How to Resize Image in Ubuntu For Free & Easy [2023 Update]

[updated on Apr 17, 2023] Have you upgraded from Windows or macOS to Ubuntu and missing MS Paint or Preview for reducing the size of the images? Then you are in the right spot! In this article, I am going to show you how to resize Image in Ubuntu for free and easily!

By reducing image size you gain two things. First, the image size (as in pixels) gets smaller so you can use it on social platforms or even articles or blogs. And secondly, the size (as in storage) also decreases so it will make the web page load faster. So 2 problems get solved.

If MS Paint was available on Ubuntu then this article would have made no sense. Since I went through this I know how frustrating it can get. It is so silly but it hurts when you download apps thinking it will work but they require some amount of terminal coding.

But today, I am sharing with you, a method that requires no strings of code to run! And also I assure you this is the most detailed article about how to resize image in Ubuntu! So without anything else, let’s get started!

Using GNU 2.10 to Resize Image in Ubuntu

To resize images in Ubuntu for free you need an app that’s called GNU Image Manipulation Tool. It is also known as GIMP. It’s not a sponsored article whatsoever, I use it on daily basis, in fact, the images used below are from the exact sample!

GNU Image Manipulation tool 2.10 is absolutely free to download. It’s a great application. I’ve been using it for a while now before sharing it with you. So you can be completely safe and download it.

To download GNU 2.10, all you need is to search for it in the Ubuntu Software Center. It’s a 400 MB application. And once it’s installed just launch it from the App Launcher or search for it.

It is a very powerful photo editing application, image resizing is very little work. You can say it’s an “alternative” to Photoshop in a broader sense. GIMP is an open-source photo editor that’s available on Ubuntu (Linux), Windows, and macOS. I would suggest if you use photo editing then you can give it a shot.

I am dividing the steps to resize images as pre and post. Pre as the name applies will tell you exactly everything you have to do to successfully resize the file size. and in the post, the steps to have a successful export of the file. So let’s begin with the pre.

Steps to successfully Resize The Image Size (Pre)

Once GNU Image Manipulation Program is open you have to follow a few steps.

#1 Click on File and press Open. You can alternatively do that with Ctrl+O.

#5 Now you have to Scale Image. if you plan to upload these images on your website then stick to the px marked in yellow below. Now, what size to choose in Width and Height? From the above point, if you are going to use the resized images on a blog post or website then the image can be up to 800 px width in the landscape. Always remember; the lower the image px count lesser the image size will be.

The height will be automatically adjusted for a perfect aspect ratio. In the same way, if the image is portrait then lowing the height should be preferred. For height, I usually pick 300 or a max of 400 px. Rest you can try and explore!

Once you have selected the px value (either width or height) press the px button next to it so that the other unchanged value gets in the proper aspect ratio. Usually with 800px width height is 600.

#6 Now you will have a very small preview of the image. Don’t worry this is not the final size! Change the value from 25 to 100 percent pointed with a green pointer.
