Image optimization is essential for any website or blog. Not only do images make your content more visually appealing, but they also help to improve your site’s load time and overall performance. Unfortunately, many people still don’t know how to properly optimize their images, which can lead to subpar results. To help you get the most out of your images, we’ve put together a list of 10 must-know image optimization tips. From choosing the right file format to compressing your images, these tips will help you ensure that your images are working hard for you—not against you.

Resize and Crop Your Images

• Resizing and cropping your images is one of the most important image optimization techniques. By resizing your images, you can ensure that they are the correct size for their intended use. This can help to improve load times, as well as save you storage space.
• Crop your images to remove any unnecessary or unwanted elements. This can help to focus attention on the main subject of the image, and can also help to improve load times.

Use the Right File Format

• There are a lot of different image file formats out there, and each has its own advantages and disadvantages. The two most popular formats for web images are JPG and PNG.
• JPG is also good for images that need to be compressed to save space. However, JPG files can't be transparent, so they're not ideal for graphics or logos.
• PNG is best for graphics and images with transparency. It's also good for images that don't need to be compressed. However, PNG files are generally larger than JPG files, so they can slow down your website if you're not careful.

Optimize Image Filenames

• When it comes to image optimization, one of the most important things you can do is to make sure that your image filenames are as descriptive and keyword-rich as possible.
• Not only will this help your images rank better in search engines, but it will also help people understand what your images are about when they see them in search results.
• To optimize your image filenames, start by including keywords that describe the subject of the image. For example, if you have an image of a dog, include keywords like 'dog,' 'puppy,' or 'canine.'

Compress Your Images

• Compressing your images is the best thing. Not only do they have the power to engage visitors and drive conversions, but they also play a major role in how your site ranks in search engine results pages.
• That's why it's so important to optimize your images for both SEO and performance. By compressing your images, you can reduce their file size without sacrificing quality, making them faster to load and easier for search engines to index.

Use a Content Delivery Network (CDN)

• Content delivery networks can speed up the delivery of content by caching it at multiple locations around the world and delivering it from the location that is closest to the user. This can reduce latency and improve performance for users who are located far away from the origin server.

Optimize Alt Text and Title Text

When it comes to optimizing images for the web, there are two key elements you need to focus on: alt text and title text. Both of these text elements play an important role in helping search engines understand what your images are all about, so it's essential that you take the time to optimize them properly.

Here are some tips for optimizing your alt and title text:

1. Make sure your alt text is descriptive and keyword-rich.

2. Use different keywords for different images.

3. Keep your title text short and to the point.

4. Use keywords in your title text that are relevant to the image.

By following these tips, you can help ensure that your images are properly optimized for the web. This will help improve your website's overall SEO and visibility in the search engines.

Use CSS Sprites

If you have a lot of small images on your website, you can combine them into one larger image called a sprite. Then you can use CSS to position the different images on the page. This reduces the number of HTTP requests, which can speed up your page loading time.

Make Sure Your Site is Mobile-Friendly

• In today’s world, it’s absolutely essential that your website is mobile-friendly. More and more people are using their smartphones and tablets to browse the internet, and if your site isn’t optimized for smaller screens, you’re going to lose a lot of potential visitors.
• There are a few different ways to make sure your site is mobile-friendly. First, you can use responsive design, which means that your site will automatically adjust to fit any screen size. 

Use images sparingly

• Images are an important part of any website, but they can also be one of the biggest sources of loading problems. If you’re using too many images, or large images that aren’t properly compressed, your pages will take forever to load—and nobody wants to wait around for a slow website.
• To avoid this problem, only use images when they’re absolutely necessary, and make sure to optimize them for the web. 

Implement Lazy Loading

• Lazy loading is a technique for loading resources on demand. It's particularly well-suited for images, since images are often the slowest to load resources on a web page. By deferring the loading of images until they're needed, lazy loading can significantly improve the performance of a web page.
• There are several ways to implement lazy loading, but the most common is to use the JavaScript library jQuery. In order to use jQuery for lazy loading, you'll need to add the following code to your web page:

$(function() {

$('img').lazyload();

});

Lazy loading is an easy way to improve the performance of your web pages, especially if you have many images or other slow-loading resources. If you're not using jQuery already, it's a good idea to start using it for this purpose.
