Your client wants the deliverable PDF to have your branded cover page in front. The deliverable itself doesn't have one — it's the raw report. You need to slap a cover on the front.
Merge with cover-first ordering. Flint does it in two drops.
Use merge, cover first
Open merge PDF, drag your cover PDF first, then drag the report. Order matters — cover comes first means cover becomes page 1. Click merge. The output is your cover followed by the report. Done.
Don't have a cover PDF yet?
Create one in Word/Pages/Docs, export to PDF, then merge with the report. Or use edit PDF to insert a blank page and add your title text/logo manually. Either path; pick whichever is faster for your workflow.
Multi-page cover (title + contents + intro)
Same flow. Your cover file can be multiple pages. Drop it first in merge PDF, drop the body after. The output puts all your cover pages first, then the body.
Replacing an existing cover
If the report already has a cover you want to replace: delete the existing cover first, then merge with your new cover in front. Two operations: delete, then merge. Or do it in one: merge new cover + body, then delete the duplicate cover page from the result.
FAQ
Will internal links break when adding a cover?
Links pointing at body pages remap to new positions. The body's internal navigation continues to work.
Does the cover affect page numbering of the body?
Body pages shift by the cover's length. Page labels move with their pages. Use edit PDF to relabel if needed.
Can the cover have a different page size?
Yes. Letter cover + A4 body merges fine. Each page keeps its size.
Do bookmarks update?
Yes. Bookmarks remap to new positions automatically.
Drag cover, drag body, merge. Add a cover page.
