Previous Question Next Question

Optimizing images for faster loading on mobile devices involves reducing file sizes and ensuring efficient delivery without sacrificing quality. This can be achieved through techniques like compression, responsive images, and modern formats.

Example Concept: Use responsive images with the "srcset" attribute to serve different image sizes based on the device's screen size and resolution. Additionally, convert images to modern formats like WebP, which offer better compression and quality than traditional formats like JPEG and PNG.

Additional Comment:

Implement lazy loading to defer off-screen images until they are needed.
Use image CDNs to deliver images from the nearest server location to the user.
Compress images using tools like ImageOptim or online services before uploading them to your site.
Ensure that images have appropriate dimensions to prevent layout shifts, which can affect CLS.
