Add Margin to PDF
About this tool
Add Margin to PDF — Binding Margin for Printing
Add a binding margin to a PDF so nothing disappears under the hole punch or the binding. Everything runs locally in your browser — no upload, no sign-up, no watermark and no file size limit.
Left or Mirrored for Duplex
Add 5 to 20 mm on the left of every page, or mirror it for double-sided printing: odd pages get the margin on the left, even pages on the right, so it is always on the binding side.
Shrink the Content or Widen the Page
Keep the paper size and scale the content down just enough to make room, or keep the content at 100 % and make the page wider by the margin.
Nothing Turned Into Pictures
Text stays selectable, and links, form fields, comments and bookmarks move with the content, so the printed copy and the digital file stay the same document.
How to use it
- Drop the PDF you want to print and bind.
- Choose the margin width and whether to mirror it for double-sided printing.
- Choose whether to shrink the content or widen the page.
- Click Add margin and download the PDF.
Frequently asked questions
Are my PDFs uploaded to a server?
No. Toolula processes the document inside your browser tab with pdf-lib and WebAssembly, so the file never leaves your device.
Which side gets the margin with mirroring?
Pages 1, 3, 5 and so on get it on the left and pages 2, 4, 6 on the right, which is the binding side when the pages are printed double-sided and bound on the left.
Will the pages still fit my paper?
With Shrinking the content the page size stays the same, so it prints on the same paper. Widening the page makes each page wider by the margin, which suits printing with Fit to page.
Can I also change the page size?
Yes. Switch to Page size in the same tool to make every page A4, Letter or another size first.
Is it really free?
Yes. You can use every Toolula PDF tool for free, without an account. The free plan has fair-use limits; Toolula Pro, an optional plan, raises them and adds advanced features.
