About this tool
WebP is Google's modern image format that provides significantly better compression than PNG and JPEG while maintaining comparable visual quality. Converting your PNG images to WebP can reduce file sizes by 25-35% for lossless compression and even more with lossy settings, which directly translates to faster page load times and lower bandwidth costs.
This tool handles the conversion entirely in your browser using the Canvas API. Upload a PNG (or JPEG), adjust the quality slider to find the right balance between file size and visual quality, and download the WebP result. No server-side processing, no upload queues, no watermarks.
WebP is supported by all modern browsers - Chrome, Firefox, Safari, Edge - making it a safe choice for web images in 2024 and beyond. If you are building a website or optimizing images for a web application, switching from PNG to WebP is one of the easiest performance wins available.
The quality slider lets you control the compression level. At 80-90%, most images are visually indistinguishable from the original PNG while being significantly smaller. For screenshots and graphics with text, you can often go as low as 70% without noticeable quality loss.
