Microsoft Paint is a simple and straightforward app for resizing images. To resize an image in Paint, it is recommended to make a copy of the original image and work on resizing the copy. This can be done by right-clicking on the image, selecting 'Copy' and then pasting the copy into a new file. The copied image can then be opened in Paint. Once the image is open in Paint, the 'Resize' button can be selected from the toolbar at the top of the window. In the 'Resize' window, the 'Percentage' option should be selected at the top, and the 'Maintain aspect ratio' box should be checked to prevent the image from becoming distorted. A percentage can then be entered to shrink or enlarge the image. While Paint is a useful tool, it does not support batch processing, so alternative tools such as Watermarkly may be preferable when resizing multiple images.

What You'll Learn

Copy the original image and paste it elsewhere
To resize an image in Microsoft Paint, it is recommended to first make a copy of the original image. This will ensure that you still have the image in its original size. To do this, right-click on the image, select "Copy," and then right-click on your desktop and select "Paste." Now you have a copy of the image that you can open in Paint and resize without modifying the original image.
Once you have copied and pasted the image, you can open it in Microsoft Paint. You can do this by right-clicking on the copied image and selecting "Open with," then choosing Paint from the pop-out menu.
With the image now open in Paint, you can begin the resizing process. Click the "Resize" button in the middle-right section of the toolbar at the top of the window. This will open the Resize window, where you can adjust the size of your image. Make sure that "Percentage" is selected at the top so that your changes will be measured in percentages. For example, changing the image's values to 75 will make it three-quarters of its original size.
Additionally, remember to check the "Maintain aspect ratio" box to prevent your image from becoming distorted. If you want to resize the image to a specific size in millimeters, you may need to adjust the resolution or canvas size instead of using the "Resize" option in Paint.
In conclusion, when resizing an image in Microsoft Paint, it is important to first make a copy of the original image by right-clicking and using the "Copy" and "Paste" functions. Then, open the copied image in Paint and use the "Resize" button to adjust its dimensions. Remember to keep the "Percentage" option selected and check the "Maintain aspect ratio" box to ensure your image remains proportional.

Open the image in Paint
To open the image in Paint, you first need to make a copy of the image you want to resize. This is important because you will be modifying the image, and you want to keep the original in its original size. Go to the image, right-click it, and select "Copy" from the drop-down menu. Then, right-click an empty space in the folder or on your desktop and select "Paste".
Now that you have a copy of the image, you can open it in Paint. Right-click on the copied image and select "Open with" from the drop-down menu. A pop-out menu will appear, where you can select "Paint". This will open your selected image in the Paint program.
Once the image is open in Paint, you can begin the resizing process. Click the "Resize" button in the middle-right section of the toolbar at the top of the window. This will open the "Resize" window, where you can adjust the size of your image.
It is important to note that reducing an image's size will also make the image's file size smaller. Additionally, enlarging an image will reduce its quality. Therefore, it is always a good idea to work on a copy of the image rather than the original file.

Ensure 'Percentage' is selected
When resizing an image in Microsoft Paint, it is important to ensure that "Percentage" is selected at the top of the Resize window. This will allow you to measure your image changes in percentages, rather than in exact pixel dimensions.
To do this, first open the image in Microsoft Paint by right-clicking on the image, selecting "Open with", and then clicking "Paint" in the pop-out menu. Once your image is open in Paint, click on the "Resize" button in the middle-right section of the toolbar at the top of the window.
In the Resize window, make sure that "Percentage" is selected. If not, click the circle next to "Percentage" to select it. This will ensure that your image changes will be measured in percentages. For example, if you enter 50, the image size will be decreased by 50%.
It is also important to note that you should check the "Maintain aspect ratio" box to ensure that your image does not become distorted. This will keep the width and height of your image in proportion as you resize it.

Check 'Maintain aspect ratio'
When resizing an image in Microsoft Paint, checking the "Maintain aspect ratio" box ensures that the image's proportions are preserved and it doesn't become distorted. This option is available in the "Resize and Skew" dialog box, which can be accessed by clicking the "Resize" button in the middle-right section of the toolbar or through the Ctrl+W keyboard shortcut.
By checking the "Maintain aspect ratio" box, you ensure that the image is scaled proportionally. If this option is not selected, changing one dimension, such as the height or width, will result in the other dimension remaining at its original value, potentially warping the image.
For example, if you have an image that is 1000 pixels wide and 500 pixels tall, and you only adjust the width to 500 pixels without the "Maintain aspect ratio" option checked, the height will remain at 500 pixels. This will distort the image, making it appear stretched or compressed.
However, with the "Maintain aspect ratio" option checked, changing one dimension will automatically adjust the other, keeping the image's proportions intact. In this case, reducing the width to 500 pixels will automatically adjust the height to 250 pixels, ensuring the image remains proportional and avoiding any unwanted distortion.
It is important to note that while checking the "Maintain aspect ratio" box helps prevent distortion, resizing an image, especially enlarging it, can still result in a loss of quality. Therefore, it is generally recommended to work with high-resolution images and create a copy of the original image before making any changes.
