How to optimise images for web online

31 October 2019

In this post I will show you a really simple (best of all free!) way to optimise images for web online. Doing this will speed up your website page loading time, and keep your customers from leaving you for your competition. I will be talking about how to make your website load super fast, and keep you ahead of your competition online. Not all of us are fortunate enough to have photo editing software like Photoshop or Lightroom, so here is a quick and easy guide on how to optimise images for web online. I will use this example photo:

Like I mentioned in my previous post the first thing to check is the size of the photo that you want to upload to your website or blog. To find this out select Properties from the menu and click on the Details tab in the Properties box. On a Mac, right-click (or hold down the Control key and click) the image thumbnail and choose Get Info.

It is 4000 Pixels wide and 2666 Pixels in height with a resolution of 300 Pixels/Inch, and it is a huge 5.4 MB – 5400KB. Uploading such large photos to your website will have a detrimental effect on how quickly your website or blog loads and this will have a direct impact on potential clients, people are impatient and will navigate away to another website if it takes too long to load.

There are numerous online photo editors, I chose Pixlr Online Photo Editor for my post. Once you have opened the Pixlr website you will see an Open Image tab, click on it and navigate to your photo, or drag it onto the webpage:

Once you have located the image, you will see this box:

The Open Image box will let you know that it is a huge image (especially for online purposes), but go ahead anyway and click on the Ultra HD box. Essentially this is the same size as the original image, you do not need to edit the resized image as we will resize when saving. the more times you resize an image, the more you will degrade the quality of the image. Click Ok and open the image.

Pixlr has numerous photo editing functions available, but all we need to know in this tutorial is resizing and optimising images for websites online. Once it is open all you need to do is save it, so go ahead and click save. A box will open.

Type in a width of 600 – this is a standard size for images to be used in a post or in your portfolio. Please check your website’s documentation or ask your webmaster what the optimum dimensions are for images on your website. They might vary slightly depending on the website.

The image height will automatically change as the proportions are constrained. lastly click DOWNLOAD. You now have an image that has been optimised for web and ready to upload. There is one extra step I suggest you take. I always finish off by uploading my images to TinyPNG – it is a really handy online tool to further reduce an image size, and the best part of it is that you cannot see the difference in image quality.

It is really easy to use, drag your downloaded image onto the page and wait for the green progress bar to complete.

Click download and the image is ready for you to upload onto your website or blog. Just to remind you I started off with a photo that was 5.4 MB – (5400KB) and ended up with it only being 22.9KB which is a whopper of a saving.
