How to Resize an Image in Microsoft Paint
This wikiHow teaches you how to enlarge, shrink, or crop an image in Microsoft Paint. The first two maintain the native aspect ratio while the latter removes the outer area from the image.
Part 1Enlarging or Shrinking an Image
1Go to the image you want to resize, right-click it, and click Copy in the drop-down menu, then right-click an empty space in the folder or on the desktop and click Paste. Failing to make a copy of the image will result in the original image being modified.
2Doing so will prompt a drop-down menu.
3This option is toward the middle of the drop-down menu. A pop-out menu will appear.
4It's in the pop-out menu. Doing so will open your selected image in the Paint program.
5This option is on the middle-right side of the "Image" section at the top of the Paint window.
6If not, click the circle next to "Percentage" to ensure that your image's changes will be measured in percents. Your image will start at 100 for both the vertical and horizontal values, so changing these to "75" will reduce your image to three-quarters of its original size. If you know the exact horizontal or vertical pixel count you want, you can click the circle next to "Pixels" instead.
7If there is no checkmark in the box next to "Maintain aspect ratio", click the box; otherwise, any changes you make to one aspect of your image (e.g., vertical size) won't scale with the other aspects. If this box is already checked, proceed to the next step.
8Type a number between 1 and 500 into the "Horizontal" text box. Any number below 100 will cause your image to shrink while maintaining its dimensions, and any number over 100 will enlarge the image while maintaining the dimensions. If you're resizing using pixels, type the number of vertical pixels you want to use into the "Vertical" text box. You can also uncheck the "Maintain aspect ratio" box and enter a different number than was initially used in the "Horizontal" text box if necessary.
9Doing so will apply your changes to the image.
10Press Ctrl+S to do so. This will save your changes to the image.
Part 2Cropping an Image
1Cropping an image can only result in a smaller section of the image, but the cropped section will retain its quality. This is ideal if you're trying to remove excess parts of your photo while maintaining its resolution. Cropping an image will also make the image's file size smaller.
2Go to the image you want to resize, right-click it, and click Copy in the drop-down menu, then right-click an empty space in the folder or on the desktop and click Paste. Failing to make a copy of the image will result in the original image being modified.
3Doing so will prompt a drop-down menu.
4This option is toward the middle of the drop-down menu. A pop-out menu will appear.
5It's in the pop-out menu. Doing so will open your selected image in the Paint program.
6Select is in the "Image" section of the Home tab at the top of the "Paint" window. A drop-down menu will appear.
7It's the first option in the drop-down menu here. If you want to be able to draw your own selection, click Free-form selection instead.
8Doing so will drag a rectangular dotted line over the image; anything inside of the dotted line will remain when you crop the image. If you're trying to remove a border from a photo, the best way to do so is to click in the top-left corner and drag diagonally into the bottom-right corner (or similar). To remove the dotted line and start over, click anywhere outside of the area surrounded by dotted lines.
9It's at the top of the "Image" section of options and to the right of Select. Clicking this button will remove everything outside of the dotted lines, leaving only the part of the image that's inside.
10Press Ctrl+S to do so. This will save your copied image as a cropped file rather than as the original image.
