Understanding Image Formats: PNG vs JPG vs WebP

Choosing the right image format is essential for balancing quality, file size, and compatibility in your projects. PNG, JPG, and WebP are among the most popular formats, each with unique strengths and weaknesses. This guide compares them to help you make informed decisions.

What Are PNG, JPG, and WebP?

PNG (Portable Network Graphics)

PNG is a lossless image format that supports transparency and high-quality graphics. It’s widely used for logos, icons, and images requiring sharp details or transparent backgrounds.

JPG (Joint Photographic Experts Group)

JPG is a lossy image format optimized for photographs and complex images. It achieves smaller file sizes by sacrificing some quality, making it ideal for web use.

WebP

WebP is a modern format developed by Google, offering both lossy and lossless compression. It supports transparency and animations, providing superior compression compared to PNG and JPG.
