Can I delete all photos from iphone from Windows 11?

An old iPhone 15 Pro Max and there are approximately 5000 photos on it. Now, I already have all photos backed up to an external hard drive. Is there a simple way to allow me deleting all photos from iphone. I don't want to select the photos one by one. I heard it is possible to get this done on a Windows computer as there are dedicated iphone erasing app out there. Is this true?
