Hi there,

Thank you for reaching out to pdf.js express forums,

pdf.js does not support digital signatures, please consider migrating to Apryse’s WebViewer for this support:

> **[Digital Signature in JavaScript PDF Viewer | PDF.js Express SDK](https://pdfjs.express/documentation/advanced/digital-signature)**

Best regards,  
Kevin Kim

Pdf.js, Apryse and PDFTRON, are from the same company?

I recently purchased an annual pdf.js view license

Hi there,

PDFTron rebranded to Apryse, and pdf.js falls under Apryse as a secondary product.  
Please note that pdf.js and Apryse SDK have separate license and I believe the above screenshot you provided falls under Apryse WebViewer.

Best regards,
