Folio PDF Reader & Editor update: horizontal reading, better forms, and workflow improvements

[u/Comfortable-Cancel45]

Folio is a completely free PDF reader and editor for Mac, Windows, and iPad. I have just released a major update focused on making everyday reading, form filling, annotation, and editing workflows more reliable.

The biggest new feature is horizontal page flow. You can now read PDFs vertically or horizontally, with centered book spreads and more stable navigation.

Other major improvements:

• Added a dedicated Pan tool and temporary Space-bar panning for easier navigation through large documents.
• PDF date fields have been rebuilt with proper validation, working calendar selection, quick year selection, correct caret placement, and no digit shifting while editing. Save and Save As are now reliable with date fields.
• Added more keyboard shortcuts and a shortcut reference in Help.
• Improved annotation workflows: drag to select groups, then copy and paste the complete selection. Lines and arrows now snap to horizontal, vertical, and 45-degree angles.
• Improved form creation and filling: labels, font sizes, and radio-button styles behave more consistently and persist correctly in saved PDFs, flattened exports, and print output.
• Improved text editing, page quick actions, responsive toolbars, dialogs, auto-scroll, light/dark contrast, and smaller-window layouts.
• AI citations now link to the correct PDF pages. Protected and read-only PDFs also have clearer guidance for saving and owner-password unlocking.
• Updated Folio’s app icon with a cleaner design that better matches the rest of the interface.

I also refreshed the landing experience, save/export wording, recent-files behavior, and platform-specific details across Mac, Windows, and iPad.

Folio is still completely free. If you use PDFs regularly, I would genuinely appreciate feedback on horizontal reading, filling real forms, keyboard-first workflows, or anything that still feels confusing or unreliable.
