> tag — AVIF first, WebP second, JPEG last. Most CDNs (Cloudflare, Imgix, Cloudinary) handle this automatically via content negotiation.

Does AVIF support transparency?

Yes. AVIF supports a full alpha channel for transparency, similar to PNG and WebP. Unlike PNG however, AVIF compresses transparent images much more efficiently. Our sample-transparent.avif demonstrates AVIF alpha channel support — download it to test transparency handling in your application.

Why is AVIF encoding so slow?

AVIF uses the AV1 codec which was designed for maximum compression, not speed. Encoding a single image can take 5–20x longer than JPEG or WebP. This makes AVIF ideal for pre-generated assets (static sites, CDNs) but less suitable for real-time encoding. Hardware AV1 encoders are steadily improving this gap.

How do I convert images to AVIF?

CLI: avifenc input.png output.avif (libavif). Node.js: sharp('input.jpg').avif({ quality: 50 }).toFile('output.avif'). Online: squoosh.app. CDNs like Cloudflare, Imgix, and Cloudinary can auto-convert to AVIF based on the Accept header.
