About PDF Viewer Preferences

PDF files can embed Viewer Preferences that control how the document appears when opened in a PDF viewer application. For example, you can set the page layout to single page, two-column, or two-page spread; specify whether bookmarks, thumbnails, or full-screen mode should be active on open; and control window-level options like hiding the toolbar and menubar, centering the window, fitting the window to the page size, and displaying the document title in the title bar.

You can also configure the initial zoom level—fitting to page, height, width, or custom percentage—and specify which page should display when the file is first opened. These settings are useful in many scenarios: full-screen presentations, e-books with facing page layouts, corporate documents with automatic bookmark panels for easy navigation, and kiosk-mode displays where toolbars should be hidden. This tool also includes an option to remove all existing preferences, returning the PDF to its default viewing state.

This tool uses pdf-lib for entirely browser-based processing, so even confidential documents can be safely modified without uploading to any server. Optimize your PDF viewing experience without expensive software like Adobe Acrobat.

How to use PDF Viewer Preferences

Click the download button to save the PDF with your viewer preferences applied.
