What is PDF Document Validator?

PDF Document Validator is a tool that verifies whether a signed document is valid and sealed with GlobalSign. It checks details about the transaction, the certificate, and the sealing process, helping you confirm if the document was signed and sealed correctly.

GlobalSign is used as the certificate authority. As a trusted provider of digital certificates, GlobalSign ensures documents are authentic, unchanged, and protected against tampering once sealed.


How does PDF Document Validator work?

The validation process is quick and simple:

  1. Access the tool via this URL https://validatedoc.net/documentvalidator

  2. Upload the PDF document you wish to validate by clicking the "Upload Document" button

  3. The tool analyzes the document and generates a validation report

You’ll be able to see if the document is properly signed and whether the certificate used to seal it remains valid and intact.
