What file extension do Adobe Acrobat files have?

Adobe Acrobat files are saved with the .PDF file extension, standing for Portable Document Format. This format was specifically designed to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. Using .PDF as the file extension allows for the encapsulation of complex documents, which can include various elements such as hyperlinks, forms, and even multimedia, making it a popular choice for sharing and preservation of files across various platforms.

The other file extensions listed are associated with different types of documents: .DOCX is used for Microsoft Word documents, .TXT is for plain text files, and .XLSX pertains to Microsoft Excel spreadsheets. Unlike the .PDF format, these file types typically require specific software to open and edit, and they do not maintain the same level of formatting consistency across different systems as PDFs do.
