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.
