▪Default Zoom
| This is the zoom level at which a document is displayed when it is opened. This does not change the PDF in any way, as this setting is global and and is not saved in the individual PDF file. |

| If this option is enabled, PDF Pro will ignore the initial zoom stored in the PDF file and use the default zoom selected above. |
▪Initial View / Initial Zoom / Initial Page
