GIMP is a free photo editor for computers. If you try to search for a resize tool in GIMP, you won’t find one. That’s because it doesn’t exist. However, it doesn’t mean that you can’t resize images in GIMP. Whether you are looking to change an image’s dimensions or its file size, this post will help you resize images in GIMP.
Let us begin.
1. How to resize an image by changing the file size
Many websites and applications have image size limitations. If you want to change the file size of an image, you will need to reduce its quality as shown below.
one. Open the image in GIMP by going to File> Open.
two. When the image opens in GIMP, go to File> Export As.
3. The Export Image dialog opens. Enter a name for the image (or use the same) and click To export.
Four. You will be greeted by Export image window. Here you need to reduce the value of the Quality option using the slider to decrease the size of the image file. Click on To export to save the image.
Tip: Select the check box next to Show preview in image window to see the file size.
2. How to resize an image by changing the dimension
You can change the resolution of an image in three ways, as shown below.
1. Using the Scale tool
To resize images in GIMP, you need the help of the Scale tool. These are the steps:
one. Open the required image in GIMP by going to File> Open.
two. Click on the Image option in the menu bar and select Image scale from the menu.
3. The Scale Image window will open. Here you will get the Image Size option with two fields: Width and Height. The default size is displayed in pixels. If you want to view it in a different format, click the px drop-down box and choose from percent, inches, etc.
Enter the required dimensions of the image in the Width and Height fields. If you want to decrease the size of the image, enter dimensions less than the current number. Similarly, if you want to scale the image up, enter a larger value. Be aware that enlargement may cause loss of image quality.
Another thing to keep in mind is locking the aspect ratio. In doing so, if you change one value (width or height), the other value will change accordingly, resulting in an image that won’t stretch or compress in an odd way. The aspect ratio is locked by default. To verify, check the chain icon next to the Width and Height boxes. It should be locked. If it isn’t, click on the chain to lock it.
Keep the interpolation quality as cubic. However, if you notice any distortion in the image, try other interpolation methods. Finally, click on the Scale button.
Four. To save the image in a new resolution, click File> Export As. Enter a name and select the image quality as shown in the previous method.

2. Scale using the mouse
You can also resize an image manually with the help of a mouse.
one. Upload the image to GIMP.
two. Click on the Scale in the toolbox or use the Shift + S keyboard shortcut.
3. Hold down the Ctrl key and mouse button and pull the image inward from any corner. The size of the image will continue to decrease as you compress it. Leave the buttons at the desired size and click Scale in the pop-up window. Similarly, stretch the image outward to increase its size.
Four. When you reduce the size of the image, you may see the blank canvas underneath. To remove it, click Image> Crop to Content.
5. Click on File> Export As to save the image.
3. Resize the layer
If you have multiple image layers, using the above methods directly will sometimes resize the entire image instead of just an individual layer. You can resize a single image layer with the help of the Scale tool or by using the Layer Scale feature. These methods can also be used to resize pasted images.
Note: Make sure the selected layer is a normal layer and not a floating layer. In case it is a floating layer, right click on it in the Layer panel and select the “To new layer” option.
1. Using the Scale tool
one. Select the layer you want to resize by clicking on it in the Layer panel.
two. Once selected, click the Scale in the toolbox to enable it.
3. You will see the Scale options in the right or left pane. Please select Cap next to Transform.
Four. Now, press the Ctrl key and the mouse button together and compress or stretch the image using its borders. Click on the Scale in the pop-up window. Your cape will change in size.
2. Using the scale layer
one. Click the layer in the Layer panel to select it.
two. Go to the Cap option in the menu bar and choose Scale layer from the menu.
3. Enter the new dimensions of the image in the available fields. Make sure the chain icon is locked to keep the aspect ratio. Click on Scale.
Similarly, you can resize other image layers.
