A PDF (Portable Document Format) file is a type of file format for digital documents that was developed by Adobe in the 1990s. It allows users to create documents that can be viewed and printed on any device, regardless of the software or operating system that was used to create the original document.
PDF files are widely used for a variety of purposes, including but not limited to, creating and sharing documents, manuals, forms, eBooks, and more. They can be created using a variety of tools such as Adobe Acrobat, Microsoft Office, or online converters, and can be viewed using free PDF readers such as Adobe Acrobat Reader or other alternative PDF readers.
One of the main advantages of PDF files is that they preserve the formatting of the original document, including images, fonts, and layout. Additionally, they allow users to add annotations, signatures, and other interactive elements to the document, making them useful for a range of applications, from legal contracts to academic research papers.
