PNG, JPG, or WebP: Which Image Format Should You Use?

Choosing an image format is mostly about the job the image needs to do. A screenshot, a product photo, and a transparent logo should not always use the same format.

Choose PNG when clarity matters

PNG is a good fit for screenshots, UI captures, diagrams, and graphics with sharp edges. It also supports transparency. The tradeoff is file size: PNG can be much larger than JPG or WebP for photos.

Choose JPG for photos and broad compatibility

JPG is still the safest format for photos when a website, email client, or upload form needs broad support. It uses lossy compression, so very low quality settings can create visible artifacts, but the file size is usually much smaller than PNG.

Choose WebP for smaller web images

WebP often gives smaller files than JPG or PNG at similar visual quality. It is useful for websites and modern apps, but some older tools and workflows still reject it. If a form does not accept WebP, convert it to JPG or PNG first.

A simple rule

Use PNG for transparency or crisp interface graphics, JPG for photos and compatibility, and WebP for modern web delivery when the destination accepts it.
