Choose the right position
The reference is a page in the loaded document, not a future position. To add a sheet at the beginning, select 1 and insert before. At the end of a 12-page PDF, select 12 and insert after.
If chapters end at 3,7,11, select these references and insert after. Insertions do not replace any original sheet.
Dimensions and quantity
Each blank sheet matches its reference’s dimensions and orientation. A PDF mixing A4, Letter and landscape appendices can produce differently sized blank sheets; this is intentional.
- Load the PDF and check its total.
- Enter reference numbers or ranges, such as 1,4,8-10.
- Choose before or after and 1 to 10 sheets per reference.
- Download and inspect positions, dimensions and total in your viewer’s thumbnails.
Limits and differences
Insertion creates empty sheets; duplication repeats existing contents. Grids, ruled lines, form fields and numbers are not added.
Repeated references count as one position. Outputs support up to 500 pages. Printed numbers are not updated: number the final document after insertion. The original remains intact and processing is local.
