How to Crop PDF Online Free — 4 Methods (2026)

Why Crop a PDF?

PDFs often come with excess white space — wide margins from scanning, blank edges from conversion, or unwanted header/footer areas. Cropping removes the dead space to:

* Save space — cropped PDFs are smaller and easier to read on mobile * Improve readability — content fills the screen on tablets and ebook readers * Prepare for print — trim marks and bleed areas need precise cropping * Extract regions — pull specific diagrams, charts, or sections from large documents

Method 1: ExactPDF Crop Tool (Fastest — 10 Seconds)

Open Crop PDF in your browser

Drop your PDF into the upload area

Drag the crop handles to set your area — or enter exact dimensions

Choose whether to apply the crop to one page or all pages

Click "Crop" and download your trimmed PDF

Why this is best: Runs entirely in your browser. Your file never leaves your device — no upload, no account, no daily limits.

Method 2: Mac Preview (Built-In)

Open the PDF in Preview

Click the Markup toolbar button

Drag to select the area you want to keep

Go to Tools → Crop (Cmd+K)

Save the file

Limitation: Preview crops the *view* but doesn't always remove the hidden content permanently. The cropped areas may still be recoverable.

Method 3: Adobe Acrobat (Paid)

Open the PDF in Acrobat Pro

Go to Edit → Edit PDF → Crop Pages

Set precise margins in the dialog

Apply to selected pages or all pages

Limitation: Requires an Acrobat Pro subscription ($22.99/month). The free Reader version cannot crop.

Method 4: Google Chrome Print-to-PDF

Open the PDF in Chrome

Press Ctrl+P (Cmd+P on Mac)

Set destination to "Save as PDF"

Adjust the scale and margins

Save

Limitation: Imprecise — you can't set exact crop dimensions. Works as a quick workaround when no other tool is available.

Tips for Better PDF Cropping

* Remove white margins uniformly: Apply the same crop to all pages for a consistent look * Check dimensions first: Know your target size (A4, Letter, custom) before cropping * Crop before compressing: Cropping first removes unnecessary image data, making compression more effective * Back up the original: Cropping is destructive — keep a copy of the original file

Frequently Asked Questions

Does cropping reduce PDF file size?

Yes. Cropping removes the trimmed content which can significantly reduce file size — especially for scanned documents with large white borders.

Can I crop a specific page without affecting others?

Yes. ExactPDF lets you select individual pages to crop while leaving the rest unchanged.

Is cropping the same as resizing?

No. Cropping removes content from the edges. Resizing scales the entire page to different dimensions while keeping all content.
