PDF Cropping vs Image Cropping: Which Should You Use?

Published: Oct 19, 2026 | Updated: Oct 19, 2026 | About (Japanese)

Key points

Tell whether the target is a PDF or an image
For PDF margins, crop the PDF
For part of a photo, crop the image

"Crop" can mean cutting a page of a PDF or cutting an image (photo). Use each for its purpose.

PDF cropping (Crop PDF Margins)

Target: whole pages of a PDF
What it does: trims page margins; makes all pages the same size.
Text: selecting and searching still work.
Good for: handouts, papers, scanned PDFs

Image cropping (Crop & Rotate Image)

Target: images such as JPG and PNG
What it does: cuts to any area or ratio (such as 4:3); rotates.
Good for: ID photos, screenshots, part of a photo

A rule of thumb

You want to reduce the margin around a PDF page → crop the PDF
You want to use only part of a photo → crop the image
You want part of one PDF page as an image → turn the page into an image with PDF to Images, then crop the image

Combining them

You can also crop a photo, make it a PDF with Photos to PDF, and tidy the margins with PDF cropping if needed.
