Why Convert PNG to WebP?
WebP was developed by Google specifically for the web. It supports both lossy and lossless compression, transparency (alpha channel), and even animation. For websites, WebP images load faster because they're significantly smaller than equivalent PNGs. Google PageSpeed Insights and Core Web Vitals specifically recommend serving images in WebP format.
WebP Browser Support
WebP is now supported by all major browsers including Chrome, Firefox, Safari, Edge, and Opera. As of 2024, over 97% of web users have a browser that supports WebP. The only exceptions are very old browser versions. For maximum compatibility, many websites serve WebP with a PNG or JPG fallback using the HTML picture element.
WebP Quality Settings
Use the quality slider to control the compression level. For lossless conversion (identical to PNG), set quality to 100%. For web use, 80-90% quality produces visually identical results with much smaller file sizes. For thumbnails and previews, 70-80% is often sufficient. The converter shows you the file size reduction for each image so you can find the right balance.
