Why Convert to WebP?
Smaller File Sizes
WebP produces 25-80% smaller files compared to PNG and JPEG at the same visual quality. This means your website loads faster, uses less bandwidth, and provides a better experience for visitors on slow connections.
Better SEO & Performance
Google recommends WebP as part of Core Web Vitals optimization. Using WebP images can improve your PageSpeed Insights score, boost your SEO ranking, and help you meet the Largest Contentful Paint (LCP) threshold.
Universal Browser Support
WebP is supported by Chrome, Firefox, Edge, Safari 14+, Opera, and all major mobile browsers. Over 97% of web users worldwide can view WebP images without any compatibility issues.
Lossy & Lossless Options
WebP supports both lossy compression (like JPEG, with adjustable quality) and lossless compression (like PNG, with no quality loss). It also supports transparency (alpha channel) for images that need a transparent background.

Tips for Best Results
- Use 80-85% quality for general web images — this provides excellent visual quality with significant file size reduction.
- For product photos and detailed images where quality matters, use 90-95% quality.
- For thumbnails and decorative images, 60-75% quality is usually sufficient and produces very small files.
- PNG images see the biggest savings when converted to WebP — often 50-80% smaller.
- JPG images see moderate savings — typically 25-35% smaller at equivalent visual quality.
- Test different quality levels and compare results side by side before downloading.
- You can re-convert with a different quality setting without re-uploading — just adjust the slider and click Convert again.
- WebP supports transparency, making it a great replacement for PNG images with transparent backgrounds.
