Remove Unwanted Margins and Borders from PDFs

Scanned PDF with huge margins? Borders taking up too much space? MyPDF's Crop PDF tool trims page margins and adjusts the visible area of your PDF pages.

How to Crop a PDF

Step 1: Upload Your PDF

Open the Crop PDF tool and upload the document you want to trim.

Step 2: Set Crop Margins

Choose your cropping method:


  • Visual crop — Drag a rectangle on the page preview to define the visible area

  • Margin values — Enter exact top, bottom, left, right margins to remove (in mm or inches)

  • Auto-crop — Automatically detect and remove white borders


Step 3: Apply to Pages

Choose to apply the crop to:


  • All pages

  • Even pages only / Odd pages only

  • Specific page ranges


Step 4: Download

Download the cropped PDF with trimmed margins.

Common Use Cases

  • Remove scanner borders — Scanners often add black or white borders
  • Trim lecture slides — Remove excessive margins for better screen reading
  • Resize for print — Adjust margins to fit a different paper size
  • Remove watermarks — If a watermark is only in margins, crop it out
  • Fit to screen — Remove margins so content fills the screen on e-readers

Tips

  1. Auto-crop for scans — Automatically removes black scanner borders
  2. Different margins per side — Set different values for top, bottom, left, right
  3. Compress after cropping — Use Compress PDF since cropping doesn't reduce file size (it hides content, doesn't delete it)
  4. Rotate first — Use Rotate PDF if pages are sideways before cropping

Frequently Asked Questions

Does cropping reduce file size?

Not significantly. Cropping changes the visible area but the original content remains in the file. Use Compress PDF to actually reduce size.

Can I crop different pages differently?

Yes. Apply different crop settings to even vs. odd pages, or specific page ranges.

Is it free?

100% free — no sign-up, no watermarks.
