How to Reduce Image Size for Websites
Why page speed matters
Large images are the #1 cause of slow pages. Google uses Core Web Vitals — optimizing images improves SEO and conversions.
Best formats
Photos: WebP or JPG. Graphics with transparency: WebP or PNG. Use PNG to WebP or JPG to WebP converters.
Workflow
1. Resize to display size (max 1920px width). 2. Compress or convert to WebP. 3. Lazy-load on your site.
