When it comes to verifying an important legal or business document these days, a handwritten signature or wax seal just won't cut it for most people! That's where PAdES comes in. In this guide, we'll talk you through how the PAdES format works to provide quick, secure electronic signatures.
PAdES is a technical standard for PDF documents and refers specifically to a set of restrictions and extensions for electronic signatures in the format. Essential to the workflow of corporate documents, it allows you to put a unique, secure digital stamp on your work.
In an age where manually signing physical documents is not flexible or efficient enough for many, it’s a big reason why digital PDFs have become the trusted option for numerous individuals and companies around the world.
PAdES is an acronym - and stands for PDF Advanced Electronic Signatures. The ‘advanced’ part of the name points to the upgraded security and validation methods it provides for electronic signatures on documents.
The concept of electronic signatures forms a key part of the history of PDFs, and was first introduced with PDF version 1.3 in 1999. This marked a big leap forward, but there were some issues with interoperability, particularly across borders between countries who may have different standards.
After the Electronic Identification, Authentication and Trust Service (eIDAS) directive was passed to standardise electronic signatures in the European Union and European Single Market, PAdES introduced a number of key features to meet this directive and reduce the risk of interpretational problems.
PAdES signatures are legally binding in the EU and frequently play an important role in sharing and verifying electronic signatures in both a business-to-consumer and business-to-business context.

One of the key purposes of PAdES files is identification. With PAdES, you can provide a unique electronic signature. This is in turn associated with a digital signing certificate, which shows that the signature is authentic and has not been tampered with.
In professional settings, PAdES files can be used to maintain a digital paper trail between authors, editors and those who might have overall sign-off or oversight of the document.
As a result of its advanced identification features, PAdES helps prevent fraudsters from creating forged documents. For one thing, the end-user can verify who has created and signed the document. But the files also provide security measures to stop non-authorised users from viewing editing the document in the first place.
It’s worth noting that PAdES signatures can only be used for PDF files. This means that if you work with other documents like DOCX, XLSX or HTML, you’ll need to find an alternative signature format. Of course, you can also easily convert files to the PDF format online, which will then allow you to implement PAdES.
