| Link | 2 | A link annotation represents either a hypertext link to a destination elsewhere in the document or an action to be performed. | |
| FreeText | 3 | A free text annotation (PDF 1.3) displays text directly on the page. Unlike an ordinary text annotation, a free text annotation has no open or closed state; instead of being displayed in a pop-up window, the text is always visible. | |
| Line | 4 | A line annotation displays a single straight line on the page. When opened, it displays a pop-up window containing the text of the associated note. | |
| Square | 5 | A square annotations display a rectangle on the page. When opened, it displays a pop-up window containing the text of the associated note. | |
| Circle | 6 | A circle annotations display an ellipse on the page. When opened, it displays a pop-up window containing the text of the associated note. | |
| Polygon | 7 | A polygon annotations displaya a closed polygon on the page. Such polygons may have any number of vertices connected by straight lines. | |
| PolyLine | 8 | A polygon annotations displaya a polygon on the page, with any number of vertices connected by straight lines. Unlike a polygon annotation, the first and last vertex of a polyline annotation are not implicitly connected. | |
| Highlight | 9 | A highlight annotation appeara as a highlighted text in a document. When opened, it displays a pop-up window containing the text of the associated note. | |
| Underline | 10 | An underline annotation appeara as an underlined text in a document. When opened, it displays a pop-up window containing the text of the associated note. | |
| Squiggly | 11 | A squiggly annotation appeara as a jagged underlined text in a document. When opened, it displays a pop-up window containing the text of the associated note. | |
| Strikeout | 12 | A strikeout annotation appeara as a stricked-out text in a document. When opened, it displays a pop-up window containing the text of the associated note. | |
| Stamp | 13 | A rubber stamp annotation displays text or graphics intended to look as if they were stamped on the page with a rubber stamp. When opened, it displays a pop-up window containing the text of the associated note. | |
| Caret | 14 | A caret annotation is a visual symbol that indicates the presence of text edits. | |
| Ink | 15 | An ink annotation represents a freehand “scribble” composed of one or more disjoint paths. When opened, it displays a pop-up window containing the text of the associated note. | |
| Popup | 16 | A pop-up annotation displays text in a pop-up window for entry and editing. It typically does not appear alone but is associated with a markup annotation, its parent annotation, and is used for editing the parent’s text. | |
| FileAttachment | 17 | A file attachment annotation contains a reference to a file, which typically is embedded in the PDF file. | |
| Sound | 18 | A sound annotation is analogous to a text annotation except that instead of a text note, it contains sound recorded from the computer’s microphone or imported from a file. When the annotation is activated, the sound is played. | |
| Movie | 19 | A movie annotation contains animated graphics and sound to be presented on the computer screen and through the speakers. When the annotation is activated, the movie is played. | |
| Screen | 20 | A screen annotation specifies a region of a page upon which media clips may be played. It also serves as an object from which actions can be triggered. | |
| Widget | 21 | A widget annotation is used by interactive forms to represent the appearance of a field and to manage user interactions. | |
| PrinterMark | 22 | A printer’s mark annotation represents a graphic symbol, such as a registration target, color bar, or cut mark, added to a page to assist production personnel in identifying components of a multiple-plate job and maintaining consistent output during production. | |
| TrapNet | 23 | A trap network annotation defines the trapping characteristics for a page of a PDF document. Trapping is the process of adding marks to a page along color boundaries to avoid unwanted visual artifacts resulting from misregistration of colorants when the page is printed. | |
| Watermark | 24 | A watermark annotation is used to represent graphics that are expected to be printed at a fixed size and position on a page, regardless of the dimensions of the printed page. | |
| ThreeD | 25 | 3D annotations are the means by which 3D artwork is represented in a PDF document. | |
