Preserves Transparency
Unlike JPG, AVIF supports alpha transparency. Convert transparent PNGs (logos, icons, UI elements) to AVIF and keep transparency while shrinking file size.
Faster Website Loading
Smaller image files mean faster page loads. Convert PNG assets to AVIF to improve LCP scores, reduce bounce rates, and boost SEO rankings.
Reduced Bandwidth Costs
Cut CDN and hosting bandwidth by up to 50% by serving AVIF instead of PNG. Significant savings for high-traffic websites and image-heavy applications.

Follow these expert tips to maximize quality and efficiency when converting PNG to AVIF.
Use Lossy for Photos
For photographic PNG content, lossy AVIF at quality 60 typically produces files 50-70% smaller with no visible quality difference.
Use Lossless for Graphics
For sharp graphics, text, or screenshots, use lossless AVIF mode. It still produces smaller files than PNG while preserving every pixel.
Transparency Is Supported
AVIF fully supports alpha transparency. Your transparent PNG logos and icons will remain transparent after conversion to AVIF.
Provide PNG Fallback
Use the HTML <picture> element to serve AVIF first with PNG fallback. This ensures older browsers still display your images correctly.
