Now that you know PDF’s commendable features, find below some business use cases for PDFs:   

#1. URL to PDF

The ability to convert URLs to PDFs is a great utility for businesses. You no longer need to create and host PDF files. Also, you can escape investing time in reviewing, renaming, and securely storing PDFs in several backup drives.

Another business use case for PDFs is generating a portable document file from business apps like Microsoft Word, PowerPoint, Excel, Google Analytics, Project Management tool, etc., for sharing purposes.

But, you are sure that the recipient can easily open the PDF file using a web browser or the preview tool of most computer operating systems.   

#3. PDF Annotation


PDF’s business utility and popularity are not just for its app-less readability or portability. You can easily edit its several components using simple computer software or mobile apps. For business needs, you can easily add comments, correct sentences, highlight content, add images, create bookmarks, build document thumbnails, create document outlines, and so on.   

#4. Compress PDF

PDF compression to reduce the original document size is another business importance where:

  • A business emailing client or software allows very limited file size
  • You are creating an archive of PDFs
