Why convert JPG to WebP for websites?
Page speed is a direct Google ranking factor, and images are typically the largest contributor to page weight. Converting JPG images to WebP reduces file size by 25–35% at equivalent visual quality — meaning your pages load faster, use less bandwidth, and score better on Google PageSpeed Insights and Core Web Vitals. If you're a web developer or running a website on WordPress, Shopify, or any other platform, switching to WebP for your images is one of the highest-impact optimisations you can make for both user experience and SEO.
How much smaller will my WebP file be?
On average, WebP files are 25–35% smaller than JPG at the same visual quality. The exact saving depends on the image content — photos with lots of detail and colour variation tend to see the largest savings, while simple graphics may see less. FreeImageConverter shows you the before and after file size for every conversion so you can see exactly how much space you've saved. Use the quality slider to find the sweet spot between file size and quality for your specific use case.
