Online PDF Signer

The main function of Online PDF Signer is to sign PDF documents using digital certificates.

Long-term validation purposes – Using our software you can sign and timestamp PDF documents for long-term validation purposes. Online PDF Signer supports advanced digital signatures which include embedded RFC 3161 compliant secure timestamps. Such signatures can be verified even after the signer’s certificate expires or is revoked.

Invoice signing – Online PDF Signer allows organizations to digitally sign and process large numbers of invoices. EU VAT Directive requires that: “Invoices sent by electronic means shall be accepted by Member States provided that the authenticity of the origin and integrity of the contents are guaranteed”. The only standard and interoperable way of doing this is to use digital signatures and in general EU member states require that a qualified electronic signature is used to confirm the identity of the originator.
