Fragment Identifier

What is Fragment Identifier?

Fragment Identifier is a feature defined in Annex O of ISO 32000-2, allowing specific content anchoring and display control within linked PDF files using URLs. These identifiers follow the # symbol in a URL, influencing the displayed content.

For instance, you can refer to a particular PDF page by adding #page=n (where n starts from 1) to the URL: takes you to the PDF's 5th page.
