Resizing images⁚ Ensure images are the appropriate size for their intended use on the website. Avoid using oversized images that take longer to load.

Choosing the Right Image Format

The image format can significantly impact file size and loading times. Consider these options⁚

WebP⁚ WebP is a modern image format that offers superior compression compared to JPEG and PNG. It supports transparency and alpha, making it a versatile option.
JPEG⁚ This is a widely supported format for photographs, offering high quality with efficient compression.
PNG⁚ Use PNG for images with transparent backgrounds or sharp lines, where quality is paramount.

Lazy Loading

Implementing lazy loading can significantly enhance user experience, especially for pages with many images. Most popular Content Management Systems (CMS) offer lazy loading plugins or settings;

Content Delivery Networks (CDNs)

CDNs help deliver website content, including images, from servers located closer to users. This reduces latency and improves image loading times, particularly for users in different geographical locations. Popular CDN providers offer cost-effective solutions for image optimization.
