About this tool
A border printed around every page gives a document a finished, deliberate look — the kind of touch used on certificates, formal reports, invitations and print-ready booklets. Doing it by hand in a page-layout tool means re-drawing a rectangle on every single page and hoping the margins line up; this tool draws it once and applies it consistently across the whole document in one pass. Drop in a PDF, pick a color, a stroke width and a margin from the edge, and choose a single ruled line or a classic double-line frame.
Everything is measured in points (1/72 of an inch, the unit PDF page geometry is built on), and the border is drawn as an outline only — your existing page content is left completely untouched underneath it, nothing is covered up or clipped. Because the frame sits inside the margin you choose, very small pages paired with a large margin or a thick line can leave no room for a rectangle at all; this tool catches that case up front and tells you exactly which page size is too tight, instead of silently producing a broken PDF.
Frequently asked questions
Will the border cover up content near the page edges?
The border is drawn as an unfilled outline (a stroke only, no fill), so it never covers or blocks out existing content underneath — but if your document already has content very close to where the border line will sit, the two may visually overlap. Increase the margin setting to push the border further from the edge if your content extends close to it.
Can I use a different border color for different pages?
Not in a single pass — this tool applies one chosen color, width, margin and style uniformly to every page in the file. To get different borders on different pages, split the PDF into separate files first (with the PDF Split tool), apply a border to each with different settings, then merge them back together (with the PDF Merge tool).
