PDF

PDF stands for Portable Document Format. It is a file format developed by Adobe Systems in the early 1990s to present documents consistently across different devices, operating systems, and software applications.

A PDF file preserves the fonts, images, graphics, and layout of any source document, making it ideal for sharing and printing. It is widely used in graphic design, publishing, and business for distributing read-only documents that maintain their formatting regardless of the viewer's platform.

Key features of PDFs include:

• Cross-platform compatibility
• Fixed layout
• Support for text, images, vector graphics, and interactive elements (like hyperlinks, forms, and buttons)
• Security options, such as password protection and digital signatures
• Compression capabilities to reduce file size without significant quality loss

PDFs can be created using design software like Adobe InDesign, Illustrator, Photoshop, or exported from word processors like Microsoft Word.
