Crop PDF page margins and unwanted outer areas

Use Crop PDF to hide scanner borders, excess white space, or unwanted outer page areas. Preview the visible boundary before creating the cropped copy.

Preview the visible crop boundary

Adjust the supported crop controls and review which page area will remain visible before processing.

Apply consistent crop margins when supported

Use the same crop percentages or boundaries across pages only when that matches the source document layout.

Do not use cropping as secure redaction

Cropping changes each page's CropBox, but hidden or clipped PDF objects remain in the document. Use Redact PDF for sensitive information.

About this tool

Adjust the visible area of PDF pages

Crop PDF changes page boundaries so unwanted outer areas are no longer shown in normal viewing. It is intended for page presentation, not removal of sensitive page content.

Useful for

  • Remove scanner borders or excess white space.
  • Create consistent visible margins across pages with similar layout.
  • Focus the visible page area on the main document content.

Good to know

  • Apply one crop to all pages or choose Current page only to store a different crop for each page.
  • Cropping may alter page boxes without deleting underlying objects.
  • Do not describe crop as permanent secure removal of hidden content.

Crop PDF questions

Can I preview the crop before downloading?

Yes. Use the live page preview and crop box before applying the crop.

Can different PDF pages use different crop areas?

Yes. Choose Current page only for a per-page crop, or apply the current crop to all pages.

Can I enter exact crop margins?

Yes. Enter top, right, bottom, and left percentages from 0% to 90% in 0.1% steps, or adjust the crop box visually.

Does cropping reduce PDF quality?

No image recompression is applied. The tool changes PDF CropBox values and keeps the underlying page content.

Will cropping permanently remove sensitive information?

No. Cropping changes visible page boundaries but leaves underlying page objects in the PDF. Use Redact PDF for sensitive information.

Are my files uploaded?

No. Selected PDF contents are processed locally in this browser.
