PDF Margin Adjuster

How to Add or Remove PDF Margins

1. Drop your PDF onto the upload area, or click Browse PDF.
2. Enter the margins. Fill in Top Margin, Bottom Margin, Left Margin and Right Margin in points. One point is 1/72 inch, and all four boxes start at 36, about half an inch.
3. Or click a preset: Standard (0.5"), Wide (1"), Narrow (0.25"), No Margins or Crop 0.5". A positive number adds white space. A negative number crops that much off the edge.
4. Check the preview. Preview (First Page) shows your page inside the new sheet, and the cards above it compare the Original Size with the New Size. Click Preview Changes to refresh it, or Reset to Zero to start again.
5. Click Apply Margins & Download. The same values are applied to every page, and the numbers are added to the file name, for example _margins_36_36_36_36.pdf.

Why Use This PDF Margin Tool

• Your file stays on your device. The pages are rebuilt by code running in your browser. Nothing is sent to a server.
• A separate value for each side. Add extra room on the left for binding, or on the right for handwritten notes.
• Add or crop in one tool. Positive values grow the sheet. Negative values, down to -200 points, trim the edges.
• See it before you save. The preview shows the first page with your margins marked, and the new page size is listed in points.

Good to know: pages are placed on the new sheet as they are, so text stays selectable and searchable. Pages that are rotated, or whose visible area differs from the full page, are redrawn as images instead, and those pages lose their selectable text. Links do not carry over. The content is not scaled. Adding margins makes the page bigger instead of shrinking what is on it, so a Letter page with 36-point margins becomes 684 by 864 points. Cropped areas are hidden, not erased, because the full page is still inside the file. Do not use cropping to remove sensitive content. Use Redact PDF for that, or Crop PDF if you would rather draw the crop area yourself.

FAQ

How do I add margins to a PDF?

Drop your PDF onto the tool, type a positive number of points in each of the four margin boxes, check the preview and click Apply Margins and Download. Every page gets the same margins.

How do I remove or crop margins from a PDF?

Enter negative values. Crop 0.5" in the preset list uses -36 points on each side. Each page becomes smaller by the amount you remove, and whatever sits outside the new edge is hidden.

What unit are the margins in, and how big is a point?

Points. One point is 1/72 inch. So 36 points is half an inch (12.7 mm), and 72 points is one inch (25.4 mm).

Does the tool shrink my content to fit the margins?

No. The original page is placed on a new sheet that is larger by the margin amount. If you need a fixed paper size such as A4, run the result through Resize PDF.

Will the text in my PDF still be selectable?

Yes, for most pages. The original page is placed on the new sheet, so its text stays selectable and the file stays close to its original size. Rotated pages, and pages whose visible area differs from the full page, are redrawn as images at about 144 DPI, so they lose selectable text.

Is my PDF uploaded anywhere, and is there a size limit?

No, the PDF stays on your device while it is processed in your browser. Your file size limit is shown on this page, and a free account raises it.
