Changing a photo resolution, or generally known as resizing is a way to reduce the overall pixels while maintaining the same content and aspect ratio. Furthermore, resizing can also lower the photo file size so it would be a perfect resolution for web or sending via email.
While there are a handful of photo editing programs both free and paid you can get, for a modification as simple as resizing, you can take the advantage of some first-party programs on your Windows device.
There are at least three programs that lets you perform resizing easily. Here are they.
