WebP vs JPG: Which Image Format is Better?
WebP and JPG are the two most popular formats for web images. JPG has been the standard since the 1990s, while WebP was developed by Google in 2010 as a modern replacement. Both use lossy compression for photographs, but they differ significantly in file size efficiency, feature support, and compatibility. This comparison helps you decide which format to use for your specific needs.

When to Use WebP
Use WebP when you control the delivery platform (your own website) and want the smallest possible file sizes. WebP is the best choice for web performance optimization, especially for hero images, product photos, and any image-heavy pages. It is also the right choice when you need both compression and transparency in a single format.
When to Use JPG
Use JPG when you need maximum compatibility across all platforms, email clients, and software. JPG is the safest choice for email attachments, social media uploads (platforms will re-encode anyway), and any situation where you cannot guarantee WebP support. JPG is also preferred for print workflows and professional photography distribution.
