About Crop PDF

Scans often have black edges or oversized margins that waste space on phone screens and e-readers. Cropping to the content makes the text larger without changing the file’s resolution.

Cropping sets the page’s crop box rather than deleting content, so it is reversible in a PDF editor and does not degrade quality.

How it works

  1. Drop PDF file onto the box above, click it to browse, or paste from the clipboard.
  2. Adjust the options if you need to — the defaults suit most cases.
  3. Press Convert. The work happens on your device, so speed depends on your computer or phone.
  4. Download the result.

About the format

PDF · Portable Document Format · .pdf

The fixed-layout document standard: looks the same on every device and printer, which is why forms, invoices, contracts and reports are shared as PDF.

  • A PDF can contain vector text, embedded fonts, images, form fields, annotations and digital signatures.
  • Scanned PDFs are just pictures of pages; they need OCR before the text can be searched or copied.
  • PDF is an open ISO standard (ISO 32000) since 2008.
