Reasons to consider using a PDF
- PDF can be printed or downloaded for later use.
- If the content is several pages in length, PDFs can be useful for a user who is printing or saving the content.
- PDF can be password protected within the file.
Reasons to avoid using a PDF
- The user is removed from the context and navigation of the website.
- Text may be written with a different tone and style and may not be optimized for web.
- PDF may not be designed to be read on a screen. Layout and content is static.
- Accessibility concerns around navigating the information and usability of PDF with screen readers and other devices
- Requires download, demands time and data to acquire information
- More time-consuming to update
- Put the contents of the PDF directly on a webpage. If you can take content out of your PDF, do so. It is a much more pleasant experience for website visitors to read the content on a webpage (assuming it has been appropriately styled for web) than to read a PDF. If you must include a PDF, consider providing the same information—perhaps in a more concise manner—on the webpage.
- If you use a PDF, show file size and type in the link. By indicating file size and type, you allow your visitor to decide to download or view the file.
- Keep PDF files as small as possible. Browsers often need to download the full file before rendering it. Long download times can mean visitors get impatient and leave the page or site before the PDF appears.
- Include navigation in your PDF. Include a table of contents, and make sure the page numbers are clickable so that your readers can easily navigate the document.
