How to Crop a PDF Free (2026 Guide)
Trim scanner margins, cut white space, or resize every page to a standard size — free, no signup, no watermark, right in your browser.
Method 1: PDFCourt (100% Free Online)
RECOMMENDED✓ Best for: scanned documents with dark borders, or standardizing page size across a document set
Why it's #1: free, no signup, and shows a live shaded preview of exactly what gets trimmed before you download anything.
Step-by-Step Instructions:
Open PDFCourt and upload your PDF
Visit PDFCourt.com/crop-resize and drop in your file. No download or installation required.
Set a margin to crop, in millimeters
Enter a top/bottom/left/right margin — the same amount trims from every page. The preview updates live with a shaded overlay showing what gets removed.
Optionally resize to a standard size too
Pick A4, Letter, Legal, or a custom size — content scales proportionally and stays centered, so nothing gets stretched. Landscape pages stay landscape automatically.
Download your cropped PDF
Click "Crop & Resize" and download instantly — applied to every page in one pass.
Method 2: Adobe Acrobat DC (Paid Software)
Cost: $19.99/month or ~$240/year
Best for: organizations already paying for Adobe. Not worth subscribing just to crop a PDF.
Steps:
- Open Adobe Acrobat DC (not the free Reader)
- Go to Tools → Organize Pages → Crop
- Drag the crop box on the page, choose which pages to apply it to
- Click Apply
Note: the free Acrobat Reader cannot crop pages. You need the paid DC version, and dragging a crop box precisely by eye is harder to get consistent across every page than entering an exact millimeter margin.
Crop vs. Resize — which do you need?
Crop
Trims margins from the existing page — the page gets smaller, nothing scales. Use this to remove a scanner's black border or excess white space.
Resize
Scales the whole page onto a new standard size like A4 or Letter — content shrinks or grows proportionally and stays centered. Use this to standardize page size across a document assembled from multiple sources.
You can do both in the same pass — set a crop margin and pick a target size, and PDFCourt trims first, then resizes what's left onto the new page.

Frequently Asked Questions
What's the difference between crop and resize?
Crop trims margins from the existing page (e.g. removing a scanner's border) without changing the underlying page size. Resize scales the whole page onto a new size like A4 or Letter. You can do either one, or both in the same pass.
Does resizing distort my content?
No — content is scaled proportionally to fit the new page size and centered, so nothing gets stretched or squashed.
What happens to landscape pages if I resize to A4?
Landscape pages stay landscape — PDFCourt automatically uses the landscape version of whatever size you pick, so orientation is preserved per page.
Can I crop and resize every page at once?
Yes — both crop and resize apply to every page in the document in a single operation.
Do I need Adobe to crop a PDF?
No — PDFCourt crops and resizes directly in your browser, free, with no Adobe Acrobat or other software required.
