You can open a Paint.NET file, or any other compatible image file, using the standard file opening methods within the program. This typically involves using the Open File dialog.
The primary way to open an existing image file, including Paint.NET's native .pdn format or other common types like .jpg, .png, or .gif, is through the program's Open File dialog.
Here's how:
- Using the Menu: Go to the File menu and select Open....
- Using the Keyboard Shortcut: Press Ctrl + O on your keyboard.
Both actions will bring up the standard Open File dialog box for your operating system. From here, you can navigate through your computer's folders to find the file you wish to open. Select the file and click the Open button.
Opening Specific File Types
Paint.NET supports a wide range of image file formats. When using the Open File dialog, you can often filter the displayed files by selecting a specific file type from the "Files of type" dropdown menu, or simply leave it on "All Files" if you know the location.
Paint.NET's native format, .PDN (Paint.NET Image), is important because it preserves layers, history, and other editing information. Opening a .PDN file lets you continue editing exactly where you left off.
Opening Files from a URL
Interestingly, Paint.NET also allows you to open an image file directly from a web address or URL using the same Open File dialog. This can be handy if you have the direct link to an image online and want to edit it quickly without manually downloading it first.
Here are the steps, incorporating information from our reference:
Steps to Open from a URL
- Access the Open File dialog. You can do this by pressing Ctrl + O or by going to the File menu and selecting Open....
- In the Open File dialog window, find the File Name text box at the bottom.
- Click in the File Name text box and paste the copied URL (using the keyboard shortcut Ctrl + V or right-clicking and selecting Paste).
- Then click Open.
Paint.NET will then attempt to download the image from the provided URL and open it within the program.
Supported Image Formats
Paint.NET can open numerous popular image formats. While not exhaustive, here are some of the most common ones:
- .PDN (Paint.NET Image - supports layers)
- .JPG / .JPEG (Joint Photographic Experts Group)

Table of Common Supported Formats

By using the standard File > Open menu or the Ctrl + O shortcut, you can easily access and work with your image files in Paint.NET, whether they are stored locally or available via a URL.
