Microsoft Paint is a simple image viewer that can be used to resize images. While it is a straightforward and accessible tool for Windows users, resizing images in Paint can result in a loss of quality. This is because resizing an image involves throwing away data and inferring what one pixel should look like based on the original image, leading to a definite loss of quality. The level of quality reduction depends on the method used to resize the image, and more advanced tools may produce better results. Additionally, the format of the saved image can impact quality, with JPG files losing quality each time they are opened or resaved, while BMP files store every pixel with no generation loss but result in larger file sizes.

What You'll Learn
Resizing photos in Paint
Resizing photos in Microsoft Paint is a straightforward task. It is a simple picture viewer that allows you to resize images by changing the pixel dimensions. However, it is important to note that resizing an image in Paint will reduce its quality. This is because the image is losing information as you are throwing away data and inferring what one pixel should look like when it was previously represented by two pixels. The level of quality reduction depends on how you resize the image.
To resize an image in Paint, first, make a copy of the image you want to resize. Go to the image, right-click, and select "Copy" from the drop-down menu. Then, right-click in an empty space in the folder or on the desktop and select "Paste". Now, right-click on the copied image and select "Open With", followed by "Paint".
Once the image is open in Paint, click "Resize" under the "Image" section in the toolbar. Here, you can enter new values for both the width and height of the image. However, if you change both the width and height, the original aspect ratio will not be maintained, and the image may appear stretched. If you only change one dimension, Paint will automatically adjust the other to maintain the aspect ratio.
Another way to resize the image is to drag a selection box over the area you want to keep. To do this, click on the "Select" option in the "Image" section of the Home tab. Choose "Rectangular selection" from the drop-down menu, then click and drag over the image to create a dotted selection box. Anything inside the box will remain when you crop the image. Once you are happy with the selection, click "Crop" in the "Image" section of the toolbar.
After resizing the image, go to "File" > "Save As" and choose a file format for your image. It is important to note that certain file formats, such as JPG, will lose quality each time the file is opened and re-saved, while others, like BMP, will not lose quality but result in a larger file size.

Loss of quality
Resizing a photo in Paint can lead to a loss of quality. While Paint is a convenient tool for quick and easy resizing, it is a simplistic image viewer that does not offer advanced features for preserving image quality.
When resizing an image, the data representing each pixel is altered, resulting in a loss of information. This loss of information leads to a visible reduction in quality, with potential artefacts such as rugged edges or blurring. The level of quality reduction depends on the method used for resizing. More advanced tools may add blurring instead of creating artefacts, which can be mitigated through subsequent sharpening techniques.
The file format also plays a role in quality retention. Saving a resized image in JPG format, for instance, introduces generation loss due to its lossy compression algorithm. Each time a JPG file is opened and resaved, it loses quality, irrespective of any modifications. In contrast, BMP maintains quality as it stores every pixel without compression, but results in larger file sizes. Other formats, such as PNG, offer lossless compression, balancing file size and quality preservation.
To minimise quality loss, it is recommended to resize a copy of the original image. Additionally, maintaining the aspect ratio during resizing can help prevent the image from appearing stretched or distorted. While Paint offers basic resizing capabilities, alternative tools like Watermarkly provide more advanced features for upscaling and batch-processing multiple images, resulting in better quality outcomes.
In summary, resizing photos in Paint can lead to a loss of quality due to data and pixel alterations. The level of quality reduction depends on the resizing method and the chosen file format. To preserve quality, it is advisable to use specialised tools, maintain aspect ratios, and prioritise lossless file formats.

Cropping photos
To crop an image in Paint, first, make a copy of the image you want to edit. This ensures that the original image remains unmodified. Then, open the copy with Paint.
Once the image is open in Paint, you can use the mouse to draw a frame around the area you wish to keep. This can be done by clicking and dragging the mouse to create a rectangular dotted line. Anything inside the dotted line will remain after cropping, and anything outside will be cropped out. You can also remove borders from photos by clicking and dragging diagonally from one corner of the image to the opposite corner.
After you have selected the desired area, click "Crop" in the "'Image'" section of the toolbar. This will remove the outer area of the image, leaving only the selected portion. The cropped image will retain its quality and have a smaller file size.
It is important to note that while Paint is a useful tool for basic image editing, it is a simplistic program and may not offer the same functionality as more advanced graphic design software. Additionally, the quality of the cropped image may depend on the format you choose to save it in, with some formats like JPG being lossy and losing quality each time the file is opened and resaved.

Changing pixel dimensions
Changing the pixel dimensions of an image is often necessary before uploading it to social media. Decreasing the pixel dimensions will also reduce the file size, but not drastically. To significantly reduce the file size, you will need to compress the image.
You can change the pixel dimensions of an image using Microsoft Paint. This is a simple and straightforward app that is available on all versions of Windows. To change the pixel dimensions of an image in Paint, first, make a copy of the image you want to resize. Then, open Paint and go to File > Open, and choose the image. Next, drag the area you want to resize with your mouse or press Ctrl-A to select the entire image. Right-click on your selection and choose the option to resize your image. Change the percentage to pixels and enter the desired dimensions. You may need to uncheck the "maintain aspect ratio" box to set the exact dimensions you want. Finally, save the image as a PNG file.
It is important to note that resizing an image in Paint may reduce the quality of the image. This is because the resize function in Paint creates artefacts, such as rugged edges. More advanced image editing tools generally add blur when resizing, which can be reduced through subsequent sharpening. Additionally, the JPG file format will lose quality each time the file is opened and re-saved, while BMP maintains the quality of the image but results in a larger file size.
If you are looking to resize multiple images or make an image significantly larger, you may want to consider using a different tool such as Watermarkly, which can handle upscaling and batch processing.

Alternative tools
Resizing a photo in Paint will reduce the quality, with the level of reduction depending on how you do it. While Paint is a quick and easy way to resize images, simple tools like Paint are prone to creating artifacts, such as rugged edges.
There are alternative tools that can be used to resize images, which may produce better results than Paint.
- More advanced tools: These tools generally add blur to the image when resizing, which is often unavoidable. Subsequent sharpening can help reduce the blur.
- Image viewers with higher quality resizing algorithms: Some image viewers have higher or lower quality resizing algorithms, which can achieve better or worse results than Paint.
- Image resizers: If you are just viewing the images, using an image resizer is not recommended as it will degrade the image quality. However, if you need to resize the image for a specific purpose, such as setting a desktop background, an image resizer can be used.
- Image editing software: There are various image editing software available that offer more advanced features and controls for resizing images, such as Adobe Photoshop or GIMP. These software often provide more precise control over the resizing process and may produce better results than Paint.
