Who converts PNG to WebP
Website logos and icons
PNG logos with transparent backgrounds are a perfect WebP conversion target. Transparency is preserved and file size drops dramatically.
UI screenshots and product images
Screenshots taken as PNG (often large because of lossless format) compress well to WebP without the blocky artefacts you get from JPEG.
Game and app assets
Mobile and web apps with sprite sheets or UI assets as PNG can reduce asset bundle size significantly by converting to WebP.
E-commerce product images
Product images with removed backgrounds (PNG with transparency) are widely used in e-commerce. WebP reduces page weight and speeds up product pages.
WordPress media library
WordPress 5.8+ supports WebP uploads. Replacing large PNG assets with WebP equivalents can shave megabytes off page weight across your entire site.
Core Web Vitals improvement
LCP (Largest Contentful Paint) is heavily influenced by image file size. Converting PNG hero images to WebP is one of the fastest wins available.

How the conversion works
Your PNG is decoded by the browser and drawn to an HTML Canvas element. The canvas is then exported using the browser's built-in WebP encoder. The alpha channel (transparency) is preserved throughout this process. All processing happens locally — your file never leaves your browser.
