View and Read PDF on iOS with UPDF

In UPDF for iOS, multiple PDF viewing modes are supported. Follow the steps below to change the viewing mode freely.

• Import a PDF file with multiple pages by tapping on the + symbol in the bottom right corner.
• Tap on the Reading icon on the bottom of the screen. Tap Page View.

• Let's take a look at these handy buttons from the pop-up window:

• Page View: This section allows you to choose between "Single Page" and "Two Pages" view modes for your document.
• ​Zoom (Actual Size)​:
  • Displays the current zoom level, which is 69% in this case. There is also a lock icon next to the zoom percentage, you can lock the zoom at the current setting.
  • "Fit Page": Adjusts the view so that the entire page fits on the screen.
  • "Actual Size": Shows the document at its real - life size as defined in the source file.
  • "Fit Height": Scales the document so that the height of the page fills the available screen space.
  • "Fit Width": Scales the document so that the width of the page fills the available screen space.
• ​Scrolling: This enables or disables smooth scrolling functionality within the document viewer.
• ​Vertical: You can decide whether to view the document horizontally or vertically — it’s up to you how you want to read it.
• ​Theme: You can change the overall color theme of the document-viewing interface.
• ​Eraser Settings:
  • "Pixel": A pixel-based eraser precisely removes content by deleting individual pixels.
  • "Object": Removes entire elements (like shapes, drawings, or grouped objects) as single units, rather than erasing individual pixels.
  • You could toggle on "Erase Pencil Only". This will limit erasing to only pencil marks, protecting other annotations.
