About PNG to WebP Conversion
WebP is a modern image format developed by Google that produces significantly smaller files than PNG. A lossless WebP image is typically 26% smaller than the same PNG. A lossy WebP at quality 85 is often 60–80% smaller while remaining visually indistinguishable from the original.
For web use, switching from PNG to WebP is one of the fastest ways to improve page load speed. Google uses WebP file size as a signal in Core Web Vitals, so converting your images can directly improve your Largest Contentful Paint (LCP) score.
Unlike converting to JPG, converting PNG to WebP preserves transparency. If your PNG has a transparent background, the WebP output will too. Set quality to 85–90% for the best balance of file size and visual quality, or go lower for icons and graphics where detail matters less than speed.
