Why convert JPG and PNG to WebP?
WebP is a modern image format that provides better compression than JPG and PNG, often resulting in 20–70% smaller file sizes with similar visual quality. That's why it's widely used for faster websites, landing pages, and blogs.
TinyRaster's JPG & PNG to WebP converter runs entirely in your browser using HTML5 canvas. Your files are never uploaded to any server — all processing happens locally on your device. Just drop an image, adjust the WebP quality slider if needed, and download the optimized result.
Use this tool when you need a quick JPG to WebP converter online or a simple PNG to WebP converter for images you plan to use on websites, apps, or emails. If you work only with PNG files and want a focused page, you can try the dedicated PNG to WebP converter. After converting, you can also compress images or resize images to fine-tune performance and layout before publishing.
