MultiPage PDF Viewer is a macOS PDF viewer that displays multiple pages at once. It is designed for reading, so it reduces the visual clutter common in editing-focused PDF tools and helps you stay focused on the document. It prioritizes responsive rendering for comfortable multi-page viewing. In addition to 1-4 page presets, you can freely adjust rows, columns, and reading direction. It improves workflows such as document comparison, vertical-monitor reading, and sheet music viewing. It also supports reopening from recent files, password-protected PDFs, and per-document display-state restore. Main Features Multi-page display: You can switch between 1/2/3/4-page presets and detailed layout settings. Up to 15 pages can be displayed at once. Row/column and reading-direction customization: You can optimize page order with row-first/column-first and left-to-right/right-to-left settings. Start-page offset setting (page-number correction): You can adjust displayed page numbering, for example by treating the main body as page 1 after excluding cover or index pages. PDF loading: Both drag-and-drop and "Open..." are supported for quick access. Recent-file reopen: You can reopen recently used files quickly from the recent list. Password-protected PDF support: You can open protected PDFs and optionally save passwords. *Some PDF files may not be accessible. Per-document display-state restore: Layouts and page positions are saved per document and restored when reopened. Printing: You can print the current PDF directly from the app. Foot-pedal operation: If your foot pedal can send arrow keys (β/β), you can use it directly for page turns.
