The history of PDF as a format goes back to the early 1990s - it was designed to present and exchange documents reliably, regardless of software, hardware, or operating system. PDFs maintain the original formatting, fonts, and images, ensuring that documents appear the same on any device.

Due to these advantages, PDFs have become the global standard for sharing documents in various industries, including business, education, publishing, and government.
