The built-in Microsoft Print to PDF application can combine multiple pictures into one multipage PDF file:
- Select the pictures in File Explorer,
- Right-click any of them,
- Select Print from the context menu.
- Select 'Microsoft Print to PDF' from the printer dropdown.
- Select the desired options.
This does not work for arbitrary documents though; you do need a third-party utility for that.
