Frequently Asked Questions
What's the best image format for SEO in 2026?
WebP is currently the best format for SEO, offering 25-35% smaller file sizes than JPEG/PNG with excellent quality. It has 96% browser support and is recommended by Google for web performance.
How much can image conversion improve website speed?
Proper image conversion and optimization can improve page load times by 25-50%, reduce bounce rates by up to 32%, and significantly improve Core Web Vitals scores for better Google rankings.
Should I convert all my images to WebP?
