WebP vs PNG: which is better for web images?
A clear, practical comparison with a straight answer.
Use WebP for images on your own website to cut load times, ideally with a PNG fallback for very old clients. Use PNG when you need a file that opens perfectly in every editor, email and app without question.
These two formats compete for the same job: crisp graphics, logos and screenshots with transparent backgrounds. PNG has done it faithfully for decades. WebP does it in a smaller file, if everything downstream supports it.
For a website you control, WebP almost always wins on speed. For a file you are handing to someone else, PNG's total compatibility can still be worth the extra kilobytes.

Frequently asked questions
Is WebP always smaller than PNG?
For most graphics, yes, lossless WebP beats PNG on size. The gap is smaller for very simple images.
Should I replace all my PNGs with WebP?
On a website, serving WebP with a PNG fallback is a good balance of speed and compatibility. For files you send to others, PNG is the safer default.
