We are often asked if content can be published in PDF format as this is a popular way of sharing documents.
The recommended format for web content is as an HTML publication. This is a time-stamped publication that opens in a web browser.
Content must be accessible for all users
The reason we prefer HTML to PDF is that HTML documents are more accessible for users.
It is important that users are able to quickly and effectively find information using desktop, mobile and tablet devices.
We have a commitment to make our service accessible for anyone who needs it.
The benefits of HTML
HTML documents are better for users because they:
- are more accessible in terms of font, tagging and metadata
- are easier to search and find online
- are optimised for swipe screen
- fit specification of assistive technologies, such as screen readers
- can be quickly updated
- create fewer problems when linked to (PDF links break when they are updated)
- comply with open standards principles
- get higher user engagement
The drawbacks of PDFs
While PDFs are a useful document type for sharing internally, we try not use PDFs to share information on the web because they:
- cannot be easily found through search engines
- adapt poorly to different screen sizes and devices
- are difficult to update
- are less likely to be compliant with accessibility legislation
- have lower user engagement
