What You'll Learn

Make a copy of the image
Before resizing an image in Paint, it is important to make a copy of the original image. This ensures that you still have the image in its original size and quality, as resizing the image will modify the original file.
To make a copy of the image, go to the image file and right-click on it. In the drop-down menu, select "Copy". Then, right-click on an empty space in the folder or on your desktop and click "Paste". This will create a copy of the image in the selected location.
Now that you have a copy of the image, you can proceed to open it in Paint. Right-click on the copied image and select "Open with" from the drop-down menu. Choose "Paint" from the pop-out menu, and the copied image will open in the Paint program.
With the image open in Paint, you can now begin the process of resizing it. Click on the "Resize" button, which can be found under the "Image" section in the Paint toolbar. Ensure that "Percentage" and "Maintain Aspect Ratio" are selected, as this will preserve the proportions of your image.
Finally, enter a percentage between 1 and 500 in the "Horizontal" text box to shrink or enlarge your image. For example, entering 75 will result in the image becoming 3/4 of its original size. Once you are happy with the new size, click "OK" to apply the changes.

Maintain aspect ratio
When resizing an image in Microsoft Paint, it is important to maintain the aspect ratio to prevent the image from becoming distorted. To do this, first, make a copy of the image you want to resize so you can keep the original. Then, open the image in Microsoft Paint and click the "Resize" button in the toolbar at the top of the window.
In the Resize window, ensure that "Percentage" is selected at the top so that your image's changes will be measured in percentages. You can then change the image's values to a percentage less than 100, for example, changing the values to 75 will make the image three-quarters of its original size.
To maintain the aspect ratio, make sure that the "Maintain aspect ratio" box is checked. This ensures that any changes you make to one aspect of the image, such as the vertical size, will also scale with the other aspects. If you know the exact horizontal or vertical pixel count you want, you can select "Pixels" instead of "Percentage" and enter the desired values. However, if you select this option, you may need to uncheck the "Maintain aspect ratio" box to set your desired dimensions.
If you are resizing the image by dragging it with your mouse, you can hold the Shift key while dragging to preserve the aspect ratio. Alternatively, you can open the image's resize window and change the amount there.
