WebP is Google's modern image format built for the web. It delivers the same visual quality as JPG at 25–35% smaller file sizes — which means faster page loads, lower bandwidth costs, and better Core Web Vitals scores. Converting your JPG images to WebP is one of the fastest wins for website performance.

Why Convert JPG to WebP?

Google developed WebP specifically for web use. It supports both lossy compression (like JPG) and lossless compression (like PNG), plus transparency (unlike JPG).

Key reasons to convert JPG to WebP:

JPG vs WebP — Size and Quality Comparison

JPG WebP (lossy)
Compression type Lossy Lossy or lossless
Typical file size 100 KB 65–75 KB
Quality Good Same or better
Transparency No Yes
Browser support Universal All modern browsers
Best for Photos, web Web, photos, graphics

A typical product photo that's 200 KB as a JPG becomes ~130 KB as WebP at the same visual quality. Multiply that across a website with hundreds of images and the impact is huge.

How to Use WebP Images on Your Website

</picture>

In WordPress:

Use a plugin like Smush or ShortPixel to automatically serve WebP to supported browsers.

In CSS backgrounds:

Use the <picture> polyfill or serve WebP conditionally based on browser Accept headers.

Does WebP Work on All Browsers?

WebP is supported by Chrome, Firefox, Safari (14+), Edge, and Opera — covering over 95% of web users. The <picture> element with a JPG fallback covers the remaining 5%.
