PDF Signer

PDF Signer is a handy tool to sign multiple PDF files in bulk, which is particularly helpful for corporate use.

It supports a variety of certificates, from those issued on smart cards, USB tokens, eTokens, DSC, QSCD to eIDAS digital certificates, complying with the EU Regulation.

PDF Signer allows you to personalize the appearance of your digital signatures. You can decide exactly where the signature will appear: on the first page, last page, or on all pages, change the depiction's position, font type and size, add labels, images and customize it in many other ways.

The program also shines in its long-term validation function, which not only signs but also timestamps PDF documents for future verification needs. The RFC 3161 compliant secure timestamps embedded in advanced digital signatures guarantee the document's authenticity even after the signer's certificate expires. PDF Signer also incorporates SHA-256, SHA-384, SHA-512, and RSA 2048 to digitally sign and time-stamp PDF documents.

Lastly, PDF Signer goes beyond just signing by enabling document certification. This allows users to express approval of the document content, adding another layer of authenticity. Overall, it's a comprehensive, efficient, and secure tool for handling and certifying bulk documents.
