Blurring Photos 101: Mastering Partial Blurs In Ms Paint

how to blur part of a photo in paint

Blurring parts of a photo is a useful skill to have, especially when you need to censor or hide something in an image. While it is possible to do this in Paint 3D, Microsoft Paint does not have any extended features that allow you to blur parts of an image. However, there are workarounds to achieve a similar effect. One method is to use shapes to cover the area you want to blur, and then adjust the transparency and edges of the shape to blend it into the image. Alternatively, you can use other software such as Paint.NET or online editors like sumopaint.com, which offer more advanced features such as a blur tool that can be applied to specific areas of an image.

Use Paint 3D

To blur part of a photo in Paint 3D, follow these steps:

  • Launch the Paint 3D app on your Windows 10 PC and open the image you want to edit. You can do this by clicking on "File" and then "Open," or by using the "mspaint" run command (Windows key + R) to open MS Paint.
  • Click on the "Select" tool present under the "Brushes" tab.
  • Select the portion of the image you want to blur by dragging the selection box around it.
  • Using the bottom right corner of the selection box, drag it inwards to decrease the size of the selection. Make it very small, but ensure that it is still large enough to be resized again.
  • Once you have made the selection small enough, increase the size again to fit the original area. The selected part of the photo will now be blurred.

It is important to note that Paint 3D does not have a dedicated blur option, so the process is a bit tricky and may not produce the neatest output. However, with a bit of practice, you can use this method to blur portions of your images and make them suitable for sharing on social media or messaging apps.

Additionally, if you want more control over the blur intensity, you can repeat the resizing process a few more times to increase the blur effect.

Insert a shape over the desired area

To blur part of a photo in Paint, you can insert a shape over the desired area. Here's a step-by-step guide:

  • Open your photo in Paint.
  • Go to the Insert tab and select Shapes from the menu.
  • Choose a shape from the gallery that best fits the area you want to cover. You can select standard shapes like rectangles, ovals, or triangles, or draw a freeform shape if you need something more custom.
  • Click and drag to draw the shape over the desired area.
  • With the shape selected, go to the Shape Format tab.
  • Select Shape Fill and choose a suitable color for the shape. You can match the color to the surrounding area of the photo to help it blend in.
  • To remove or change the border of the shape, select Shape Outline. Choose No Outline or select a border color that matches the image.
  • To soften the edges of the shape and create a smoother blend with the image, select Shape Effects and then Soft Edges. Adjust the variation to achieve the desired blur effect.
  • After applying the soft edge, you may need to adjust the size of the shape by dragging its edges to ensure it covers the desired area.

By following these steps, you can effectively blur part of a photo in Paint by inserting a shape over the selected area and customizing its appearance to blend with the image.

Adjust the shape's colour and outline

To blur part of a photo in Paint, you can cover the desired part of the image with a shape. First, select a shape from the shape gallery that is suitable for covering the area you want to blur. Click and drag to draw the shape over the chosen area of the picture.

With the shape selected, you can adjust its colour and outline. To do this, select the 'Shape Format' tab on the ribbon and choose 『Shape Fill』 to select a colour for the shape. You can also change or remove the border of the shape by selecting 『Shape Outline』 and choosing 『No Outline』 or selecting a different border colour.

To blur the edges of the shape so that it blends better with the image, select 『Shape Effects』 and then 『Soft Edges』. After applying the soft edge, you may need to adjust the size of the shape by dragging one or more edges, as the shape may appear to shrink slightly.

This method can be used to blur specific parts of a photo in Paint by covering those areas with shapes and adjusting their colours and outlines to blend with the image.

Use the Soft Edges effect

To blur part of a photo in Paint, you can use the Soft Edges effect. This effect can be applied after covering a part of the photo with a shape. Here's a step-by-step guide on how to do it:

  • Open your photo in Paint.
  • Select "Insert" and then "Shapes" to insert a shape over the area you want to blur. Choose a shape that is suitable for covering the area you want to obscure.
  • Click and drag to draw the shape over the desired area.
  • With the shape selected, go to the "Shape Format" tab.
  • Select "Shape Fill" and choose a suitable color for the shape. You can match the color to the surrounding area of the photo to help the shape blend in.
  • To remove or change the border of the shape, select "Shape Outline" and then choose "No Outline" or select the desired border color.
  • Now, to blur the edges of the shape and create a softer transition with the rest of the image, select "Shape Effects" and then choose "Soft Edges".
  • Adjust the variation of the soft edge effect to achieve the desired blur intensity.
  • After applying the soft edge effect, you may notice that the shape appears slightly smaller. If needed, adjust the size of the shape by dragging one or more edges to cover the desired area.

By following these steps, you can use the Soft Edges effect in Paint to blur specific parts of your photo while blending the blurred area with the surrounding image. This technique can be useful for obscuring sensitive information, creating a depth-of-field effect, or adding creative blur effects to your photos.

Try alternative software like Paint.NET or sumopaint.com

If you're looking for alternative software to blur sections of a photo, Paint.NET offers a range of blur effects in its Effects menu. This includes the Sketch Blur, which creates an artistic effect akin to a coarse-grained brush stroke painting. The Radius settings in Sketch Blur let you control how much of the image is sampled, with lower settings creating the look of a smaller brush and higher settings mimicking a larger brush.

Another option in Paint.NET is the Bokeh Blur effect, which replicates the transformation of the Unfocus effect while allowing finer control through Radius, Gamma, and Quality adjustments. The Radius setting defines the strength of the blur effect, with higher settings resulting in more blurring. Adjusting the Gamma value can create a "high key" effect where lighter tones dominate, while lowering the gamma produces a "low key" effect that enhances darker tones and increases contrast. The Quality setting allows you to fine-tune the blurring by controlling its precision; higher values produce a better Bokeh effect but take longer to render, while lower values are faster but may result in a posterized appearance.

Sumopaint.com also offers a range of editing tools, including the ability to blur images. However, specific steps on how to achieve this effect were not readily available.
