The Portable Document Format (PDF) is a popular format developed by Adobe for delivering formatted text and images. A PDF file includes a complete description of all layout elements, including text, fonts, images and layers, ensuring that the file will look identical when opened on any device. The PDF format also has the big advantage of compressing high-quality files to a relatively small file size.
Cloudinary offers an interesting feature: The ability to generate images from the PDF files and pages. With Cloudinary, you can create thumbnail images of your documents for previewing purposes. It's useful when you don't want to grant user access to the content, but need to give them a sneak peek of what they're missing if they haven’t downloaded the PDF yet.
