Why PDF is Everywhere
PDF's consistency and reliability make it the go-to format for both professional and personal use. Whether you're submitting an application, distributing a digital report, or sharing a scanned document, PDF ensures that text, images, and graphics remain intact. PDFs can include interactive elements, hyperlinks, and even embedded media, offering more than just a static page.
