Crop PDF

Quick answer: Crop PDF is a free online tool to crop PDF pages without uploading that lets you trim page margins right in your browser. Enter margins in points, click Crop PDF, and download — nothing is ever uploaded to a server.

Combine a scanned page with wide white borders, a slide with extra whitespace, or a document that needs a tighter frame, and cropping gives it a clean, professional look in seconds. Because everything runs client-side, your contracts, resumes, and private records stay exactly where they belong: with you.

What is Crop PDF?

Crop PDF without uploading means trimming the visible area of every page of a PDF right on your own computer or phone — no file ever travels to a server. You set how many points to remove from the left, top, right, and bottom of each page, and the tool sets a new CropBox for every page.

One point is 1/72 of an inch, so 36 points is half an inch and 72 points is one inch. A common choice is 36 points on all four sides to remove a half-inch border. If a page is uneven, use different values per side.

How to use Crop PDF

  1. Click the upload area and choose one PDF file.
  2. Enter the crop margins in points for left, top, right, and bottom. Enter at least one margin greater than zero.
  3. Click the “Crop PDF” button. Your browser trims every page locally.
  4. When processing finishes, the cropped file downloads automatically as a new PDF.
  5. Open the result to confirm the framing, then email, print, or archive it.

Crop PDF use cases

Removing scan borders

Scanned pages often carry dark edges or wide white borders. Cropping them away makes the document look clean without re-scanning.

Tightening slides and handouts

Slides exported to PDF with large margins waste screen space. A uniform crop makes them easier to read on a tablet or phone.

Preparing pages for printing

Trimming unwanted margins before printing avoids wasted paper and keeps the focus on the content itself.

Tips

  • Cropped content is hidden, not deleted. This tool is not redaction — do not use it to hide sensitive text that must never be recovered.
  • If margins are larger than a page, the tool will refuse the crop. Use smaller values and try again.
  • Start with 36 points on all sides and adjust from there; you can always re-crop the original, so keep it safe.
  • Very large PDFs can take a moment. If your browser struggles, crop in smaller batches.

Frequently asked questions

Is this PDF cropper really free?
Yes — completely free, with no account, no watermarks, and no page limits. Because cropping runs in your browser instead of on servers, there is no processing cost to pass on to you.
Do my files get uploaded to your servers?
No — your files are never uploaded to any server. They are read and cropped locally in your browser's memory and never travel over the internet.
Does cropping delete the cropped content?
No. Cropping sets a smaller visible area; the original content outside that area is hidden, not deleted. For true redaction, remove the sensitive content in the original document first.
What unit are the margins in?
Points. One point is 1/72 of an inch, so 36 points is half an inch and 72 points is one inch.
Does it work on my phone?
Yes — the tool runs in any modern mobile browser on Android and iPhone, with no app install required.
