PNG vs WebP: Which Image Format Should You Use in 2026?

PNG vs WebP: Which Image Format Should You Use in 2026? PNG has been the go-to format for lossless web images since 1996. WebP, developed by Google and released in 2010, was built to replace it — offering smaller files with comparable quality. The PNG vs WebP debate used to hinge on browser support, but that argument is over. Every modern browser ships with full WebP support. So the real question is: should you still use PNG at all? Yes — sometimes. Here is exactly when each format wins, backed by real file size comparisons, so you can make the right call for your project.
