Add Blank Page to PDF
Add Blank Page to PDF copies every source page and appends one empty page. Width and height default to 595×842 points—approximately A4—and zero or invalid values fall back to those defaults. One point is 1/72 inch in default PDF user space. The page has no margins, background art, header, or inherited template.

PDF page size is expressed in user-space points
The default coordinate system uses 72 points per inch. 595×842 pt approximates 210×297 mm A4.
How it works
The source pages are copied, addPage receives width and height, and the new PDF is downloaded.
Key concepts
Blank means no page content
It is not a copy of a template.
Dimensions use points
They are not pixels or millimetres.
When to use it
- Append a notes page.
- Add a simple spacer page.
- Create an empty page at custom dimensions.
When not to use it
- Do not expect insertion at an arbitrary position.
- Do not enter zero for a zero-size page.
- Do not expect source page styling or boxes to be copied.

Common mistakes
Entering millimetres
The fields use points. Correction: Convert mm to points.
Expecting middle insertion
The tool always appends. Correction: Reorder afterward.
Assuming a white rectangle is drawn
The page is empty; viewer background usually appears white. Correction: Add explicit content if required.
Best practices
- Choose a standard page size.
- Verify orientation and dimensions.
- Reorder if another insertion point is needed.
