What the PDF?

PDF is apparently a lot of things.

  • PDF. This PDF file type is seen as the ‘standard’ PDF format. It is often used for sharing and viewing files online.
  • PDF/A. This type of PDF file is often used by managers and archivists who require long-term file storage. It also has a restricted set of features, including JavaScript, audio and video content.
  • PDF/E. This format supports construction, engineering and manufacturing specifications and is often used in those industries.
  • PDF/X. Commonly used by graphic designers and print professionals, this PDF file type is designed to better support graphics when sharing and printing.
  • PDF/VT. This file is similar to the PDF/X format but features additional customisation features. Again, the PDF/VT file type is most suited to print professionals and graphic designers.
  • PDF/UA. This type of format is compatible with assistive technology, enhancing readability and navigation for people with disabilities.
  • PAdEs. Sets the standards for PDF Advanced Electronic Signatures in line with major legislation.
  • PDF Healthcare. This standard was developed to secure best practice for handling and managing healthcare information.
  • Searchable PDF. A searchable PDF is essentially a standard PDF file with a search function. The basic function of a searchable-PDF is to make image-based PDFs text-searchable.
