Quick answer
PDF stands for Portable Document Format. It is a file format designed to preserve a document’s layout, fonts, images and structure so it looks consistent on different devices and operating systems.
A PDF helps ensure that a file looks the same when opened on Windows, Mac, mobile devices or in a browser.
Why PDFs exist
Documents often break when shared in editable formats like Word files. Fonts can change, spacing can shift and pagination may move. PDFs solve that by packaging the content into a more stable format.
