PDF - Portable Document Format

What is a PDF file

PDF, or Portable Document Format, was developed by Adobe. It displays documents the same way across different devices and programs, making them easy to share and print. PDFs can include text, images, and links, and they can be password protected and edited. Most PDF readers are free to use.

PDF files can be non-linear (smaller but slower to load) or linear (faster to load, especially in web browsers). You can optimize non-linear files with Adobe Acrobat.

PDFs can be interactive with features like videos, annotations, animations, 3D art, and attachments. They also support security measures like encryption and digital signatures.

They can be opened by almost any device and by any modern web browser. Programs that can open PDFs include:

• Bookize Reader
• Any Browser
• Adobe Acrobat Reader
• Adobe Viewer
