Screenshots and images downloaded from the web are usually saved as JPG or PNG files. Sometimes, you might need to convert these files to PDF format. Here's how to do that in Windows 10 with the built-in Photos app.

The default photo-viewer app in Windows 10 is Photos. When you double-click an image, it should open in the Photos app. If you haven't changed the default app to view photos, locate and double-click the JPG file that you want to convert to a PDF to open it in Photos.
