What is AVIF?
AVIF (AV1 Image File Format) is a modern image format that typically produces files 30–50% smaller than JPEG and 20–30% smaller than WebP at equivalent visual quality. Every modern browser — Chrome, Edge, Firefox, Safari 16+, and mobile browsers — can display AVIF images.
Why use it on your site?
- Smaller images mean faster page loads, especially on mobile.
- Faster pages rank better in Google and convert more visitors.
- Ohio hosting customers can drop the result straight into WordPress — it works as a standard image.
How this tool works
Everything runs in your browser. Your images never get uploaded to a server, so there’s nothing to wait on and no privacy concern. We use the browser’s built-in AVIF encoder (the same one Chrome and Firefox use internally) so output is consistent with what your visitors’ browsers would produce.
