Pre-optimize Source Images Before Import
Next.js can optimize images at build time, but starting with a 10 MB photo wastes processing power. Compress and resize before adding to the project.
Use Width And Height To Prevent CLS
The Next.js Image component needs explicit width and height to reserve space. Always provide these even for responsive images.
Choose The Right Loading Strategy
Use priority loading for hero images and lazy loading for below-the-fold content to balance performance and perceived speed.
