Adobe Acrobat Reader

Adobe Acrobat Reader is a free software application for viewing, printing, and commenting on PDF documents, available for Windows, macOS, and mobile platforms. It lets users open PDF files, fill forms, add highlights and sticky notes, and sign documents electronically, with cloud storage integration for accessing files across devices. The reader supports accessibility features and can handle interactive PDFs with multimedia and form fields. As one of the most widely used PDF viewers worldwide, it is commonly the default choice for reading official, academic, and business documents, and it connects with paid Acrobat services for advanced editing, conversion, and e-signature workflows.
