About JPG to AVIF Converter

AVIF is the most efficient image format available today — delivering 40–50% smaller files than JPG at equivalent quality, outperforming even WebP. It is supported in Chrome, Edge, Firefox, and Safari 16+. Converting JPG images to AVIF is the highest-ROI format switch you can make for modern web performance.

How the JPG to AVIF Converter works

VIPToolkit's JPG to AVIF converter runs entirely in your browser using the HTML5 Canvas API. Upload your JPG and download the AVIF instantly — no server upload, no account, no file size limit beyond device memory.

Note: AVIF encoding requires a Chromium-based browser (Chrome or Edge). Firefox and Safari can display AVIF but do not yet support encoding via the Canvas API — use JPG to WebP on those browsers instead.

Common uses for JPG to AVIF conversion

Common use cases: converting hero images and product photos to AVIF for maximum web performance, optimising images before uploading to a modern CMS, and replacing JPG assets in a web project with the most efficient format currently available. Need to go back? Use the AVIF to JPG converter.

Frequently Asked Questions

AVIF typically produces 40–50% smaller files than JPG — noticeably better than WebP's 25–35% — at similar visual quality, when browser support allows.

AVIF encoding via the Canvas API is currently only supported in Chromium-based browsers (Chrome, Edge). Firefox and Safari can display AVIF but not encode it — use JPG to WebP instead on those browsers.

AVIF needs a browser released in the last few years (Safari 16+, Chrome 85+, Firefox 93+). For guaranteed universal compatibility, JPG remains the safer choice.
