WordPress is an outstanding CMS for creating and managing websites. That includes adding high-quality images along with well-written content. However, you need to incorporate image optimization to ensure the best load speed and performance on the website.
Images are very important for a website; they add a visual appeal and grab people’s attention. But if not optimized, they can slow down loading speed. It affects the user experience as well as the SEO rankings. So, WordPress development services perform image optimization by choosing the suitable file format, resizing the images, compressing their file size, and more.
In this blog, we’ll discuss how to optimize the images for WordPress websites through plugins and manual methods. But first, let’s see what image optimization is.
What is Image Optimization?
Image optimization in WordPress is the process of reducing the images’ file size without sacrificing too much quality. As a part of the WordPress speed optimization services, image optimization can be done by resizing images, compressing them, and choosing the right image format.
For image optimization, compression is needed. Lossy compression is when data that are not necessary is removed; however, quality may be affected. Lossless compression is used to reduce the file size of text files, document files, and other types of files where data integrity is important. Common file formats are JPEG, PNG, and GIF, each with its advantages.
Image dimensions have to be specified. This way, it will look right on different devices, and the browser won’t need to do extra work. Alt text is also essential for accessibility and search engine optimization.
Why is Image Optimization Important for WordPress?
When it comes to optimizing images for WordPress, there are several benefits with respect to the performance, SEO, and user experience of your website. It reduces file sizes, optimizes dimensions, and improves loading speeds. That boosts user satisfaction and search engine rankings, which is why it is one of the WordPress SEO strategies.
- Performance: Images are typically the largest files on a WordPress website, so optimizing them can have a significant impact on page loading speed.
- SEO: Google considers page loading speed to be a ranking factor, so optimized images can help you rank higher in search results. Additionally, Google can extract information from your images and use it to index your pages. By providing descriptive file names and alt text for your images, you can help Google (and other search engines like Bing) understand what your images are about and improve your website’s SEO.
- User experience: Frequent users expect websites to load quickly and display images correctly. If your images are not optimized, your website may load slowly, or images may not display at all. That can lead to a frustrating UX and cause users to leave your website.
When optimizing images for WordPress, choose file formats like JPEG or PNG that balance quality and size. Compress images with Photoshop or online platforms like TinyPNG. WordPress development experts resize images to the correct dimensions for their display. That helps avoid unnecessary data transfer and improves page load times.
Include descriptive alt text in image tags to let search engines know what the image is about. Optimize image filenames with relevant keywords to improve visibility in search results.
So, let’s see the best practices for image optimization on the WordPress website.
Best Practices for Image Optimization
By optimizing your images, you can improve your website’s loading speed, reduce bandwidth usage, improve search ranking, and provide a better UX. That will help attract more visitors and keep them due to faster site speed and navigation.
Resize images before uploading them to WordPress
When you take a photo with your phone or camera, it is typically much larger than the size you need to display on your website. Resizing your images before uploading them to WordPress will reduce the file size and make them load faster.
To resize your images, you can use photo editing software like Adobe Photoshop or an online service like TinyPNG. When resizing your images, be sure to choose the appropriate dimensions for your website.
For example, if your website layout has a maximum image width of 600px, you should resize your images to a width of 600px or less.
Choose the Suitable Format Depending on the Photo or Graphic
There are two main image formats used on the web: JPEG and PNG. JPEG is a good format for compressing photos, while PNG is suitable for images with text or transparent backgrounds.
Here is a general guideline for choosing the right image format:
- JPEG: Use JPEG for photos and other images with complex color variations.
- PNG: Use PNG for images with text, transparent backgrounds, or simple colors.
You can consult with a WordPress development company to understand which file format would be suitable for the images on your website.
Compress Images with Adobe Photoshop or an Online Service
Image compression is the process of reducing the image file size without sacrificing too much quality. There are a number of different image compression techniques, but most image editing software and online services use a lossless compression technique. Lossless compression reduces the file size without removing any data from the image, so there is no loss of quality.
To compress your images, you can use photo editing software like Adobe Photoshop or GIMP or an online service like TinyPNG or Smush. When compressing your images, be sure to choose a compression level that maintains the desired quality.
Enable Caching Plugins
Caching plugins store static versions of your website’s files, including images. This can improve retrieval speed and reduce server load.
To enable caching plugins, simply install and activate a caching plugin like WP Super Cache or W3 Total Cache. Once the plugin is activated, you will need to configure it to store static versions of your website’s images.
Use Lazy-loading Techniques
Lazy loading is a technique that defers the loading of images until they are visible to the user. This can prevent unnecessary requests and quicken page loading.
To use lazy loading, you can install and activate a lazy loading plugin like WP Smush Pro or a3 Lazy Load. Once the plugin is activated, it will automatically defer the loading of your website’s images.
By following these best practices, you can optimize your WordPress images and improve the performance, SEO, and user experience of your website.
Here’s another Pro Tip. Audit your WordPress media library regularly to remove unused images. This keeps your website’s database tidy and saves storage space.
