How to crop a PDF

  1. Upload the PDF. The first page appears in the preview area so you can see what you are trimming.
  2. Enter crop values in PDF points for each edge — top, bottom, left, right. 72 points = 1 inch = 2.54 cm. For a typical A4 with 2 cm white margins, values around 56 on each side work well.
  3. Click Crop PDF. The same crop is applied to every page using the PDF's MediaBox — no pixels are re-rendered, so quality and file size stay the same.

When cropping helps

Frequently asked

Is the cropped content permanently deleted?

No — cropping in PDF only hides the region outside the MediaBox. Someone can uncrop the file in another editor. If you actually need to destroy the content, use Flatten or Redact after cropping.

Why are dimensions in points, not cm or inches?

PDF's native unit is points. We surface them directly so you can match exact values from a design spec. For everyday use, just experiment — the preview updates live.

Can I crop different pages differently?

Not in this tool — one crop is applied to all pages. For per-page cropping, split the document, crop each piece, then merge back.

Does cropping reduce file size?

No. Hidden content is still inside the file. For smaller output, run Compress PDF after cropping.

Privacy: Cropping runs locally with pdf-lib — only MediaBox values change, never the page streams. Your PDF is not uploaded.
