Part 1. Types of Signatures in PDFs

Before using a signature extractor from PDF or trying to copy signature from PDF, it helps to understand what type of signature is inside the document. Not all PDF signatures work the same way.

Image or Handwritten SignaturesThese are scanned or drawn signatures added as pictures. They behave like regular images, so they are the easiest to extract or copy.
Digital (Certificate-Based) SignaturesThese signatures use encryption to verify the signer's identity and protect the document from changes. They are not simple images, so extracting them requires special methods.
Approval or Workflow SignaturesOften used in business processes, these show that someone reviewed or approved the document. A single PDF may contain multiple approval signatures.

Part 2: How to Extract Signature From PDF --- Accurate OCR

Scanned or image-based PDFs usually do not let you select anything. To copy signature from PDF or cut and paste signature neatly, OCR is the best solution. PDNob uses smart AI OCR to turn locked or scanned PDFs into editable files. This makes the signature selectable, so you can extract it clearly without damaging the document.
