Crop Pages on Mac

UPDF lets you crop PDF pages individually or entirely. It gives you complete control over cropping, whether you want to crop a single page or an entire document.

Here's the complete user guide and cropping options:

Open your PDF file in UPDF and click on the "Tools" button. Select "Crop" from the Toolbar.

Inside the "Crop" feature, you'll find the following categories:

• Crop Pages
• Apply Changes
• Revert Changes
• Split a Page

Crop Pages

In the right toolbar, choose whether you want to Crop the page box or Crop the margins. Then, you can adjust the cropping area by dragging the purple dashed box. Click the purple "Apply" button to apply the cropping.

The size of the cropped frame is also customizable. The "Constrain Propertions" and "Apply Changes" button can also be enabled or disabled per your requirements.

Apply Changes

If you want to crop just the current page, click the "Apply" button on the top right corner.

If you want to make similar changes to the selected pages, enabling the "Apply Changes" feature will let you apply the current changes to the custom page range. You can also set the custom page ranges within this feature:

Restore Crop

You can restore the changes by clicking on the "Revert Changes" on the top toolbar.

Split a Page

In addition to cropping, UPDF also provides a Split option for dividing a PDF page. This feature allows you to add vertical or horizontal split lines, effectively splitting a page into two or four sections as individual pages. It is particularly useful when you've scanned a book and need to separate a single page into two, as shown in the screenshot below.

• Split Pages: It lets you cut a page into parts by choosing various Preset options to choose from.
• If you have a split template you use mostly, you can add it to the Starred section to access it immediately.

• Split Methods: It offers two Split Methods, such as Grid Split and Exact Split, and lets you choose accordingly.
• You can increase the number of parts you want to split the image into by clicking the  Plus and Minus icons on the Horizontal and Vertical options.

• Default Reading Direction: UPDF provides options to set a default reading direction in the right panel: Left to Right or Right to Left. These options accommodate cultural reading preferences, allowing you to choose the one that best suits you.
• Apply Changes: Like the Crop option, the Split feature includes an Apply Changes option, allowing you to set a specific page range for splitting. Additionally, you can enable Delete original page after splitting to remove the original page once the split is applied.
• Automatically Add to Starred: After doing all the changes, you can enable the Automatically Add to Starred to save the splitting template and apply it later on another document or page if needed.

Note: If you accidentally add any unnecessary split lines on your document page, UPDF offers the Remove Divider tab to undo the change.
