I'm sure you have either been told or find yourself telling other people that you should avoid PDFs at all costs. But can you always remember the reasons why that might be a good idea?

Enter this page in the NHS service manual, which says:

Creating a new PDF document is a last resort and you should avoid it unless there is a specific user need for it. You should always provide an HTML version too.

Not only can you use this page to bolster your no-PDFs argument, it also includes examples of when you might really need to use a PDF and, if so, how to do it in the best possible way.
