WebP format provides 25-35% smaller file sizes compared to PNG while maintaining the same visual quality. This results in faster website loading times, reduced bandwidth usage, and improved user experience. WebP is Google's recommended format for modern web applications.

Yes! WebP fully supports transparency and alpha channels, maintaining all transparent areas from PNG images. This makes WebP perfect for logos, icons, and graphics requiring transparent backgrounds while providing superior compression compared to PNG.

For web use, 80-90% quality provides excellent results with optimal file size reduction. For lossless conversion similar to PNG, use 100%. For maximum compression with acceptable quality, use 70-80%. The default 85% offers the best balance of quality and file size for most images.

WebP is supported by Chrome, Firefox, Safari, Edge, and Opera - covering over 95% of users. For older browser compatibility, consider providing PNG fallbacks or using responsive images with multiple format options in your HTML.

WebP typically reduces PNG file sizes by 25-35% for lossless compression and up to 80% with lossy compression at high quality settings. The exact reduction depends on image complexity - graphics with solid colors achieve higher compression ratios than complex photographs.

WebP support in email clients is limited. Gmail and some modern email clients support WebP, but many others don't. For email newsletters, stick with PNG or JPG formats, or use conditional HTML to serve WebP only to supporting clients with PNG fallbacks.

The converter handles PNG files up to 10MB efficiently, supporting high-resolution images and complex graphics. Larger files will be processed but may take longer depending on image dimensions and complexity. WebP conversion maintains image quality while significantly reducing file size.
