Viewing & Navigating on iOS devices

Navigate to documents just as you would in Apple's Files app. (See Opening Folders & Documents).

Once you open a document from the Files / Document view, you will enter Page view. Nitro PDF Pro provides three main modes: Reading, Editing, and Fullscreen.

Switch between Reading and Editing modes by tapping on the Reading or Editing icon located in the middle of the Toolbar. By default, PDF Pro will land in Reading mode.

Reading Mode
This is the default mode upon launching a document. Reading mode hides annotation and editing tools to allow users to focus on the reading experience. Basic Toolbar controls including Searching, Settings (scrolling options), and Sharing are still available in this mode.

Editing Mode
Editing mode reveals the Editing bar which provides annotation and editing tools. All Toolbar controls are available in this mode.

Fullscreen Mode
Single tap anywhere on the page to enter full screen mode and make the Toolbar disappear. Tap again to exit full screen mode, and the Toolbar will reappear.

• Weak: RC4–40 level encryption. A document secured with this level of encryption can be viewed by most PDF viewers. 
• Strong: AES–128 level encryption. A more secure encryption that can be deciphered by fewer PDF viewers. 
• Strongest, Least Compatible: AES–256 level encryption. One of the latest and most secure encryptions. It can only be viewed by PDF viewers which have been updated to support it.
