Sample AVIF Files — Download Next-Generation Web Image Test Files
AV1 Image File Format · .avif · MIME type image/avif
Download a sample AVIF file to test the newest mainstream web image format: AVIF wraps a still AV1 frame in a HEIF container and typically produces files 50% smaller than JPEG and 20% smaller than WebP at the same quality. Chrome, Firefox, Safari 16+ and Edge all display it, and image CDNs increasingly serve it first.
Because it is new, tooling gaps are common — older ImageMagick builds, many PHP GD installs and most email clients cannot decode AVIF. These files let you check whether your stack can, before a user finds out.

Frequently asked questions
AVIF vs WebP — which should I use?
AVIF gives smaller files and better quality at low bitrates, especially for photographs; WebP encodes much faster and has broader tool support. The common approach in 2026 is <picture> with AVIF first, WebP second and JPG as the fallback — and to let an image CDN generate all three.
Are these AVIF files safe to download?
Yes. Every file is generated by our own open script from scratch — nothing is scraped or user-uploaded — and contains no scripts, macros or executables. The SHA-256 of each file is published on this page so you can verify what you received.
Can I use the sample AVIF files commercially?
Yes. They are free for any purpose, including commercial products, test suites, demos and redistribution, with no attribution required. There is nothing to license and no one to ask.
Can I hotlink these files or use them in CI?
Yes. Every link is a stable direct URL over HTTPS with Access-Control-Allow-Origin: * and long cache headers, so curl, wget, fetch() and test runners can pull them directly. A JSON index of every file is linked from each page (see the command-line section).
