How do I crop pages in Adobe Acrobat to adjust the PDF size?

Open your PDF in Acrobat. Go to the Edit menu. Click Crop pages. Draw the area you want to keep. Apply the crop and save your file.

What does cropping a page in Acrobat actually do?

Cropping a page in Acrobat hides everything outside the area you select, but it does not really delete it. The hidden parts are still in the file and can be brought back later. Cropping is good for making a page look cleaner, but it is not the same as erasing data.

If my scan has big black borders, can cropping help make it look better?

Yes, cropping can hide the black borders so only the main part of your scan shows. This makes your PDF look cleaner and more professional.

Why is it important to sanitize after cropping in Acrobat?

It is important to sanitize after cropping because cropping only hides the parts you do not want, but does not delete them. If you share the PDF, someone could recover the hidden data. Sanitizing removes these hidden parts, making sure no one can see or restore them. This is very important if your document has private or sensitive information outside the crop area.

How is cropping in Acrobat different from resizing a page?

Cropping Resizing. Hides parts outside the crop box Changes the whole page size Content is still there, just hidden Content is adjusted to fit new size Can be undone May change layout or scale
