Crop PDF: frequently asked questions

Is cropped content deleted?
No. Cropping changes the visible area of the page, so the trimmed content is hidden rather than erased. To remove sensitive content permanently, use Redact PDF.
Can I crop just one page?
Yes. Enter the page numbers in the Pages field, for example 1 or 2-4. Leave it empty to crop every page.
Does cropping reduce quality?
No. Text and graphics are not re-rendered, so they stay exactly as sharp as before.
Is my file uploaded?
No. Cropping runs in your browser, so the PDF stays on your device.
