Annotate PDF: Helpful tips
The Annotate PDF tool is simple and easy to use, but it helps to know the following tips for getting the most out of it.
You want to remove an annotation
Sometimes after you add a highlight, note, or drawing, you might change your mind. If this happens, you can easily fix it within the Annotate PDF tool.
You need to change the page formatting
If the file uploads in a wonky way, you may want to rotate it to landscape view to leave an annotation on a chart.
You’re unable to highlight or mark certain text
This can happen if you’re working with a flattened PDF document, which essentially saves the document layers—such as images or text—as an image.
The document is locked
If you are having trouble viewing the PDF or adding annotations, it may be because it’s password protected. Some PDFs have “view-only” restrictions, and these must be removed in order to make edits.
