WebP vs PNG: which format is better?

The short answer

Keep WebP when the image is for a website and the browser or CMS accepts it. WebP is designed to keep web images small while preserving good visual quality.

Use PNG when you need editing compatibility, transparent assets, screenshots, slides, documents, or tools that do not recognize WebP.

For modern web delivery, AVIF can also be an option when the destination supports it, but WebP and PNG are still more familiar for everyday workflows.

Why websites like WebP

WebP can store photos and graphics efficiently, which helps websites load faster. That is why images saved from modern websites often arrive as WebP instead of JPG or PNG.

The catch is workflow compatibility. A teacher, client, older document editor, or government upload form may not accept WebP, even if your browser opens it perfectly.

Why people still need PNG

PNG is widely supported in design tools, office documents, school projects, presentation slides, and chat previews. It also handles transparency well, which matters for logos, product cutouts, stickers, and overlays.

The tradeoff is size. A PNG version of a detailed photo can be much larger than the original WebP. If you only need photo compatibility, WebP to JPG may be the better route.

When to convert WebP to PNG

Convert WebP to PNG when you need to edit the image in a design tool, place it in a document, keep transparency, or send it to someone whose software does not understand WebP.

Convert WebP to JPG when the image is a normal photo and the destination wants a widely accepted file type with smaller size than PNG.
