Images may be a great complement to your website’s content, whether they are used to visualize data or to illustrate ideas and concepts. As a result of this, your pages may take longer to load because of the extra weight they carry.

Fortunately, optimizing your pictures and improving the efficiency of your site is as simple as following a few simple steps. Not just will you save a lot of space. However, you’ll also require less bandwidth, resulting in a better User Experience (UX).

What’s image optimization, and how does it assist your website for better results?

We’ll go deep into this.

Afterward, we’ll provide seven strategies for efficiently optimizing photos that you may utilize. These will 100% help you!

What are we waiting for?


When it comes to your site’s performance, image optimization is crucial.

As a result of the picture optimization process, file sizes can be reduced without sacrificing quality, or at least not to the stretch that the ordinary visitor would notice it. Overall page size will be reduced, as well as loading speed.

Then why is this so essential to you?

Short version: A sluggish website is the misery of every business and can raise your abandonment rates. An anxious blog reader or an e-commerce customer on the checkout page are both examples of impatient visitors.

Users’ attention spans are getting shorter. Thus it’s critical that your site loads within a few seconds. If the web page load time grows from 1 second to 3 seconds, the bounce rate grows by 32 percent. It is estimated that 90 percent of visitors will abandon a website if it takes more than 5 seconds to load.

Optimizing your photos can lead to more income and lower expenditures for your organization. By maximizing your hosting provider’s bandwidth, for example, you may avoid spending more than what’s necessary.

Your visitors’ mobile UX may also be improved by increasing the speed at which your pages load. As a result, your Search Engine Optimization (SEO) will improve, as Google ranks your site based on mobile-first crawling.

Indeed, improved pictures can speed up the process of backing up data. Useful for replicating your site or migrating to a new hosting provider. As a sole proprietor, you may use the extra time saved to focus on other important parts of your firm.

What are the best practises for optimising your website’s images? (7 Key Tips)

Maintaining a balance between your site’s visual attractiveness and its performance can be difficult. We’ve compiled a list of seven essential ideas to help you optimize your pictures to make them easier.

1. Which Image File Format Is Best For You?

In order to reduce the file size of your photos, it’s essential that you select a suitable format. Images come in various formats, each with its own benefits and downsides. They could be compressed to save a lot of space, or they can be preserved in their original image quality and data.

Some examples of popular file formats are JPEG, PNG, GIF, and WebP (web page format).

For sophisticated photographs or designs involving people, locations, or things, use a JPEG (Joint Photographic Experts Group), often known as a JPEG. JPEG files may display millions of colors.

Despite its high-quality pictures, the PNG (Portable Network Graphics) format has a tendency to create larger file sizes. Unlike JPEG, this format is better suited to photos with fewer colors. In general, PNGs are a good choice for screenshots of user interfaces (UI), which often change colors fast throughout the capture process.

GIF is another picture format that is often used (Graphics Interchange Format). Memes, whether static or animated, are widely shared on social media. For example, unlike JPEGs and PNG files, which may show millions of colors each, GIFs are limited to 256 colors each. It’s typically not a good idea to convert pictures to GIFs if keeping quality is important. As a practical matter, however, GIF files are generally smaller than JPEGs or PNGs.

WebP is the last picture format we’ll look at. It was developed by Google. As with JPEGs and PNGs, WebP pictures have comparable image quality. WebP compression, on the other hand, has the advantage of using 25–34 percent less space. Most major browsers now accept this file type, making it a good choice if you want to maximize your site’s speed.

2. Compare Your Site’s Current Performance

If you wish to optimize your pictures, you should start by measuring your site’s performance. This might help you determine how much effort will be required to improve the performance of your site and which activities should be prioritized in the process.

You may use free tools such as Google PageSpeed Insights or Pingdom Tools to test your site’s performance. Enter your website’s URL and click the “Test” button to begin. PageSpeed Insights will be used to demonstrate the procedure.

First, you should enter your website’s URL into the input box provided and click Analyze to begin. This will take you directly to the results page without having to do anything else.

Additionally, you’ll be given advice on how to improve your site’s performance. Examples include resizing pictures and delivering them in next-generation formats.

Both mobile and desktop sites may be tested. PageSpeed Insights loads the Mobile tab by default, but you may change this. The Desktop option at the top of this page allows you to switch between desktop and mobile.

If your site’s speed and performance aren’t up to par, the tips given can help. As part of the advice, optimizing images is often included.


3. Before exporting your images, resize them

Resizing your photos before exporting and uploading them to your WordPress site is another technique to optimize your images. If you’re working with raw photographs from a DSLR camera, this approach can be very useful.

It’s ideal for resizing photos to the precise proportions they were intended to be shown. In the case of a banner with a maximum display width of 1200px, it is not required to provide a 3600px picture.

Large picture sizes might increase your site’s loading time, resulting in greater abandonment rates and poor UX, as we’ve already said. GIMP, Photoshop, or Pixlr may be used to resize or scale down your photos.

If you resize and scale photos before saving and exporting them, you may considerably reduce their file size.

4. Automatically optimise images in WordPress with a WordPress plugin

A picture may be optimized reasonably easily, but the procedure must be repeated every time an image is uploaded to your site. Using a WordPress plugin, you may automate picture optimization rather than doing it manually.

Image compression and optimization are made easier using TinyPNG. But there are some more to consider. One is the optimal solution.

