In this post, we will show you how to blur or pixelate an image on Windows 11/10. If you want to hide part of an image from the viewers, you can blur or pixelate that part, leaving the rest of the image intact. The blur effect fades that specific part into the background, bringing the rest of the image into focus (and vice versa). Pixelate effect stretches the image to a point where individual pixels become visible. Both of these photo effects work like charms to conceal specific parts in an image, such as a face or some other sensitive part or information that you don’t want to disclose to the viewer.
Pixelated and blurry are two different things, though they may appear similar. Blur happens when the image appears to be out of focus, whereas pixilation happens when the pixels that make up the image are stretched to an extent that they become visible to the naked eyes. Pixilation creates a jagged effect in the image as compared to blur, which creates a soft grainy effect.
How to Blur or Pixelate an Image on Windows 11/10
In one of our previous posts, we’ve covered the best free online tools that let you blur or pixelate images. In this post, we will show you how to blur or pixelate an image on Windows 11/10 using Windows built-in apps and some third-party image editing software for PC. Here’s the list of tools we are going to cover in this article:
- Microsoft Paint
- Microsoft Word/PowerPoint
- Photoshop Express
Let us have a look at how these tools can help in blurring or pixelating part of an image, or the entire image.
1] Microsoft Paint
MS Paint is Microsoft’s classic image editing software that comes pre-installed in all versions of Windows. It offers some basic image editing functions, such as crop, resize, flip, rotate, and annotate. Though it doesn’t have a dedicated blur or pixelate feature, if you want to blur an image without downloading a specialized tool, you can use a simple trick to create a pixelate effect in images using MS Paint. Here’s the trick:
- Launch MS Paint.
- Open the desired image in MS Paint using the File > Open option.
- Select the area that you want to blur using the ‘Select‘ tool listed in the toolbar. You can choose between Rectangular or Free-form selection.
- Take your cursor to the bottom-right corner of the selection.
- Click and hold, and drag the selection inwards.
- Decrease the size of the selection to about 10% of its original size.
- Do not deselect.
- Now again take your cursor to the bottom-right corner of the selection.
- Drag it outwards to bring it back to its original size. This will create a pixelated effect on the selected area.
- Repeat steps 3-9 to deepen the effect.
Keep in mind that this is just a trick and not a permanent solution to blur images. If you want a proper blur effect, move to the next option.
2] Microsoft Word/PowerPoint
Both Microsoft Word and PowerPoint feature a Blur artistic effect that can be applied to the images used in Word or PowerPoint. If you occasionally need to blur an entire image, you can use either of these software, which are part of the Microsoft Office suite that you might already be having on your Windows 11/10 PC. Here’s how you can blur images using Microsoft Word or PowerPoint:
- Launch Word or PowerPoint.
- Open a blank document or presentation.
- Insert the desired picture in the document or presentation using the Insert > Pictures option.
- Go to the Picture Format tab.
- Under the Adjust section, click on the Artistic Effects dropdown.
- Select the Blur effect (fifth option in the second row).
- To modify the blur effect, select the Artistic Effects options. A panel will appear on the right.
- Adjust the Radius slider to increase or decrease the blur effect.
You can also create this blur effect in Microsoft Word/PowerPoint using the Picture Correction options as explained below:
- Select the picture.
- Switch to the Picture Format tab.
- Click on the Corrections dropdown within the Adjust section.
- Select ‘Picture Correction Options…‘.
- In the Format Picture panel on the right-hand side, move the Sharpness slider to the left till you get the desired blur effect.
Note: The blur effect works on the entire image in MS Word/PowerPoint. In case you want to blur only a specific part, you can use MS Paint or download one of these image editing tools we are going to suggest next.
