How to Blur the Whole Image in PowerPoint

If you don’t want to install a third-party tool, Microsoft PowerPoint allows you to blur a picture directly. Different from WorkinTool Image Converter, PowerPoint is not that straightforward and only allows you to blur out a picture entirely. Although it is feasible to blur a part of a picture, it is too time-consuming and laborious. You need to make more manipulation of the other tools like inserting shapes. But creating an entirely-blurred picture is a breeze in it.

Here is how to blur the whole image in PowerPoint.

  • Step 1: Create a new presentation and insert a picture in Microsoft PowerPoint.
  • Step 2: Click on the picture, then navigate to the Picture Format

How to Blur the Background of a Picture on iPhone

Another practical way solves your problem from the beginning. Your picture background can be blurred when you are shooting a photo. It is also available to adjust the blur gradient after shooting. To achieve that, we need to use the built-in Camera app on iPhone. With the Portrait mode, we can make the background of a picture blurry in a few clicks. The blur intensity is decided by the f value. The higher the f value, the lower the blur level. When we take a picture, it is better to set the f value as 2.8, which can give you a natural bokeh effect.

Here is how to blur the background of a picture using the Portrait mode in Camera.

  • Step 1: Open the Camera on your iPhone and switch to Portrait