It does this by taking consideration of the end-device user’s throughout the optimization phase. A worldwide Content Delivery Network serves all image types. Instead of replacing the original pictures with optimized versions, this plugin creates optimized versions. Changes are instead made on the fly.

EWWW Image Optimizer is another popular WordPress plugin that’s worth checking out.

Use this tool to optimize each picture that appears on your web pages. The software, like Optimole, sends pictures over a CDN and optimizes them for specific devices. It also has a function called lazy loading, which we’ll examine at a moment’s notice.

Imagify is a WordPress plugin that offers different methods of compression.

If you want to compress your photos, Imagify offers three degrees of compression: normal and extreme (also lossy). When you upload pictures and thumbnails to WordPress, this application optimizes them automatically. It also includes a Bulk Optimizer for existing images.

ShortPixel is a final WordPress image optimization plugin that has received a lot of acclaim.

Your pictures are automatically optimized when you use this plugin, just as with the other plugins listed above. In order to compress formats such as JPEG, PNG, GIF, and WebP effectively, ShortPixel employs both lossy and lossless compression. Photographers will also like its use of glossy JPEG compression.


5. File size may be reduced by compressing images.

Lossy or lossless compression can be used to optimize pictures. The benefits and downsides of each compression style are similar to those of the various picture formats.

Images are compressed using lossy compression, which reduces their size but also degrades their quality. There are two lossy formats that we discussed before, namely JPEGs and GIFs. As a result of compression, JPEGs’ quality is generally so modest that the human eye does not detect it.

However, lossless compression decreases picture size without sacrificing quality. This is achieved by removing superfluous metadata from JPEGs and PNG images, respectively. The quality of even lossless formats can degrade, depending on the compression technique employed.

Because of this, you should evaluate your unique demands while selecting a compression method. It’s a good thing that most image optimization programs make intelligent decisions depending on the image’s content, though!

TinyPNG is one of the most used image compressing web tools.

This application allows you to submit an image, and it will automatically compress it so that you can download and utilize the optimal version. TinyPNG is also available as a WordPress plugin.

Your picture will be optimized by TinyPNG once it has been submitted to WordPress. Your current pictures may also be optimized in bulk by heading to Media > Bulk Optimization.

PNGGauntlet is another excellent image compression tool to consider.

To produce tiny PNG files, this method integrates a number of tools and employs lossless compression techniques. JPG, GIF, TIFF, and BMP have supported image formats for conversion to PNG.

Windows users can download the PNGGauntlet program. Alternatives exist for Mac and Linux, like ImageOptim and Trimage.

6. This technique allows you to load lower quality images.

To give your visitors the appearance of a rapid load time, you might use image optimization strategies. It’s known as the “blur up” technique or “progressive pictures.”

Photos of significantly lesser quality are loaded first, followed by high-quality images. Your site visitors won’t be gazing at a blank page or a placeholder box where an image should be.

This approach enlarges a small portion of the image (typically around 40px) without becoming too complicated. As it loads, it creates a gaussian blur, which gives the image a soft-focus effect.

You may give your visitors the impression that your site is loading faster by loading a tiny or “blurred” image before the larger-sized one. Even if it takes a second or two for the image to come into focus, they know that it will materialize eventually.

Unfortunately, this technique can be a bit difficult to implement and requires some basic CSS understanding in order to succeed. To learn more about the “blur up” method, see CSS-Tricks.


7. Sites that use lazy loading are more efficient.

Lazy loading is another picture optimization approach that can speed up loading times. It works by delaying the loading of pictures until a visitor scrolls down to a certain point on a page.

It is possible to load pictures on a website in sequential order rather than all at once using lazy loading. This decreases the number of HTTP queries made to the server, allowing the page to load faster.

To install lazy loading on your WordPress site, you may utilize WP Rocket’s Lazy Load.

Your users will only see pictures on the website if they are currently accessible to them. In addition to lazy loading thumbnails, posts, and widget text with this plugin, you can also lazy load widget pictures using this plugin once you install and activate it. Best of all, the script used to do all of this is really little – it only takes up 10KB of memory.

This function is available if the user’s browser has it. In order to do this, you must update your site’s files and add code to them.

Add filter(‘rocket use native lazyload’, ‘__return true’);

To find the functions file, you can easily navigate to the Appearance then Theme Editor using the WordPress dashboard.

The functions.php file would be listed on the right side. Also, you may access it through the File Manager or an SFTP client.

Keep in mind that if you already have an image optimization plugin installed on your website, you may not need a specialized slow load plugin at all. Remember that Optimole, for example, has built-in slow load features?

The Beauty of an Optimized Image

Web pages come with decorative graphics. Online galleries and portfolios may enhance the aesthetic of your websites and improve the user experience for your visitors. Without proper optimization, quality pictures may be quite large and sluggish to load, affecting your site’s overall efficiency.

The following are seven strategies for optimizing pictures on your site:

  1. Choose the most appropriate picture file format for your needs from the options listed below.
  2. Your site’s current speed may be measured by comparing it to the benchmark.
  3. TinyPNG is a program that allows you to compress pictures to minimize file size.
  4. Before exporting your photos, you should resize them.
  5. With the use of a WordPress plugin such as Optimole, you may automatically optimize images.
  6. On your website, enable lazy loading.
  7. Use the “blur up” approach to load photos of lesser quality.
