PNG to AVIF conversion retains original transparency information while significantly reducing file size. AVIF format supports Alpha channels, perfectly handling transparent background images. Compared to PNG, AVIF can reduce file size by 60-80% while maintaining the same transparency effect, making it ideal for web icons and UI elements.
Transparency conversion notes:
• Fully retains PNG's Alpha channel information
• Supports semi-transparency and gradient transparency
• Automatically optimizes compression of transparent areas
• Maintains edge anti-aliasing effects
Converted AVIF files display exactly the same as original PNGs in supported browsers, with transparent backgrounds perfectly preserved.
