Convert PNG to WebP
PNG is a lossless format, so it preserves every pixel — but that fidelity makes PNG files large, especially for photos and screenshots. WebP keeps PNG's transparency and sharp edges while shrinking the file by 25–40% on average. Converting your PNGs to WebP is one of the single fastest ways to speed up a website without any visible drop in quality.
Set the Format to WebP, then drop your PNG.

Why convert PNG to WebP?
- Cut file size 25–40% versus the same PNG while keeping alpha transparency.
- Faster page loads and better Core Web Vitals (smaller LCP image) — Google rewards this.
- WebP is supported by every modern browser (Chrome, Edge, Firefox, Safari 14+).
- Lossless WebP exists too, so logos and UI assets stay pixel-perfect.
