What is a PDF (Portable Document Format) file?

Saved with the .pdf extension, it guarantees that text formatting, vector graphics, embedded fonts, and page layouts display identically across every screen and printer.

Why view and edit PDFs in a web browser?

Traditional desktop PDF software often requires expensive licenses, heavy installations, or cloud uploads that jeopardize confidential data.
