How to Crop a Photo Using Paint.net. You can crop photos to remove unwanted items from the sides, top and bottom of a picture. Sometimes, it is easier to use other features on Paint.net once the photo has been cropped. Paint.net allows you to crop your picture using an ellipse or rectangle tool; here's how.
Step 1
Open Paint.net on your computer by clicking on the "Paint.net" desktop icon. You can also go through the program file to open the Paint.net program.

Step 2
Find the photo you want to crop. You can do this by clicking on the picture of the open folder located on the middle navigation bar.
Step 3
Access the tool selector menu on the third navigation bar. This will open a drop-down menu containing all of the tools available to use on the photo.
Step 4
Pick the "rectangle select" or "ellipse select" tool. The rectangle select tool allows you to crop your picture to a square or rectangle shape; the ellipse select tool allows you to crop your picture to a circle or oval shape.
Step 5
Move the cursor to the upper corner of the area that you want to remain. Hold the left mouse button down.
Step 6
Drag toward the bottom of the picture until the area you want to remain is completely in the dotted outline.
Step 7
Click on the "Image" button on the uppermost navigation bar. Select "Crop to Selection." This will crop the image to the area inside of the dotted outline.
Tip
If part of the picture you want to remain is out of the dotted outline, you may need to start over. To do this, simply release the mouse button and move your cursor to a new starting point.
