How to Crop a PDF

Step 1: Upload Your PDF

Drag your PDF onto the page or upload it from your computer or Dropbox.

Step 2: Choose a Crop Method

Auto Crop automatically trims unnecessary white space. Fixed Margins, Percentage, and Custom Rectangle let you define the crop area yourself. Each method is explained in detail below.

Step 3: Select the Pages

Choose all pages, enter specific page numbers such as 1, 3, 5, or select a continuous range such as 1-5.

Step 4: Crop and Download

Click Crop PDF to apply your settings. Check the result using View, then download your cropped PDF.

The Four Crop Methods

Choose from four ways to crop your PDF, depending on the document and the area you want to keep. You can automatically remove empty space or define exactly how much of each page should remain.

Auto

Auto Crop detects the content on each page and trims the empty space around it. It is best for scanned documents with uneven borders and PDFs created from photos.

Check the result before downloading, as faint marks near the page edges may be detected as content and affect how much space is removed.

Fixed Margins

Remove a specific amount from the Top, Bottom, Left, and Right edges of each selected page. This method is useful when pages have consistently wide margins, such as a book that has been scanned flat.

Set the crop amount for each side to remove unwanted borders while keeping the remaining page area consistent.

Percentage

Crop each side by entering a percentage of the page dimensions rather than a fixed measurement. This is useful when your PDF contains pages of different sizes and you want to remove the same proportion from each selected side.

Set the percentage for the Top, Bottom, Left, and Right sides according to how much of the page you want to remove.

Custom Rectangle

Define exactly which rectangular area of a page you want to keep by entering four values: X, Y, Width, and Height. X and Y determine where the selected area starts, while Width and Height determine its dimensions.

Use this method to isolate a shipping label, chart, table, or individual receipt from a larger page.

Other Settings

In addition to choosing a crop method, you can adjust these settings to control how the crop is applied and what information is retained:

  • Unit: Choose Points, Inches, Millimetres (mm), or Percentage when entering crop measurements. 72 points equal one inch.
  • Pages: Apply cropping to all pages, selected pages using a list such as 1,3,5, or a continuous range such as 1-5.
  • Auto Detect Whitespace: Set this option to True to let the tool detect and trim unnecessary white space in addition to your chosen crop method.
  • Preserve Metadata: Keep document information such as the author and creation date, or remove embedded metadata before sharing the cropped PDF.

Common Reasons to Crop a PDF

Cropping a PDF helps remove unwanted borders, adjust page dimensions, and keep only the content you need. Here are some common situations where the different crop methods can help.

Printing a Shipping Label on a 4x6 Label Printer

Couriers and online marketplaces often provide shipping labels as A4 PDFs, with the actual label in one corner and instructions covering the remaining space. Use Custom Rectangle to keep only the label area, then print the cropped PDF on your 4x6 thermal label printer.

Removing Black Borders from Scanned Pages

Phone scans and photocopies can contain dark edges, shadows, or unwanted borders around the document. Use Auto Crop to detect the page content and remove surrounding empty space so the pages look cleaner when viewed, printed, or shared.

Reducing Wide Margins for Reading on a Phone or Tablet

Academic papers and ebooks sometimes have large margins that leave less room for text on smaller screens. Use Fixed Margins to trim the unnecessary space around the pages and make the content easier to view on your phone or tablet.

Removing Headers or Footers Before Printing

Some PDFs contain unwanted website headers, page URLs, or print dates along the edges. Use Fixed Margins to remove a small amount from the top or bottom of each selected page before printing.

Is It Safe to Crop PDFs Online?

Your PDF is transferred to our servers over an SSL-encrypted connection and automatically deleted 1 hour after upload. Nobody at ILOVEPDF.BIZ opens your uploaded documents.

Keep in mind that cropping hides the trimmed area but does not necessarily remove the underlying content. If you need to permanently hide confidential information, use Redact PDF instead, which removes the selected content.

Crop PDF FAQs

What does cropping a PDF do?

It trims the visible edges of a page, such as margins, white space, or a header, while keeping the rest of the content. To change the page size itself, for example to A4, use Resize PDF.

Will cropping affect PDF quality?

No. Text and images inside the crop area stay exactly as they were.

Is it possible to crop only some pages?

Yes, you can crop all pages, selected pages, or specific page ranges.

Can auto crop cut off part of my content?

Auto Crop trims around the content it detects, so text and images are normally kept. Faint marks near the edge can be treated as content, so check the result using View before downloading.

Can I use custom measurements?

Yes. Choose points, inches, millimetres, or percentage in the Unit setting.

How long are my files stored?

One hour. After that, your original and cropped PDFs are automatically deleted from our servers.

Does cropping change metadata?

Only if you choose to. Set Preserve Metadata to False to remove the author, creation date, and other document properties.

Is Crop PDF Online free to use?

Yes. It's free with no sign-up required and no limit on the number of files you can process.

Does cropping permanently delete the trimmed area?

No. Cropping changes the visible area of the page. The trimmed content is hidden, not deleted, and may still exist in the underlying file. If you need to permanently remove sensitive content, use Redact PDF instead.

Will cropping reduce my file size?

Not on its own. Cropping changes what is visible, not necessarily the underlying file size. If you also need a smaller file, use Compress PDF afterward.

Why are my scanned pages cropping unevenly?

Scanned pages are sometimes slightly rotated, which can affect Auto Crop detection. Use Rotate PDF to straighten the pages first, then crop them again.

How do I crop a shipping label from a PDF?

Choose Custom Rectangle and set Unit to Millimetres. Enter the X and Y coordinates where the label starts, along with its Width and Height. Type All in Pages to apply the same crop area to every page in the PDF.
