Why convert
Why convert PNG to WEBP?
Cut page weight dramatically
WEBP typically produces files 25–35% smaller than PNG at visually identical quality — sometimes more for photographic PNGs.
Keep transparency
Unlike JPG, WEBP preserves the alpha channel, so logos, icons, and product cutouts still work.
Improve Core Web Vitals
Smaller hero images and thumbnails mean faster LCP and better mobile scores.
