What Is WebP and Why Convert Your Images to It?
WebP is a modern image format developed by Google that provides both lossy and lossless compression for images on the web. Compared to older formats like JPG and PNG, WebP files are typically 25–35% smaller at a similar level of visual quality. Smaller images mean faster page load times, lower bandwidth usage, and a better experience for your website visitors — all of which are factors search engines like Google consider when ranking pages.
This free online tool lets you convert JPG, JPEG and PNG images to WebP in seconds, entirely inside your web browser. There’s no need to install software, create an account, or upload your files to a remote server — and because everything runs on your own device, there’s no limit on how many images you can convert. Use it once or a thousand times, it will always be free.
Why Website Owners Convert to WebP
- Improved page speed: Smaller images load faster, which directly improves Core Web Vitals like Largest Contentful Paint (LCP).
- Better SEO rankings: Google uses page experience signals, including load speed, as part of its ranking criteria.
- Lower bandwidth costs: Smaller files reduce hosting and CDN bandwidth usage.
- Same visual quality: WebP retains sharp, high-quality images even at reduced file sizes.
