Portable Document Format (PDF) is a file format that preserves the layout and appearance of a document, regardless of the software or platform used to view it. PDF files can contain text, images, hyperlinks, and other elements, making them versatile for sharing and archiving documents.
What does PDF mean?
Portable Document Format (PDF) is a file format developed by Adobe in 1993.

PDFs are popular because they are platform-independent, meaning they can be opened and viewed using free software such as Adobe Reader and other compatible PDF viewers. This universal accessibility makes PDFs a convenient choice for sharing documents with individuals using different operating systems and devices. Additionally, PDF files support various security features, such as password protection and digital signatures, ensuring the confidentiality and integrity of Sensitive Information.
