The Complete Guide to Web Image Optimization: PNG vs. JPG vs. WebP

Images make up the vast majority of web page weight. If your website has heavy, uncompressed images, your loading times will suffer. Slow pages lead to poor user experience, reduced SEO ranking, and lower e-commerce sales.

Understanding file formats and utilizing proper compression is key to building a fast web storefront.

PNG vs. JPG vs. WebP: Which Should You Use?

Each image format has specific strengths and weaknesses:

• PNG (Portable Network Graphics): Supports transparent backgrounds. Great for logos, icons, and product cutouts, but files can be quite large.
• JPG/JPEG: Ideal for photographs and complex landscapes. It supports high compression levels but does not support transparency.
• WebP: A modern format created by Google that offers superior compression for both photographs and transparent graphics.
