It helps websites load faster and improves user experience.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What is Image Optimization<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Image optimization is the process of making images lighter so that web pages can load quickly. Large image files can slow down a website.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Why Image Optimization is Important<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Optimized images improve website speed and performance. Faster websites provide a better experience for users and also help in SEO rankings.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Choosing the Right Image Format<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Different image formats are used for different purposes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">JPEG is used for photos because it has good quality with smaller file size.<br>PNG is used for images that need transparency.<br>WebP is a modern format that gives high quality with very small file size.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Reducing Image Size<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You should always resize images before uploading them to a website. Do not use very large images if a smaller size is enough for display.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Using Proper Dimensions<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Always use images with the correct width and height according to your layout. This prevents unnecessary loading of large images.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Alt Attribute Usage<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The alt attribute should always be added. It improves accessibility and helps search engines understand the image.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Lazy Loading<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Lazy loading means images load only when they are needed on the screen. This improves page speed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Example of Lazy Loading<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">&lt;img src=&#8221;image.jpg&#8221; alt=&#8221;Sample Image&#8221; loading=&#8221;lazy&#8221;&gt;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Summary<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Image optimization makes websites faster and more efficient. By using proper formats, reducing size, and applying techniques like lazy loading, you can improve performance and SEO.<\/p>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1777296885042\"><strong class=\"schema-faq-question\"><\/strong> <p class=\"schema-faq-answer\"><\/p> <\/div> <\/div>\n\n\n<div class=\"yoast-breadcrumbs\"><span><span><a href=\"https:\/\/gigz.pk\/html\/\">Home<\/a><\/span> \u00bb <span class=\"breadcrumb_last\" aria-current=\"page\">HTML Fundamentals (Beginner) > Images &#038; Media > Image Optimization Basics<\/span><\/span><\/div>","protected":false},"menu_order":23,"template":"","class_list":["post-102","lesson","type-lesson","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Image Optimization Basics - HTML learning mastery<\/title>\n<meta name=\"description\" content=\"Learn image optimization in HTML.
