What is a PDF file?
A PDF file is a widely used document type that maintains the original layout and formatting across different devices and operating systems. It is often used for sharing documents, such as reports, contracts, manuals, or forms, ensuring that the content appears the same for all users. PDF files can include text, images, annotations, and even interactive elements (e.g., buttons and checkboxes), and users typically create them from other file formats, such as Word .DOCX documents, Excel .XLSX spreadsheets, and images.
More Information
You may encounter PDF files in various ways, whether downloading a document from a website or receiving a document from a co-worker or friend as an email attachment. PDF files also preserve fonts and formatting electronically across multiple platforms and appear the same on the screen as when printed on paper.
Creating PDF files
You may create PDF files with various programs, including word processors, image editors, and PDF file utilities like Adobe Acrobat. You may also create PDF files from documents using the Print dialog in Windows and macOS.
For example, in Windows, you can select or click the printer icon to open the Print dialog within an application. Then, select from the list of available printers in the Print dialog box and click to create the PDF file. In macOS, you can choose from the application's menu, and then select from the PDF dropdown menu in the window.
