If you would like to add digital signatures to your document, PDFTron’s Webviewer allows precise identification of who created/signed a document while validating the contents of the document after it has been signed. Digital signatures are different from e-signatures since it uses a cryptographic algorithm to uniquely identify the author.
PDFTron’s WebViewer uses PDFTron’s proprietary rendering engine, without reliance on open-source technologies and allows for more advanced capabilities like digital signatures directly through the browser.
Please follow the guide to migrate from PDF.js Express to PDFTron’s WebViewer.
Once you have PDFTron’s WebViewer up and running you can reference the guide for digital signature features.
