Frequently asked questions

Does cropping remove content permanently?

Cropping in PDF adjusts the visible area (crop box) but the hidden content is still in the file. Use Flatten PDF after cropping if you need to remove it permanently.

Can I crop all pages at once?

Yes. You can apply the same crop margins to all pages.

Is my PDF uploaded?

No. Cropping runs securely in your browser without uploading.
