Images are a huge part of the web—but they’re also one of the biggest culprits behind slow page load times. That’s where WebP comes in: a next-generation image format developed by Google that offers impressive compression without sacrificing visual quality.

Whether you’re a developer, designer, or content creator, understanding how WebP works—and when to use it—can help you deliver faster, more optimized websites. In this post, we’ll break down WebP in plain English and show you how it fits into your image optimization workflow, especially alongside our Image Resizer Tool.

What Is WebP?

WebP is an image format developed by Google that provides superior compression compared to older formats like JPEG and PNG. It supports both lossy and lossless compression, transparency (like PNG), and even animation (like GIF).

✅ Key Benefits of WebP:

• Up to 25-34% smaller than comparable JPEGs

• Maintains high visual quality

• Supports transparency (alpha channel)

• Reduces load times = better SEO and user experience

When Should You Use WebP?

• On websites where performance is a priority

• When optimizing images for Google PageSpeed Insights

• In eCommerce or blog images where size and quality both matter

• As a replacement for JPEGs and PNGs (with browser fallback)

⚠️ Browser Support: WebP is supported by all major modern browsers (Chrome, Firefox, Edge, Safari), but older browsers may still need fallback formats.

How WebP Compares to JPEG and PNG

How to Convert to WebP

If you’re using our Image Resizer Tool to optimize your JPEG and PNG images, you’re already on the right track. While the tool currently supports those two formats, here’s how to integrate WebP into your workflow:

1. Resize your JPEG or PNG with our tool first—get the dimensions right.

2. Then use a WebP converter (like Squoosh, cwebp, or your CDN) to generate the WebP version.

3. Add both the original and WebP versions in your HTML with the <picture> element for fallback:

WebP in a Performance Workflow

1. Resize to proper dimensions using our Image Resizer Tool

2. Strip metadata and compress with WebP

3. Serve via CDN or lazy load

4. Use <picture> for fallbacks

5. Monitor PageSpeed performance gains

Final Thoughts: Should You Use WebP?

Absolutely. WebP is a future-forward format that gives you better performance and smaller file sizes across the board. Paired with traditional JPEG/PNG resizing (especially when you need browser fallback or editing tools), you can create a hybrid image strategy that balances compatibility and performance.

✅ Start by using our Image Resizer Tool to resize and optimize JPEG and PNG images.
Then take it a step further with WebP conversions for a cutting-edge experience.
