How Images Effect Core Web Vitals (LCP)
Google uses a metric called LCP (Largest Contentful Paint) to measure how fast your page feels. Large images delay LCP, which directly lowers your SEO ranking. To score 100 on PageSpeed Insights:
- Resize Dimensions: Never display a 500px image using a 3000px source file. Resize it to the exact display size.
- Use WebP Format: Select 'WebP' in our tool. It creates files 30% smaller than JPG with the same quality.
- Compress: Use a quality setting of 80%. This is the sweet spot for the web—indistinguishable from original but drastically lighter.

Website Image Optimization FAQs
What is the standard size for a website hero image?
The most common resolution for full-width hero banners is 1920 x 1080 pixels (Full HD). This ensures the image looks crisp on desktops while maintaining a reasonable file size.
Should I use JPG, PNG, or WebP for my website?
WebP is vastly superior for modern websites, offering 30% smaller file sizes than JPG with identical quality. Use JPG as a fallback for photographs. Only use PNG for logos or icons requiring transparency.
How do images affect my site's SEO?
Google weighs "Page Experience" heavily. Large images slow down your page (specifically LCP - Largest Contentful Paint), which directly hurts your rankings. Optimized images lead to faster loading, lower bounce rates, and better SEO.
What is the ideal file size for a web image?
Aim for under 200KB for large banner images and under 70KB for smaller blog or product images.
