Crop PDF Margins

A PDF covered in wide white borders looks unfinished and wastes space on every screen and page of print. The crop tool trims each side of every page by the exact amount you specify, in points or millimeters, so you can remove excess margins in seconds. Everything happens locally in your browser with nothing uploaded anywhere.

What Cropping Actually Changes

Cropping adjusts the visible boundary of each page rather than deleting your content. The tool rewrites the page crop box, pulling it inward by the values you enter for the top, bottom, left, and right edges. Text, links, and form fields inside the new area remain fully intact, and everything outside the boundary is hidden from view.

Because the original content is not destroyed, the crop is essentially non-destructive. If you kept a copy of the source file you can always return to it, and the trimmed result keeps the structure of the original document intact.

Cropping is also not resizing. It never scales your content to fit a new page size, and it does not rotate the document. The crop is a pure trim: the remaining text keeps its exact size and position, which is what makes the tool ideal for cleaning up scans and exports without altering the layout.

Points or Millimeters

You can enter values in either unit. Points are the native unit of PDF documents, where an inch equals 72 points, and millimeters are convenient when you are working from a physical ruler or a print layout. Just switch the unit before typing your numbers; the tool converts everything consistently when it applies the crop.

Why Documents Gather Unwanted Margins

Unused borders usually come from how a file was made. Scanners capture the white paper around a page, presentation tools export slides with generous padding, and print-oriented layouts build in margins meant for paper rather than screens. None of that whitespace helps when you are reading on a monitor or submitting a clean digital file, and all of it shrinks the space your actual content occupies.

Even small amounts of trimming help. Removing a quarter inch of white from a border-heavy layout can reclaim a surprising amount of readable area across a long document.

How to Crop a PDF

1. Upload your PDF by clicking the upload area or dragging the file onto it.
2. Enter the amount to trim from the top, bottom, left, and right. You can use 0 for any side you want to leave alone.
3. Choose between points and millimeters, then click Crop PDF.
4. Check the before-and-after preview and download the trimmed file.

When You Will Notice the Difference

The clearest payoff shows up on scanned documents, where a border of paper surrounds every page. Cropping those edges makes text larger on screen, uses paper more sensibly when you print, and removes the distracting frame from presentations. A presentation exported from slides is another obvious case: a uniform trim across the deck makes it look designed rather than default.

Free, Fast, and Private

Free users can crop PDFs up to 10 MB with a short processing wait, and Premium subscribers enjoy larger files with no wait. Because the crop is applied client-side, your document never touches a server, which makes it safe for contracts, forms, and anything else you would rather keep on your own machine.

There is no signup and no watermark on the output. Upload a file, set your margins, and the finished PDF downloads with a cropped- prefix so you always know which version you are looking at.

• Trims each of the four sides independently, so uneven borders are easy to fix.
• Applies the same margins to every page in one pass.
• Keeps text selectable and searchable after the crop.
• Preserves links and form fields that fall inside the new area.
• Shrinks the effective canvas, which can make the file lighter before compression.
• Works in points or millimeters depending on what you are comfortable with.
