Convert any JPG or JPEG file to WebP online for free. Upload your image and download a smaller WebP instantly. No signup, no software, no watermarks. Works in any browser on Mac, Windows, iPhone and Android.
WebP is the modern image format developed by Google and supported by all major browsers. At the same visual quality setting, WebP typically produces files 25 to 35 percent smaller than JPG. Switching your website or app images from JPG to WebP reduces page load times, lowers bandwidth costs and improves Core Web Vitals scores.
Use the quality slider to control the output size. A setting of 80 to 85 for WebP produces results comparable to JPG at 90 to 95, with a smaller file. Adjust and preview before downloading to find the right balance for your use case.
WebP is now the default choice for web images. Here is who benefits most from converting existing JPGs.
Replacing JPG images with WebP on a website typically reduces the total image payload by 25 to 35 percent without any visible quality change. Lighter pages score better on Google PageSpeed Insights, pass Core Web Vitals thresholds more easily, and keep visitors from leaving before the page finishes loading. WebP is supported by Chrome, Firefox, Safari 14+, and Edge — covering virtually all web traffic.
Product pages with many high-resolution images are some of the heaviest pages on the web. Converting product photography from JPG to WebP reduces the image payload of a product page significantly, improving load times particularly on mobile where slower connections make image size a direct conversion factor. Faster product pages consistently show higher add-to-cart rates.
WordPress, Webflow, Squarespace and most modern CMS platforms accept WebP uploads. Converting your article images and featured photos to WebP before uploading gives you faster pages without changing anything about how you publish content. Many hosting plans also charge by bandwidth — smaller images directly reduce those costs.
Quick answers about how this tool works and how to get the best results.
Yes, as of 2021 all major browsers support WebP — Chrome, Firefox, Safari (14+), Edge and Opera. WebP covers over 97% of global browser traffic. If you need to support very old browsers (Internet Explorer, Safari 13 and earlier), you would need to serve a JPG fallback alongside the WebP using a picture element, but this is no longer necessary for the vast majority of web users.
For photographic images, WebP at quality 80 typically produces files 25 to 35 percent smaller than JPG at quality 85. The exact saving depends on the image content — highly detailed photographs see the biggest gains, while flat illustrations or graphics with large areas of solid colour see smaller differences.
Yes, WebP supports full alpha transparency — something JPG cannot do. If your original JPG has no transparency, the WebP output will also have none. If you want to add a transparent background after converting, use the Remove Background tool on PictTools.
Yes. The conversion runs in your browser. Your JPG is never sent to a server, and nothing is stored or transmitted. Closing or reloading the tab clears the image data from memory.
