Features

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.

Guides

Thumbnails

The thumbnail view is freely resizable — with the thumbnails adapting in size as needed — and can show either page numbers or page labels.

Guides

Outline

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.

Guides

Bookmarks

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.

Guides

Dark Mode

PSPDFKit for Web comes with two themes: a bright one and a dark one. You can easily enable either to help your users work with documents. You can also separately switch the page rendering style with ease — either programmatically or through the built-in settings UI — to fit your app’s requirements.

Guides

Responsive
