Despite the enormous value and capability that GIMP (Gnu image manipulation program) provides, individuals frequently find it challenging to use. It makes sense because GIMP isn’t the most widely used image editor available.

While having many features is beneficial, it makes things more difficult for new users. But once mastered, GIMP is pretty potent.

This guide highlights how to resize an image in gimp’ in just 5 easy steps. So without a further due, let’s begin!

Step #1 Open An Image

The very first step towards resizing your image is to select the image and open it in the main window.

We will use a bird image as an example for this guide, and you can right-click and save it.

Tip

It’s a good idea to remove any dust, scratches, or noise from your image before enlarging it because these things could appear more prominently in the expanded version.

Step #2 Select Scale image

Next, click on the image menu on the top menu. A drop-down menu will appear on the screen. From the available options, choose Scale image.

Step #3 Adjust The Image Proportions In The Scale Image Dialog Box

While you have various options, the image size is currently configured to display pixels. Since it’s simple to cut your image in half or quarters without doing any math, the percentage option is the most practical choice.

Keeping your image size locked in its current aspect ratio is how the Scale Image dialog is set up by default. 

If you want to turn off this lock, click the grey “chain link” icon between the Width and Height boxes.

However, doing so can distort your image, so avoid doing so unless you absolutely must.

The default “Cubic” interpolation setting works well for most images when scaling 8-bit style pixel art or technical drawings. You can, however, play around with it and modify it as per your needs. 

Use the LoHalo or NoHalo interpolation settings on line drawings if you need extremely accurate results for engineering or scientific purposes, although they aren’t always the best option.

It’s crucial to remember that if you feel confused when examining all of the available options, you can always click the “Reset” button to reset everything to its default settings.

Step #4 Click Scale Tool Button

By clicking the Scale button at the dialog box’s bottom, you can choose your image’s new size after you’re satisfied with it. Your GIMP workspace’s picture will adjust to the new proportions.

If you change your mind or realize something isn’t quite right, you can always go back and start again by choosing Edit from the menu bar, selecting Undo Scale photo, or pressing the Ctrl+Z keyboard shortcut (Option+Z on macOS). 

If you don’t like the new settings, you can undo them and repeat the same steps as in step 3.

Step #5 Save Your Resized Image

Congrats, you have finally resized your image in Gimp. However, one last thing is yet to do- ‘Save the file.’

 The simplest approach is to continue with the same file type you started with, while there are numerous other file formats for saving photographs.

To save as a more popular file type like JPG or PNG, select Export from the File menu.

If you want to see a list of alternatives, pick the Select File Type (By Extension) icon. GIMP will presume that you wish to save the image in the same format you started with.

You can save in GIMP’s native XCF file format by selecting Save As from the File menu. However, this format can only be accessed by GIMP. It’s helpful if you’ve done more intricate editing, but it’s not required if you’re resizing your image.

Why Does Image Quality Degrade Upon Enlargement?

After image processing, many people face a common problem of image quality loss when they import the entire image on different platforms. The file size can go back to the default canvas size.

One of the most widely used image formats is ‘bitmap.’ Your whole collection of PNG and JPEG files are bitmap images. There are hundreds of pixels in a bitmap file. In closer fact, the pixels appear as squares when you zoom in.

The word “Bitmap” refers to the fact that each pixel is mapped to a particular place on the image.

 Mostly all the image editing software either increases or decreases the pixels to resize an image. Because of this, there is no discernible quality loss when resizing an image, mostly due to an even greater reduction in pixel visibility.

On the other side, these larger pixels become more noticeable when you resize a picture in WordPress to make it larger, giving the image a hazy and pixelated appearance.

GIMP is a free alternative to premium image editing software like Adobe Photoshop and Affinity Photo. Additionally, you can apply it to image enlargement with the least amount of quality loss. However, we should caution you that the outcome won’t be as good as Perfect Resize, which we’ll demonstrate in way 3 below.

To resize an image without losing its quality on Gimp, you must:

1.       Install Gimp from a safe site and not any third-party websites, which can affect your system after downloading. Always choose a stable and compatible version of Windows or MACOS.

2.      After installing Gimp, open the image and select scale image from the image drop-down menu.

3.      Now, enter the dimensions of your choice in the dialog box.

4.      This is an important step, go to a quality, browse interpolation method and select ‘cubic.’

5.      Lastly, click ‘scale’ to finish.

That’s all there is to it; you can now export the enlarged image in various formats, including PNG, JPEG, HTML, and more.

Conclusion

Now you see how easy resizing images is. One of the most frequent image modifications is resizing, which is a straightforward operation for those who utilize open-source software. GIMP makes it simple to manually adjust your image’s size or enter your own chosen measurements.
