How to: PDF Viewer Preferences
- Select your PDF.
- Choose page layout, panel and window options.
- Download – the PDF opens your way.
First impressions matter: a brochure can open as a two-page spread, a manual can open with bookmarks visible, and a presentation can open full screen. Viewer preferences store these settings inside the PDF.
Common uses
- Open a magazine or brochure as two-page spreads.
- Show the bookmarks panel for long manuals.
- Open a PDF presentation in full-screen mode.
Tips for best results
- "Display document title" shows your title instead of the file name.
- Test in Adobe Acrobat Reader – browser viewers may ignore some settings.
First impressions
Viewer preferences control how a PDF opens: page layout, which panel is visible and whether the title or file name shows in the window. Setting them makes manuals, catalogues and presentations feel polished.
Combine with metadata
Set a document title with Edit PDF Metadata and enable “display document title” so readers see a meaningful name instead of a file name.
