What is the Add Margins to PDF?

Some documents come with no room to breathe: text runs to within a few millimetres of the edge, which is a problem if you need to punch holes, bind the document, write notes in the margin, or print on a machine that cannot print to the edge of the paper.

  • Two modes: grow the page, or shrink the content to fit
  • Margins in millimetres, inches or points
  • Independent control of all four sides, or one value for all
  • Correct handling of pages that carry a rotation
  • Grow mode is lossless — text stays selectable and sharp
  • Runs in your browser with no upload

About the Add Margins to PDF

Some documents come with no room to breathe: text runs to within a few millimetres of the edge, which is a problem if you need to punch holes, bind the document, write notes in the margin, or print on a machine that cannot print to the edge of the paper.

This tool adds that space in either of the two ways that make sense. Growing the page keeps your artwork at exactly its original size and makes the sheet bigger around it, which is right when you are printing on larger paper. Keeping the page size instead shrinks the content slightly and centres it, which is right when the paper size is fixed and you just need a wider margin.

Margins can be set in millimetres, inches or points, individually or locked together, so you can give the binding edge more room than the other three. Pages that carry a rotation are handled properly, meaning the margins land on the edges you actually see rather than the raw ones. Everything runs locally with pdf-lib and nothing is uploaded.

Frequently asked questions

Should I grow the page or shrink the content?

Grow the page when you can print on a larger sheet, because your artwork stays at full size and full quality. Shrink the content when the paper size is fixed and you need the margin to come from somewhere.

How much margin do I need for binding?

For a hole-punched or comb-bound document, around 20 mm on the binding edge is usually comfortable. Untick the linked option and set just the left margin wider than the other three.

Does adding margins reduce quality?

In grow mode, no — the page box is enlarged and nothing is re-rendered, so text stays selectable and images keep their resolution. In shrink mode the content is scaled down slightly but still stored as vectors, so it stays sharp.

Will this change my page size for printing?

In grow mode, yes — an A4 page with 15 mm margins all round becomes about 625 by 872 mm across, so tell your print dialog not to scale it. In shrink mode the page size is unchanged.

Can I add a margin to only one side?

Yes. Untick the option that keeps all four margins the same, then set the sides you want and leave the others at zero.
