01Resize Images

  • Start by resizing images to the dimensions required by your web portal.
  • Use image editing tools or libraries to resize images while maintaining aspect ratio.
  • Avoid using CSS or HTML to resize images as it can still load the full-size image, leading to slower page loading.
  • Choose appropriate image dimensions based on where the image will be displayed.

02Compress Images

  • Compressing images is a crucial step in image optimization.
  • Use image compression tools or libraries to reduce the file size while maintaining image quality.
  • Balancing between image quality and file size is important to ensure fast loading speed.
  • Consider using modern image formats like WebP or JPEG 2000 that offer higher compression efficiency.

03Lazy Loading

  • Implement lazy loading for images to improve page loading speed.
  • Lazy loading defers the loading of non-visible images until the user scrolls to them.
  • This technique helps reduce initial page load time and bandwidth consumption.
  • Use JavaScript libraries or frameworks that provide lazy loading functionality.

04Use CDN

  • Leverage the power of Content Delivery Networks (CDNs) to optimize image delivery.
  • CDNs distribute images across multiple servers located worldwide, reducing latency and improving loading speed.
  • Choose a reliable CDN provider that offers high-performance image caching and delivery.
  • Configure your web portal to serve images through the CDN.

05Optimize Image Formats

  • Select the most appropriate image format for each image based on its characteristics.
  • JPEG format is ideal for photographs or complex images with many colors.
  • PNG format is best for images with transparent backgrounds or simple graphics.
  • SVG format is recommended for logos, icons, or scalable graphics.
  • Avoid using BMP or TIFF formats as they result in larger file sizes.
