Walkthrough: How to optimise images for mobile

Google now looks at your ‘mobile first’ when deciding your website ranking. One of the key ways to improve your ranking is to improve your page load speed. When improving the load speed of any webpage the first thing to do is Optimise your Images. Images are the main culprits for slowing down a web page as they generally have a large file size and often unnecessarily so. So how do we Optimise Images?

Go to Page Speed Insights

Visit and enter your website address:





Next you will see a quick overview of your page speed. By default your mobile score is shown first.


Your Mobile Speed test



Scroll down until you see the heading ‘Optimization Suggestions’. Beneath this again is the sub heading Optimize images with a link to ‘Show how to fix’



Click on the text ‘Show How to Fix’ and the page will list a summary of images below that can be optimised (reduced in size with minimal loss to quality)


Beneath this again, you can see the text ‘Download optimized image’.
Clicking on the word ‘image’ will download a .zip folder to your computer containing all the optimised imagery.





Now its time to replace all the old bulky images on your site with your new speedy optimised ones. Run the test again and see your score improve.




Note, some loss to image quality may occur but the flip side is you have fulfilled one of Google’ most basic criteria and worked towards your site ranking better in search results.


In Summary.

This is the quickest way to optimise images and keep Google super happy but there is more you can do. This process simply compresses your image as much as possible it doesn’t resize the width or height. If you have uploaded an image that is 2000px wide and it only displays on your page at 1000px wide, then you should resize this image first to further increase your page speed.

resizing website imagery





‘Open’ a photo to choose one from your computer. Once you have selected your image a toolbar of options appears to the left…



The first two tools are Crop & Resize. I always resize my image first and then crop it to the required dimensions.


Resizing your image.

Images that are too big will slow down your web page. Find out the largest width your image needs to be displayed at and resize down to that pixel(px) amount.



Always ensure that ‘Lock aspect ratio’ is ticked so that your image doesn’t get stretched. Don’t worry if your height is too big, we will crop this next.

Be careful when making a small image bigger as this will result in a loss of quality and may appear pixelated, better just to find an image large enough to do the job.

Cropping your image.

Cropping is the most important tool when trying to make your image the correct size. It allows you to extract a portion of the image in whatever size you need without distorting the image. For example if your website layout needs a square shaped image but your desired image is rectangular, then you can crop out a square shape and trim away the leftovers. It’s best to find out the exact image size required for your layout and just type them into the required fields.



As well as typing in dimensions you can also drag visual guides to your desired size. Have a play around with the options as this will soon become your new best friend!


Save your image

And that’s it. Click on save up the top of your screen and save the image to your computer ready for upload to your website.

Some other tools for resizing imagery

The above tool, BeFunky, is all you need for resizing & cropping but here’s a quick overview of some more online tools I recommend on a regular basis.


Shutterstock Editor

This is very similar to but offers more in terms of design and also gives you some quick templates for creating facebook covers, twitter headers etc. You have to create a free account to use the tools but this is a handy image editor for making quick mock ups.

This is a free online tool based on photoshop. It is more advanced than the tools mentioned above but offers so much more once you get the hang of it. If you are doing a lot of image editing it is worth your while learning the basics. Photopea really comes into its own when you have to quickly resize multiple images to certain dimensions.


Photo Razor.

This is a tool we use a lot in the web industry when we want to reduce the size of an entire folder of images for example a folder of product images that are all way too large to display on web. It allows you to select a folder, set the max width and click go! This is great for bulk resizing of images but not cropping

Photo Razor can be downloaded for free from softsonic here.
