What Is AVIF Format?

Maximum Compression: AVIF files are often 50–80% smaller than JPG or PNG.
Superior Image Quality: Sharper details, smoother gradients, and fewer artifacts.
Transparency Support: Like PNG but with far smaller file sizes.
Boosts Website Speed: Faster loading pages improve SEO and user experience.
Bulk Productivity: Convert dozens or hundreds of images in one batch.
