How to use JPG to AVIF
- Select your JPG images or drag and drop them onto the page. You can also paste an image with Ctrl+V.
- Choose the quality if you want a smaller or sharper AVIF file.
- Click "Convert to AVIF".
- Download your AVIF images, one by one or as a ZIP archive.
AVIF files are often about half the size of a JPG of similar quality. That makes AVIF ideal for image-heavy websites, galleries and online stores that want to load quickly on mobile networks.
Chrome, Edge, Firefox and Safari (since version 16) display AVIF. For very old browsers, keep a JPG version as a fallback.
