Frequently asked questions
Will cropping the margins cut off any of my text or images?
No. The tool detects exactly where your actual content sits and removes only the surrounding empty white space, so all text and images stay fully intact and readable.
Is it safe to upload my PDF here?
Yes. Your file is sent over an encrypted connection and processed on a secure server, then deleted shortly after. It is never shared, so confidential documents stay private.
Can I crop every page in one go?
Yes. The tool analyses each page individually and trims its margins automatically, so a long document with varying layouts is cropped page by page in a single pass.
Is there a file size limit for cropping?
The tool handles typical everyday PDFs comfortably. Very large or high-resolution scanned files simply take a little longer to upload and process before your trimmed PDF is ready.
Does it work on my phone or tablet?
Yes. The cropper runs in any modern browser on Windows, Mac, Android, and iOS, with no app to install, so you can tidy up margins from your phone or tablet.
How does automatic cropping decide where the content ends?
The tool analyses each page, finds the bounding box of the actual content, and trims the surrounding white space. That means uneven scans, oversize margins and extra border space are all handled page by page, without you drawing crop rectangles manually. Always review the output, because a faint scan speck can occasionally be treated as content.
Can I crop only selected pages of a PDF?
Cropping is applied to the document as a whole. If only some pages need trimming, split the file first, crop the part that needs it, then merge the pieces back together in order. That workflow also lets you use a different treatment on different sections — for example, tight margins on scans and untouched pages for digitally created pages.
Will cropping cut off page numbers, headers or footers?
Anything inside the detected content area is kept, including page numbers, headers and footers, because the tool trims only the blank space around the content. If a header sits very close to the paper edge with almost no white margin, increase the safety range or crop that page separately — and check the first pages of the result carefully.
Does cropping reduce the file size?
Usually only slightly. Cropping changes the visible page area rather than the underlying image data, so the content itself is not re-encoded. If you also need a smaller file, run the cropped PDF through Compress PDF afterwards — that step does re-encode images and typically delivers the real size reduction.
Is my file uploaded when I crop it?
Yes — this tool uses the conversion server, so your PDF is uploaded over an encrypted connection, processed and then discarded; nothing is stored or shared. If a document must never leave your device, use a browser-only tool such as Organize PDF or Split PDF instead, which process files locally without any upload.
