How to convert images to AVIF
AVIF is the most efficient image format in wide use today, routinely beating WebP and JPEG. OctoSqueeze converts your images to AVIF and lets you serve it to supporting browsers with a WebP or JPEG fallback for the rest.
Why AVIF matters
Lighter images load faster, improve your Core Web Vitals, and save bandwidth for you and your visitors. On mobile especially, a 2 MB hero image can be the difference between a bounce and a conversion.
AVIF vs. WebP
AVIF goes smaller, but WebP still has the widest support. Export both and serve AVIF first with a WebP fallback to cover every visitor.
Do it at scale
Converting one image is easy. Converting thousands is what our REST API is for — one call returns an optimized file (or a CDN URL) in any format you need.
