PDF Generation is the process of creating a Portable Document Format file, which is a widely used file format for sharing documents. This format preserves the layout, fonts, and images of the original document, making it ideal for printing and viewing on different devices. To generate a PDF, various software tools and libraries can be used, such as Adobe Acrobat or open-source options like PDFKit. Users can convert documents from formats like Word or Excel into PDFs easily, ensuring that the content remains consistent across different platforms.
