PNG to WebP Converter – Smaller Files, Same Visual Quality

WebP is Google's modern image format, specifically designed to produce smaller files than both PNG and JPEG while maintaining equivalent or better visual quality. Converting your PNG images to WebP is one of the most impactful optimizations you can make for website performance.

Google's own Core Web Vitals guidelines and PageSpeed Insights tool actively recommend serving images in next-generation formats like WebP. Websites that switch from PNG to WebP typically see image size reductions of 25–35% compared to lossless PNG, and even more when using lossy WebP compression. This directly translates to faster page load times, lower bandwidth costs, and improved Google search rankings.

Our PNG to WebP converter supports both lossless and lossy WebP output. Use the quality slider to control the compression level.
