Resizing pixel art can be tricky, especially when trying to avoid the blurring effect that often occurs when scaling up or down. This effect is due to the interpolation method used by most editing software, which causes pixels to merge and creates a blurry appearance. Old editing tools like Microsoft Paint in Windows XP handled pixel art resizing well, but modern software may require additional steps to achieve a sharp result. To maintain the integrity of pixel art when resizing, it's crucial to use the correct settings and techniques. This includes disabling features like anti-aliasing in Photoshop or choosing the Point option in Unity to preserve the sharpness of your artwork. Additionally, ensuring that your image is sized to exact pixel measurements and using a limited colour palette can help reduce blurring when resizing.

Use Microsoft Paint on Windows XP to resize pixel art without blurring
Microsoft Paint, found in Windows XP, is a great tool to handle pixel art when scaling up or down an image without blurring. Here is a step-by-step guide on how to resize pixel art without blurring using Microsoft Paint on Windows XP:
First, make a copy of the pixel art 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 choose "Paste." This step is essential to ensure that the original image remains unmodified.
Now, right-click on the copied image and select "Open with" from the drop-down menu. Choose "Paint" from the pop-out menu to open the image in the Paint program.
Once the image is open in Paint, click on the “Resize” button in the middle-right section of the toolbar at the top of the window. Ensure that "Percentage" is selected at the top of the Resize window so that your resizing adjustments will be measured in percentages.
For example, if you want to resize the image to 75% of its original size, change the values to 75. Additionally, make sure to check the "Maintain aspect ratio" box to prevent the image from becoming distorted.
Finally, type the desired percentage between 1 and 500 into the "Horizontal" text box to shrink or expand the image. Click "OK," and your image will be resized without blurring the pixel art.
By following these steps, you can use Microsoft Paint on Windows XP to effectively resize pixel art while preserving the sharpness and clarity of the pixels.

Switch off 'anti-aliasing' in Photoshop to avoid blurring
When resizing pixel art, you may encounter blurring issues due to the default anti-aliasing settings in image editing software. Anti-aliasing softens the edges of objects in digital images, but it can cause unwanted blurriness when working with pixel art, where crisp edges are essential.
In Photoshop, you can switch off anti-aliasing to avoid blurring when resizing or editing pixel art. Here are several methods to achieve this:
Using the Pencil Tool
Instead of using the Brush Tool, switch to the Pencil Tool. The Pencil Tool creates hard-edged strokes with no anti-aliasing, resulting in crisp pixel art lines.
Adjusting Image Resampling Settings
Go to Photoshop Preferences > General and set the image resampling setting to "Nearest Neighbor." This ensures that when you resize or transform objects, Photoshop defaults to the "Nearest Neighbor" algorithm, which preserves the crisp edges of pixel art.
Working with Color Palettes
Before starting your pixel art project, define a color palette with specific colors. When you work with this palette, any strokes or brushes you use will be full pixels with no anti-aliasing. This method provides a more controlled approach to creating pixel art without blurring.
Using the Lasso Tool
When cutting out images with crisp edges, consider using the Lasso Tool. Unlike some other selection tools, the Lasso Tool allows you to turn off anti-aliasing, giving you more control over the edges of your selections.
Converting Vector Shapes
If you're working with vector shapes, you can convert them into turned-off anti-aliased shapes. This process involves unchecking the "Anti-alias" option in the Options Bar when pasting or transforming a Vector Smart Object.
Using Illustrator to Export as PNG
If you're working with Adobe Illustrator, you can export your artwork as a PNG file and choose "None" for the anti-aliasing option. Then, import this PNG file into Photoshop, ensuring that the crisp edges of your pixel art are maintained.
By following these methods, you can effectively switch off anti-aliasing in Photoshop and avoid blurring when working with pixel art.

Use the 'Nearest Neighbour' option in Photoshop for sharp pixel art
When resizing pixel art, you may encounter blurring issues due to the default interpolation settings in most image editing software. To maintain sharp edges in your pixel art when resizing, you can use the Nearest Neighbour option in Photoshop.
Nearest Neighbour interpolation preserves the edges of pixel art by preventing pixels from "merging" with each other during resizing. This method prioritises speed and the preservation of sharp edges over higher quality smoothing algorithms, which may introduce blurring.
To use Nearest Neighbour interpolation in Photoshop, you will need to adjust the settings. Firstly, navigate to Preferences > General > Image Interpolation. Here, you can set the interpolation method to Nearest Neighbour. Alternatively, if you are using Free Transform, the interpolation method can be selected from the Options Bar at the top of the screen.
It is important to note that this method will affect all raster layers and layer masks, but not Smart Objects, Type Layers, or Shape Layers. If you are working with Smart Objects, you will need to use the Preferences > General > Image Interpolation method instead.
By utilising the Nearest Neighbour option in Photoshop, you can resize your pixel art while maintaining sharp edges without the blurring effect typically associated with image resizing.

Convert the image pallet to index and minimise colours
To convert an image into pixel art, you will need a graphics editor software with the ability to resize an image, adjust brightness and contrast, and a "magic wand" select-by-colour tool with adjustable tolerance. Some common programs with these features include Inkscape, GIMP, and Paint.Net.
When converting an image into pixel art, it is important to reduce the number of colours in the image. This can be done using the Posterize filter, which recolours an image using a specified number of colours. In Paint.Net, for example, you can control the maximum number of RGB values available.
Another way to minimise colours is to use a limited-colour palette indexing software like "Pixelator". This software allows you to specify the number of colours you want to use and will automatically convert your image into pixel art.
If you are using Python, you can use the Python Image Library (PIL) to convert an image to a specific indexed palette without dithering, which can distort outlines and add noise to flat areas. The code to do this is:
Python
From PIL import Image
Def quantizetopalette(silf, palette, dither=False):
"""Convert an RGB or L mode image to use a given P image's palette.""""
Silf.load()
Palette.load()
Im = silf.im.convert("P", 0, palette.im)
Return silf._new(im)
Additionally, you can use online tools such as Pixel Art Village to convert any image or picture into pixel art. This website allows you to modify the pixel size and apply custom palettes to the image.

Use a higher DPI to allow for more freedom when resizing
When resizing pixel art, one crucial factor to consider is the DPI (dots per inch). DPI is used to convert physical dimensions into pixel resolution and vice versa. While DPI doesn't directly enhance the quality of the artwork or the print, it plays a vital role in ensuring the desired print size and quality.
For pixel art, the relevance of DPI primarily comes into play when printing. To achieve a high-quality print comparable to photographic standards, a minimum DPI of 300 is recommended. This means that for a canvas with a width of 4000 pixels, the largest print size possible without compromising quality would be approximately 13.3 inches.
The relationship between DPI and pixel size is inversely proportional. As DPI increases, the density of pixels per inch rises, resulting in smaller pixels. For instance, at 1 DPI, there is 1 pixel per inch, whereas at 2 DPI, there are 2 pixels per inch, and so on. Therefore, a higher DPI leads to a higher-resolution image but also makes the overall image smaller.
To maintain the desired physical dimensions of your print while working with higher DPIs, it's essential to adjust the pixel resolution. By increasing the pixel resolution, you can ensure that your image will fit the intended print size without losing quality. Most drawing applications will automatically perform these calculations for you, making it easier to achieve the desired results.
Additionally, when working with pixel art, it's important to be mindful of the scaling methods employed by various software tools. Some modern editing software tends to apply a "blurry" effect when scaling images up or down because pixel art is less commonly used. To avoid this issue, certain software allows you to disable the anti-aliasing feature, preserving the sharpness of your pixel art.
