Add Margins to PDF
Add extra white space around every PDF page for binding, notes, or printing in seconds. Free, no signup, no uploads — it works in your browser.
Everything runs inside your browser — your file is never uploaded to a server.
About this tool
This tool pads every page of a PDF with extra blank space on all sides, which is exactly what you need before spiral-binding a document, hole-punching a report, or leaving room for handwritten notes in the margins. Set the margin size in points and choose whether the page should keep its original dimensions — shrinking the existing content to fit inside the new border — or grow larger to add pure white space around content that stays full size. Because the tool works with pdf-lib entirely in your browser, adding margins to a signed legal document or a client proposal never means sending it to a third-party server first. The layout, fonts and images inside each page are preserved exactly; only the surrounding space changes, so the document still looks and reads the same, just with breathing room for a binder, hole punch, or printer's trim.

Why use this tool
Documents prepared for on-screen reading rarely leave enough room for a hole punch, a spiral binding coil, or a reviewer's handwritten comments in the margin. This tool adds that missing space to every page at once instead of forcing you to manually resize content in a design program, making a report or manuscript ready for physical binding or annotation in a single pass.
Tips & best practices
- Use a margin of at least 36pt (half an inch) if the document will be hole-punched or comb-bound.
- Keep the original page size when you need the final printed dimensions to match a specific paper size like Letter or A4.
- Add a larger margin on one side only by combining this with a separate crop step if you need asymmetric binding space.
Common use cases
- Preparing a report for spiral binding by adding space along the edge that will be punched.
- Leaving room for handwritten feedback in the margins of a draft manuscript.
- Adding a printer-safe border to a document before sending it to a commercial print shop.
- Padding a scanned worksheet so it can be hole-punched into a school binder.
- Framing slide exports with white space before compiling them into a printed handout.
Frequently asked questions
What unit is the margin measured in?
Margins are set in points, where 72 points equal one inch, giving you precise control over the added space.
Will my content shrink if I keep the original page size?
Yes, with that option enabled the existing content is scaled down proportionally so it fits inside the new margin on an unchanged page size.
What happens if I don't keep the original size?
The page itself grows larger by the margin amount on each side while your original content stays at its original scale in the center.
Is this useful before printing?
Yes, adding margins is a common step before spiral or comb binding, hole-punching, or leaving space for a printer's non-printable border.
Does it work on scanned PDFs too?
Yes, it works on any PDF page regardless of whether it contains scanned images, native text, or a mix of both.
