Tips
- Drag to draw a crop area on the preview. Leave as-is to keep the full page.
- Use “Keep cropped size” to keep the crop box dimensions; other sizes will center the crop within the chosen paper.
- Margins add extra white space around the cropped content.
How to crop and resize pages without surprises
Separate crop from paper size
Cropping decides which part of the original page stays visible. Page size decides the final sheet size around that content, so review both settings before you export.
Use “Keep cropped size” when the crop box is final
This option keeps the cropped dimensions instead of centering the crop on a new paper size. Turn it off when you want every page normalized to A4, Letter, or another fixed target.
Margins add space after resizing
Margins do not change the crop itself. They add extra white space around the output page, which is useful for binders, annotations, or print-safe edges.
Preview checklist
- Check that the crop box excludes unwanted headers or scanner borders.
- Confirm the target paper size before batch-exporting many pages.
- Use the preview once more after changing margins so content does not look unexpectedly small.
FAQ
What is the difference between cropping and resizing?
Cropping removes unwanted areas from the visible page. Resizing changes the final paper size that the cropped content is placed on.
What does “Keep cropped size” do?
It exports the page using the crop box dimensions instead of fitting that crop inside a new target paper size. Use it when you want the crop to become the final page.
Why did extra white space appear around the page?
White space usually comes from margins or from centering a cropped area on a larger target size. Reduce margins or switch to “Keep cropped size” if you want a tighter result.
Are my PDFs uploaded anywhere?
