How to Convert Images to WebP (Smaller, Faster Pages)
If your website feels slow, oversized images are usually the culprit — and WebP is the easiest fix. It typically produces files 25–35% smaller than JPG at the same quality, which means faster loads and better Core Web Vitals. Here's what WebP is and how to convert your images to it.
Convert an image to WebP
Use the Image Converter:
- Open Image Converter and add your JPG or PNG.
- Choose WebP as the output format.
- Download the converted image — everything happens in your browser.
What is WebP, and why use it?
- Smaller files. WebP compresses more efficiently than JPG or PNG, so pages download faster.
- Best of both worlds. It supports both lossy compression (like JPG) and transparency (like PNG).
- Great for SEO. Faster pages improve Core Web Vitals, a Google ranking signal.
- Widely supported. Every modern browser displays WebP.
When to stick with JPG or PNG
- Email attachments and print — JPG is still the most universally accepted format.
- Uploads to older systems that may not accept WebP.
Squeeze out even more
Before converting, resize images to the dimensions you actually display, and use Compress Imageto fine-tune quality. Together with WebP, that's the fastest possible image. See all our image tools.
