The Most Advanced PDF Viewer on the Market

PDF Viewing and Navigation

Show single or double pages in side scrolling or continuous scrolling mode. You can also set whether a PDF page should be fully displayed or fit to width.



The thumbnail view is fully customizable. You can increase the thumbnail size and change how pages are numbered, or disable thumbnail mode if you prefer a scrolling thumbnail bar instead.


PSPDFKit features a fast and accurate outline (table of contents) parser that deals with all custom variants and PDF action types. Long outlines are wrapped into multiple lines, and actions can be fully customized or replaced.


PSPDFKit provides a rich bookmark UI that enables your users to add, remove, and sort bookmarks. Bookmarks made in a PDF document show a thumbnail and an excerpt of the bookmarked page for easy reference. The bookmark API also allows you to substitute your own UI or use your own bookmark provider.
