Best Image Format for Websites

There is no single best image format for every website image. The right choice depends on whether the image is a photo, graphic, logo, screenshot, or interface asset, and whether page speed matters more than editing flexibility.

Quick answer

For most website photos, WebP is a strong default because it often reduces file size. Use PNG for graphics and screenshots that need a lossless workflow, and use JPG when you need broad compatibility or a familiar photo format.
