📄 Add Header and Footer to PDF

About Header/Footer

Long reports, manuals and contracts need a running head so readers know where they are and who issued the document. This tool lays down the same text on every page, in the margin you choose, at the point size you set. Because it is native PDF text, the header remains selectable and prints sharply even after many generations of photocopying, and the original page content is left completely untouched underneath.

Running Heads as Document Infrastructure

Any document longer than a handful of pages starts to lose its identity the moment individual pages leave the whole. A PDF that travels through email threads, gets printed for a meeting, or has three pages excerpted into a presentation needs a quiet, persistent signal on every page that says what it is and who issued it. That is the job of a running header or footer. It is the document equivalent of a letterhead that does not shout: the title, the chapter, the revision date or a simple page number, repeated in the margin so no page is ever an orphan.

The reason to apply this to a finished PDF rather than rebuilding the source is the same reason you would not repaint an entire wall to hang one picture. If the body of the document is already final (approved, exported, maybe even signed) the running head is an addition, not a redesign. Applying it page by page through a layout program invites accidental shifts in margins, fonts and spacing. Doing it as a controlled overlay on the existing file keeps every original page pixel-for-pixel identical while adding the structural text the document was missing.

Matching the Document, Not Fighting It

A running head that clashes with the existing typography looks worse than no running head at all. The tool lets you set the text, the size and the margin placement so the addition can blend with the document rather than announce itself. A long report with an 11-point body usually wants a header at 9 or 10 points in the same typeface family, sitting far enough from the body text that the eye reads them as separate layers. A legal contract might want a smaller, all-caps footer carrying nothing more than a confidentiality line and a page reference. In both cases the goal is the same: the running head should feel like it was always there.

Independent header and footer control matters because the two often carry different jobs. The header typically answers “what am I reading?” (a document title, a chapter name, a project code. The footer typically answers “where am I and who owns this?”) a page number, an issue date, a company name. Treating them as separate fields rather than forcing one string into both positions lets each margin do the work it is conventionally expected to do, which is what a reader familiar with professional documents will subconsciously look for.

Native Text and Document Integrity

Drawing the running head as native PDF text rather than an image overlay preserves two properties that matter in real workflows. First, the text stays selectable and searchable, so a reader who highlights a passage and copies it, or a system that indexes the file for full-text search, treats the running head exactly like any other text in the document. Second, it stays sharp through unlimited zoom and through generations of photocopying, the classic test of whether a document has been assembled carefully or hastily. An image-based header blurs after two photocopy cycles; a vector one does not.

Underneath all of this, the original page content is left completely untouched. The tool adds the running head as new objects in the margin rather than reprocessing or reflowing the body, which means embedded fonts, images, form fields and existing annotations all survive exactly as they were. For documents that must retain evidentiary or archival integrity, that non-destructive property is not a convenience, it is a requirement. The addition is visible, the original is intact, and the two coexist without either one compromising the other.
