A PDF will look the same whether you’re viewing it on a computer running Windows, a Mac, or a mobile device, guaranteeing a consistent viewing experience for all users.
Security: To prevent unintentional access or modification of confidential data, PDF provides a number of security features. Users can add digital signatures to confirm the truthfulness of documents, limit printing or editing permissions, and encrypt PDF files using passwords.
Compactness: PDF files are incredibly small and therefore simple to send by email or post to websites, even when they comprise rich text, photos, and multimedia contents.
What is PDF and its types?
Adobe Systems developed the Portable Document Format (PDF) format for files in the early 1990s.
