bookImage Optimization

Choosing the right image format is a key part of optimizing images for web performance. Formats like JPEG, PNG, and SVG each have their strengths.

  • JPEG is ideal for photographs and complex images with many colors, as it offers good compression and small file sizes;
  • PNG is better for images that require transparency or have sharp edges, such as logos and icons, but usually results in larger files;
  • SVG is a vector format, perfect for simple graphics, icons, and illustrations that need to scale without losing quality.

Compressing files further reduces their size, which improves page load times. Optimized images not only speed up your website but also enhance user experience and search engine optimization (SEO).

Always test your images on multiple devices to ensure they look good everywhere. Use the smallest file size that still maintains acceptable visual quality. This reduces bandwidth usage and helps your pages load faster, especially on mobile devices or slower connections.
