Are you looking to optimize images on your WordPress website? If yes, then you landed in the right place!
Images are one of the most important elements on a page, but they also contribute to page weight. If you want your website to be well-optimized and fast, then you need to optimize your images.
Optimizing images not only makes your website fast but also helps you in boosting user experience and SEO. This guide will walk you through different techniques and plugins that you can use to optimize your WordPress images.
Let’s get started!
What is Image Optimization?
Image optimization is the process of reducing the file size of an image without compromising its quality. This is important for two reasons: first, to reduce the amount of bandwidth that is used when loading the image, and second, to improve the load time of the page.
And there are a number of ways to optimize an image, including reducing its dimensions, compressing its file size, and using a content delivery network (CDN).
In other words, optimizing images is a balancing act of reducing image file size without sacrificing quality. This way, you can have beautiful images on your website without slowing down your page speeds.
Importance of Optimizing Images
Optimizing images is very important if you want to improve your blog’s performance, mainly because images are the heaviest files on your website.
Here is why optimizing images are essential:
- Optimizing images make your website load faster.
- By compressing and optimizing images, you can boost user experience.
- Search engines like Google give priority to websites that load fast. Hence, you can improve your site’s SEO if you have optimized images.
- This practice also saves a lot of your space in your web hosting.
Methods to Optimize Images for WordPress
There are many methods to optimize images in WordPress. Here are the top ways to make your images optimized:
1. Compress WordPress Images
One of the excellent ways to optimize images is to compress your images. There are a few different ways to compress images, but one of the easiest is to use a WordPress plugin like Smush. It will automatically compress your images as you upload them to your website.
Another way to compress images is by using online editing tools like TinyPNG. TinyPNG is a free online tool that lets you compress images without losing quality. It supports JPEG, PNG, and also WebP image formats.
Whichever method you choose, compressing your images can help speed up your website and improve your overall website performance.
2. Resizing Images
Another excellent method to optimize images is to resize your WordPress images. By default, WordPress creates four different sizes of all your website images as follows:
- Thumbnail: 150x150px
- Medium: 300x300px
- Large: 1024x1024px
- Full Size: original uploaded image size
You can also change these default image sizes as per your needs from WordPress media. Simply go to Settings > Media and set your preferred image size as shown in the image below.
You can also use an online tool to resize images. There are several tools available, and they’re typically straightforward to use. Simply upload the image you want to resize, select the new dimensions, and download the resized image.
3. Using CDN
A content delivery network (CDN) can significantly improve the performance of your website by serving images from a server that is closer to the user’s location. This reduces the latency and improves the speed of image loading.
There are many different CDN providers to choose from, and each has its own advantages and pricing structure. To get started, you can simply choose a provider and then configure your website to serve images from their CDN.
Once your website is configured to use a CDN, all of your images will be automatically served from the CDN’s servers. This can significantly improve the performance of your website, especially if you have users from all over the world.
4. Clean WordPress Media Library
Another great way to optimize images is to clean your WordPress media library. The WordPress media library is a great way to keep all your images and other media files organized. However, over time it can become cluttered and messy, so I recommend cleaning your media library.
You can delete unused images from the media library because having too many unused images can slow down your overall website. Also, these images take up a lot of space in your hosting.
The first method is to clean the media library manually. Here is how to do it:
Open WordPress and navigate to Media > Library. Now, you can see all your images and other documents.
Next, you can select and delete images one by one or can also use the ‘bulk select’ option to delete images in bulk, as shown in the image below.
The second method is to use a media cleaner WordPress plugin. I recommend using the Media Cleaner plugin. Simply install and activate this plugin and navigate to Media > Cleaner, as shown in the image below.
Now, click on the Scan button to scan all unused images in the media library automatically. After the scan completes, you will find all the unused images under the Issues section, as shown in the below image.
The final step is to select images that you wish to delete and select Delete.
5. Use GTmetrix to Find Unoptimized Images
GTmetrix is an excellent website performance testing tool that shows your site’s overall performance score and provides various optimization opportunities. One of these opportunities is image optimization.
To use this tool, enter your website URL in the given field and select ‘Test your site’. After a few minutes, you will see a detailed performance report of your site. Here, you will get various suggestions to boost the site’s performance.
6. Defer Offscreen Images
When loading a web page, deferring offscreen images can help improve performance. By deferring offscreen images, the browser can continue to load other resources while the images are being downloaded.
This can help improve the overall loading time of a web page. In addition, deferring offscreen images can also help reduce data usage.
7. Use Next-Gen Image Formats
As discussed earlier, images are an important part of any website or blog. They can help to break up the text, add visual interest, and illustrate a point. However, images can also be a major source of file size bloat, especially if they are not optimized.
There are a number of ways to optimize images, but one of the best is to use next-gen image formats. These formats, like WebP and JPEG-XR, offer better compression than traditional JPEGs and PNGs, meaning that your images will take up less space without sacrificing quality.
