Frequently asked questions

What does cropping a PDF do, and why would I need it?▾

Cropping changes the visible page boundaries of a PDF without touching the content underneath, so wide margins, printer marks, or scanned page borders are hidden from view. People crop PDFs when a scanner captured extra background around a document, when a textbook page has wide margins that waste space when printed two-up, or when a slide deck exported with unwanted white space around the content. Photographers and designers crop PDF proofs to focus a client's attention on the artwork rather than the surrounding page. Because the underlying content is only hidden, not deleted, you can crop again with a different box if the first attempt trims too much or too little.

Does cropping apply to every page?▾

Yes. The crop you set on the page-1 preview is applied as the same relative percentages to every page in the document.

Can I crop just one side or an irregular shape?▾

Yes. Drag any edge or corner of the crop box. Thin and Wide presets start with equal margins on each side; you can reshape freely from there.

Will hidden content be deleted?▾

No. Cropping only hides content outside the crop box; it is not a redaction tool and should not be relied on to remove sensitive information.

Can I change or undo a crop after downloading?▾

Cropping does not delete page content, so you can crop the same file again with a wider box to reveal margins you hid before. If you already downloaded a cropped copy, upload that file again and adjust the crop box, or start from your original PDF if you saved one.

Is the PDF uploaded to crop it?▾

No. The crop boxes are changed locally in your browser with pdf-lib. Your document is not sent to Justools servers.

What are the limits?▾

One PDF up to 25 MB per crop job.

Processed locally in your browser. Your files are never uploaded to our servers.
