A major feature of Acrobat is the ability to digitally sign a PDF file. This feature enhances security and authenticity, allowing users to verify the identity of the signer and ensure that the document has not been altered since it was signed. Digital signatures use encryption techniques to create a unique cryptographic seal that ties the signer's identity to the document, providing assurance in legal and business transactions.

While some functionality exists in Acrobat for editing PDF files, it's typically limited and may not allow for complete or free editing due to the format's inherent characteristics designed for preserving layout and content. Converting a PDF to Word format is possible, but it might not always preserve the integrity of the original content and formatting. Additionally, printing a PDF in any size is a feature associated with many document formats and printing systems, but it doesn't provide the same level of security and verification that digital signatures offer.
