What is the simplest way to add a cover page to a PDF?

Make the cover as its own one-page PDF, then merge it in front of your document — the cover becomes page 1 and everything else shifts back by one. This works regardless of how the original was created, because merging just places the cover's page ahead of the rest. You can design the cover in any tool you like (a word processor, a design app, or from an HTML template) and export it to PDF, or use a ready cover and combine. The key is to produce the cover at the same page size as the document so it does not look mismatched when the two are joined.

How do I replace an existing cover page rather than add one?

Two steps: remove the current cover (page 1) from the document, then merge your new cover in front of the remaining pages. Always keep a backup of the original before removing anything, since deletion changes the file. If the old cover is more than one page (a cover plus a title page, say), remove the right range. After swapping, check that page numbering, any table of contents, and bookmarks still make sense, because removing and adding a front page can shift the relationship between printed and physical page numbers. The result is a document with your new cover and the original body intact.

Adding a cover broke my page numbers — what happened?

Adding a page at the front pushes every subsequent page back by one physical position, so what was physical page 1 is now page 2. If your document has printed page numbers baked into the content, those do not change automatically — only the physical position does — which can create a mismatch (the cover is "page 1" physically, but the body still says "1" on what is now physical page 2). This is usually fine and expected for a cover, since covers are conventionally unnumbered. If you need continuous numbering, add or redo the page numbers after assembling the final document rather than before.

Should the cover match the document's page size?

Yes — a cover at a different page size than the body looks broken when merged, with the cover either smaller (floating with margins) or larger (oversized) than the following pages. Before making the cover, check the document's page dimensions (Letter, A4, or something custom) and build the cover to match. If you already have a mismatched cover, resize it to the document's page size before merging. Consistent page size across the whole file is what makes a multi-source document — cover plus body plus maybe a back cover — read as one coherent document rather than stapled-together parts.

Can I make the cover from a template or HTML?

Yes, and it is a clean way to produce consistent covers. Design the cover as HTML (or a template document) and convert it to a PDF page, then merge it to the front. This is especially handy when you produce many documents that need the same branded cover with a few variable fields — title, date, author — since you change the template inputs and re-export rather than redesigning. Whatever route you use to create the cover, the assembly step is the same: produce a cover PDF at the right page size, then merge it ahead of the document.

How do I add covers to many documents consistently?

For a batch — rebranding a library of reports, say — standardise on one cover design at the documents' common page size, and apply it consistently: the same cover merged to the front of each file, named predictably. If covers carry per-document detail (a title), generate each cover from a template with that document's values, then merge. The discipline that keeps a batch clean is consistency: same page size, same design, same position (front), and a naming convention so you can tell updated files from originals. Keep the originals until you have verified the rebranded set.

Is it safe to do this with an online tool?

If the document is confidential, prefer a tool that processes files locally. ScoutMyTool merges, inserts, and removes pages entirely in your browser tab, so the document never leaves your machine while you add or change its cover. For anything you would not publish openly, confirm the tool does not upload before using it.

How to add or change a cover page on a PDF

By ScoutMyTool Editorial Team · Last updated: 2026-05-21

A good cover page does a surprising amount of work: it makes a report look finished, tells the reader what they are holding, and carries your branding before a word of content. I used to dread adding one, imagining I would have to rebuild the whole document — until I realised a cover is just a one-page PDF you merge to the front. That is the whole trick, and the same move in reverse (remove the old page 1, add a new one) swaps a cover out. This guide covers adding and changing PDF cover pages cleanly: making the cover at the right size, merging it to the front, replacing an existing one safely, and handling the page-numbering quirk that catches everyone the first time.

Cover-page tasks and how to do them

Task	How	Watch for
Add a cover to the front	Merge cover page + document	Page numbering now offset by one
Replace an existing cover	Remove old page 1, merge new cover	Keep a backup before removing
Add a blank/section cover	Insert a blank or divider page	Right position, double-sided printing
Cover from a template/HTML	Make cover as PDF, then merge	Match page size to the document
Back cover	Merge cover page at the end	Order in the merge list
Rebrand many docs	Swap covers in batch	Consistent size and naming

Step by step — add or replace a cover

Check the document’s page size. Letter, A4, or custom — your cover must match it, or the merged file will look mismatched.
Make the cover as a one-page PDF. Design it in any tool, or build it from an HTML template and convert with HTML to PDF at the matching page size.
Adding a cover? Merge it to the front. Combine the cover and the document with Merge PDF, cover first. (For a divider or blank cover, use Insert Blank Page.)
Replacing a cover? Remove the old page first. Back up the original, then drop page 1 with Remove Pages (see deleting pages) and merge the new cover in front.
Mind the page numbering. A front cover shifts physical pages back by one; covers are conventionally unnumbered, so this is usually fine. If you need continuous numbers, (re)apply them after assembling the final file.
Check bookmarks and TOC. If the document has an outline or contents page, confirm targets still land correctly after the front page changed.
Verify the result. Open the finished PDF, confirm the cover is page 1, sizes match, and the body is intact. For a polished look overall, see professional PDF tips.
