Mark up a PDF in OneDrive for iOS

Use the Markup tool in OneDrive for iOS to add notes, text, pictures or freehand markup to PDF files.

When you open a PDF file from OneDrive on your iPad, iPhone or iPod Touch, the Markup tool appears at the top, along with other common PDF commands such as print or search.

  • Tap the Eraser to erase your freehand markups made with the Pen or Highlighter function. (You can do this freehand with a Pencil or stylus, or with your fingertip.)

  • Tap the Pen to draw or write freehand, with a Pencil or stylus, or your fingertip. To customize your Pen's look, tap the small circle in the bottom right, then select the color, size, and transparency of your Pen.

    You can customize all three Pens differently as needed.

  • Tap the Highlighter to highlight freehand, with a Pencil or stylus, or your fingertip to accent text or images. To customize your Highlighter's look, tap the small circle in the bottom right, then select the color, size, and transparency of your Highlighter.

    You can also set your Highlighter to either Text or Freehand. Text will only highlight text, while Freehand lets you highlight icons, images, and other non-text information in the PDF.

  • Define - Accesses a dictionary to provide the definition of the selected word

  • Highlight - Highlights the selected word using your current Highlighter settings

  • Underline - Underlines the selected word

  • Strikethrough - Adds a strikethrough over the selected word

Change or delete markup

  1. Open the PDF, then tap the Markup icon.

  2. Tap any markup to select it.

  3. A set of tools and commands also appears, with options including Copy and Delete.

    Tip: The tools that appear will be different depending on the type of markup you're changing. For example, the tools offered to change freehand markup are different than those for text markup.
