How to reduce image size without losing quality on a Chromebook

If you take photos on your phone the image dimensions are most likely pretty high if you have a decent camera. This means there may be many occasions where you need to reduce the image dimensions of the photos you’ve taken. You may need to upload them to a blog for example or perhaps you want to use them in a document and the high image dimensions are not needed.

I’m referring to changing the dimensions of the image, and not reducing the file size of the image, which is a totally different subject. If you regularly reduce the dimensions of an image on your Chromebook you may be shocked that depending on how you do it can impact the quality of the image.

Enlarging an image from its original size will always impact the image quality. However, when it comes to reducing an image it should not have too much of an impact on the end result. What I’ve found is that it all depends on what software you use to reduce the image.

Using the Chrome OS built-in image editor

It took me a while before I realised that the ChromeOS built-in image editor isn’t a great option for reducing the dimensions of an image. It’s really easy to do as it’s simply a case of opening up an image and changing the image dimensions. The issue is the built-in image editor doesn’t give great results when reducing image dimensions.

I’m not really sure why this is the case because as I’ve already said reducing an image should not have too much of an impact on quality. However, what software you use to reduce the dimensions of an image on your Chromebook will have a huge impact on the end result.

Therefore, I would avoid using the ChromeOS image editor to change image dimensions. There are many other software options you have available to do the job. I’ll cover three other options you have available that offer better end results.

Other methods to reduce image dimensions on ChromeOS

The other methods we’ll look at all produce a decent image with reduced dimensions. The option you choose will obviously depend on what is most suitable for you. One option you have is to use Snapseed, which is an Android app created by Google. All Chromebooks available today are capable of running Android apps, so you should be able to install Snapseed without any issues.

Another option is to use Google Slides, which is available on your Chromebook as it’s part of the Google Office suite. This is a slightly longer method because you need to manually set the pixel dimensions of your presentation, and then import the image into the slide. This also means you’ll need to check what dimensions to set if you want to maintain the aspect ratio.

The last option is to use Squoosh, which is another app created by Google and is available directly from your Chrome browser. Squoosh wasn’t specifically made to edit photos or change image dimensions, as its main purpose is to reduce the image’s file size rather than dimensions. That being said, there is an option in Squoosh to change your image dimensions and it offers great results.


I’ve created a video, which you’ll find above, which shows you how to use all of the methods discussed. This will clearly show you why the ChromeOS image editor isn’t a good choice to reduce the size of an image.

You will also see other benefits to using the other methods discussed. One is that all of the other methods provide you with a file with a much smaller file size. Obviously, all different software tools use different compression rules. However, as you will see in the video. The ChromeOS image editor offers the worst results, but to make matters worse, it also takes up the most storage space.
