JPG to AVIF, without leaving your browser.
AVIF is the most efficient image format your visitors' browsers can display. Convert JPG images to AVIF locally in your browser and cut file sizes far beyond what WebP achieves.
Smaller files
AVIF reaches the same visual quality at roughly 30–50% less than WebP — the strongest compression available in every modern browser.
Web-ready output
Resize, crop and cap the file size in the same run. The result is ready for your site, store or CMS — no second tool needed.
Private by design
The conversion runs in your browser via the Canvas API. No server ever sees your images, and EXIF, GPS and camera data are stripped on the way.
How it works
Drop your JPG images
Drag & drop, browse or paste from the clipboard. Up to 30 files per batch — all processed in parallel.
Pick your settings
Output format is preset to AVIF. Adjust quality, dimensions or cap the file size — or just hit optimize.
Download the AVIF files
Grab each file individually or take the whole batch as a single ZIP. Compare before and after with the slider.
