Halve your image weight with AVIF
AVIF is one of the most efficient image formats available on the web today. At the same visual quality it often produces files about 50% smaller than JPG and noticeably smaller than WebP, which is a big speed gain for image-heavy blogs, news sites and online shops.
Page speed and SEO
Lighter images mean faster loading, a lower Largest Contentful Paint (LCP) and less data usage for mobile visitors, which benefits both user experience and search rankings.
Conversion details
AVIF encoding is CPU-intensive, so conversion runs on our server and your files are deleted automatically afterwards. To support very old browsers, serve a JPG fallback alongside AVIF on your site.
How to use JPG to AVIF Converter
- Upload your JPG or JPEG photos.
- Start the conversion.
- AVIF files are created on the server; watch the live progress.
- Download the AVIF files and upload them to your site.

FAQ
Which browsers support AVIF?
Chrome, Edge, Firefox, Opera and Safari 16 or later support AVIF.
Should I use AVIF or WebP?
AVIF usually produces smaller files; WebP encodes faster and is supported on slightly older devices. For the best result, serve both.
Why does conversion take a few seconds?
AVIF encoding needs far more computation than JPG, so jobs are queued and processed on the server.
