A PRACTICAL IMAGE GUIDE
Balance AVIF file size against encoding time
AVIF is a useful format to try when your destination accepts it. The quality control can reduce file size, but encoding can take longer than JPEG or WebP and every input has different results.
How to optimize an AVIF image
Upload the AVIF, keep the original format, and choose Smart for a first comparison. Try a lower quality or smaller dimensions if it is still too large. Check the resulting detail before replacing a published asset.
Choose compatibility for the destination
Keep AVIF for a site or application that accepts it. Choose JPEG for a form that requires JPG. This build creates still AVIF output; animated input converted to AVIF uses the first frame.
GOOD TO KNOW
About this image tool
Understand the result before choosing your download.
Does a smaller AVIF guarantee a faster webpage?
Reducing transferred bytes can help, but page speed also depends on image dimensions, hosting, caching and the rest of the page. This tool does not measure your site's performance.
Can I compare AVIF when my browser cannot display it?
The comparison tool requests PNG previews from the service. These are scaled previews, while the download remains the chosen output format.
