One of the best ways to improve your images is to convert your regular JPG files to the new, quicker, and efficient WebP image format. In this article, we’ll cover all that you need to know when converting JPG to WebP including the how and why, WebP use cases and tools, as well as the technical considerations and SEO advantages.
What is WebP?
WebP is a Google-developed, advanced image format that can be lossy or lossless. WebP images take up much less space compared to the older JPG or PNG formats, without noticeable loss in image quality. It also supports transparency, as PNG does, and animation, as GIF does, so is a good all around solution for today’s web and apps.
Why Convert JPG to WebP?
Here are some great arguments for changing your JPG images to WebP:
- Smaller File Size: WebP images are as much as 34% smaller than JPGs images without any loss of image quality.
- Quicker Loading: Smaller images load quicker which is a better user experience and reduces bounce rates.
- Better SEO: Google likes fast-loading pages and properly optimizing images is one important part of the mix that affects your site’s Core Web Vitals.
- Lower Bandwidth Consumption: This is especially relevant for mobile users, and also for sites with heavy traffic.
- Browser Compatibility: WebP is supported by Chrome, Firefox, Edge, and Opera.
Best Use Cases for WebP
WebP is ideal for:
- E-commerce product photos
- Blog post images
- Portfolio galleries
- Mobile-friendly websites
- Progressive web apps (PWAs)
- Social media sharing previews
How to Convert JPG to WebP Easily
Converting your images doesn’t require complex software or expensive tools. Here are the most accessible methods:
1. Online Conversion Tools
Several free online platforms allow quick conversion without downloading software. These tools typically offer:

These apps offer more control over image quality, metadata, resizing, and naming conventions.
3. Command-Line Tools
Advanced users and developers might prefer command-line tools for automation:

Considerations Before Conversion
WebP is great for the web, but note the following:
- Browser Support: WebP is supported by most modern browsers, but it might not work with older ones, like Safari. Adopt fallback strategies if necessary.
- Back Up Original Files: Always retain a copy of the original JPG prior to converting in case you need to re-edit or convert at some point in the future.
- See visual check: lossy webP artifacts can occur. Always double-check the quality of converted images.
How to Use WebP Images on Websites
Integrating WebP into your website can be done in several ways:
Using the <picture> tag:
<picture>
<source srcset="image.webp" type="image/webp">
<img src="image.jpg" alt="Example Image">
</picture>This ensures WebP is served when supported, and JPG is used as a fallback.
Using CMS plugins: For WordPress users, plugins such as ShortPixel, EWWW Image Optimizer, and WebP Express do the work of automatically converting images to WebP format and serving WebP images throughout the site.
CDN Support: CDNs such as Cloudflare and BunnyCDN can automatically convert images to WebP when the browser supports it.
Performance Gains from JPG to WebP Conversion
Switching from JPG to WebP can dramatically improve site metrics:
- Smaller Page Size: Smaller files download faster.
- Better page speed scores: WebP can directly enhance the score on platforms such as Google PageSpeed Insights or GTmetrix.
- Optimized for Mobile: Less bandwidth usage is especially beneficial for users on mobile, who may be limited in their data.
