Define the Different Versions of PDF/A Example, and Types

PDF files are now used in our daily lives, whether you’re a student or a professional. They used to submit assignments, apply for jobs, send reports, or review contracts. The PDF file opens exactly the way it was created, with no broken layout and no missing fonts. That is why PDF files are compatible with all devices.

PDF now exists in several versions, and each type solves a different problem. Some are built for long-term storage, others support precise printing, and a few serve technical or engineering needs. You can take advantage of it by knowing which type suits your project, so let’s explore what a PDF is, its types, and the specifications of each. 

What Does PDF Mean?

PDF is a portable Document Format that is designed to hold text, images, links, and buttons. It is used for both personal and professional purposes. You can use it to send reports, brochures, forms, or proposals. 

For example, you can use the PDF file to lead the reader directly to landing pages, product demos, or sign-up forms through clickable links. That way, you can guide them exactly where you want them to go without losing the design or formatting.

Now, you don't have to stick to a specific format; instead, you can choose from different types of file formats that best suit your projects.
