Add comments in a text box or callout

Note: In Reader, commenting tools are available only in PDFs that have commenting enabled. PDFs in a review workflow typically include commenting rights.

You can use the Text Box tool to create a box that contains text. You can position it anywhere on the page and adjust it to any size. A text box remains visible on the document page; it doesn’t close like a pop-up note.

Another way to add a text box is simply to paste copied text into the PDF. Text font and size are based on the system default settings.

Note: You can add comments to Japanese, Chinese, and Korean text with the Text Box tool, but you must have the Asian-language resource files installed. Text boxes allow for horizontal text only.

You can use the Callout tool  to create a callout text box. Callout text boxes are especially useful when you want to single out—but not obscure—a particular area of a document. Callout text boxes have three parts: a text box, a knee line, and an end-point line. You can resize each part by dragging a handle. The knee line can be resized in one direction only; horizontal knee lines can be resized horizontally only; vertical knee lines can be resized vertically only. The text box expands vertically as you type so that all text remains visible.

You can move the text box itself or together with the end-point line. The text box moves around a stationary anchor point—the arrow on the end-point line—which is created when you first click in the PDF. You can modify the color and appearance of the text box and add arrows or leaders to the end-point line.
