Map the final document first
Write down the intended order: cover letter, form, evidence, appendix, for example. Rename source files clearly before combining them so similar scans are not confused.
If two PDFs have their own cover sheets or blank trailing pages, decide whether those pages belong in the result.
Combine without destroying sources
- 1
Select the source PDFs
Use the correct versions and keep originals untouched.
- 2
Arrange the files
Place them in the final reading order.
- 3
Create the merged copy
Use a new descriptive file name.
- 4
Inspect every boundary
Check the last page of one source and first page of the next.
Common merge mistakes
- Old and new versions of the same form both included
- A signed page placed before the form it belongs to
- Blank scanner pages between attachments
- Different page rotations or sizes
- Searchable text lost during unnecessary conversion to images
Verify for the destination
Open the merged PDF, confirm the page count, search for a phrase if it should remain searchable, and check the file size. A submission portal may impose both size and page limits.
If the file is too large, compress a copy after merging so you can evaluate the complete output once.
