Annotations and drawing markup tools overview

Note: In Acrobat Reader, complete commenting tools are available only in PDFs that have commenting enabled.

You can use annotation and drawing markup tools to add comments. The commenting tools are made available in the secondary toolbar of the Comment feature. Comments are notes and drawings that communicate ideas or provide feedback for PDFs. You can type a text message using the Sticky Note tool. Alternatively, you can use a drawing tool to add a line, circle, or other shape and then type a message in the associated pop-up note. Text-editing tools let you add editing marks to indicate changes that you want in the source document. Most commenting and markup tools don’t appear in the toolbar until you enable the Commenting feature.

Note:

In Acrobat Pro, you can add tags to your comments so that readers with motion or vision limitations can read them using assistive technologies.

Show annotations and drawing markup tools

Annotations and markup tools don’t appear by default, except when you open a PDF in a managed review workflow.

  1. Choose Tools > Comment to open the Comment toolbar. The comments that you add to the document are displayed in the right pane.

  • To select the drawing markup tool, open the Comment toolbar and click the Drawing Tools icon . Select the desired tool from the Drawing Tools menu.
Note:

After you make an initial comment, the tool changes back to the Select tool so that you can move, resize, or edit your comment. (The Pencil and Highlight Text tools stay selected.)

Keep an annotation tool selected

You can add multiple comments without reselecting the tool.

  1. In the Comment toolbar, select the tool you want to use (but don’t use it yet).

  2. Click the Keep Tool Selected icon

Add a sticky note

Note:

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

The most common type of comment is the sticky note. A sticky note has a note icon that appears on the page and a pop-up note for your text message. You can add a sticky note anywhere on the page or in the document area.

Add a sticky note comment

  1. Select the Sticky Note tool  in the Comment toolbar, and click where you want to place the note.

  2. Type text in the pop-up note. You can also use the Select tool  to copy and paste text from a PDF into the note.

    Note:

    If you close the pop-up note, your text remains.

Edit a sticky note comment

  1. Click or double-click the note icon.
  2. Make changes, as needed:

    • To resize the pop-up note, drag the lower-left or lower-right corner.

    • To change the text formatting, click the Text Properties icon in the Comment toolbar, and select the text, and then select the property you want in the toolbar.

    Note:

    Use the Commenting panel in the Preferences dialog box to change the font size, default pop-up behavior, and other settings for creating and viewing comments

    After making the desired changes, click the close (X) button in the upper-right corner of the pop-up note, or click outside the pop-up note.

Copy partial text in a sticky note comment

  1. Click or double-click the note icon.

  2. Select the text, and then right-click and copy text.

Delete a sticky note

  1. Select the Sticky Note tool , the Hand tool , or the Select tool .

  2. Select the note icon, and press Delete.

    Alternatively, double-click the note icon and choose Delete from the Options menu of the pop-up note.

Add a text comment

Use the Add Text Comment tool to type text anywhere on the PDF page. The Add Text Comment tool is similar to the Add Text Box tool.

  1. Choose the Add Text Comment tool from the Comment toolbar.

  2. Click on the page to place the cursor

  3. To change the text formatting, click the Text Properties icon in the Comment toolbar, and select the text, and then select the property you want in the toolbar.

Change author name for comments

When you add a comment in a PDF file, by default your login name is used as author name for the comment. To change the author name, see change author name for comments.

Add a line, arrow, or shape

Note:

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

When selecting a drawing tool, consider the effect you want.

  1. Choose Tools > Comment. In the Comment toolbar, click Drawing Tools and select the drawing markup tool:

    • The Rectangle tool , the Oval tool , the Arrow tool , and the Line tool  let you create simple shapes.

    • The Cloud tool  and Polygon tool  create closed shapes with multiple segments. The Polygon Line tool  creates open shapes with multiple segments.

    • The Pencil tool  creates free-form drawings, and the Pencil Eraser tool  removes the pencil markups.

    Note:

    To specify the line width, color, and other properties before you draw, select the desired tool, and press Ctrl+E to open the properties toolbar. Set the desired options in the Properties toolbar.

  2. Draw in the PDF:

    • To create a cloud or polygon shape, click to create the start point, move the pointer, and click to create each segment. To finish drawing the shape, click the start point, or right-click and choose Complete from the menu. Double-click to end a polygon line.

    • To draw a line, arrow, or rectangle, either drag across the area where you want the markup to appear, or click twice: once to create the start point and once to create the end point.

    • To draw a square or circle, or to draw a line that’s horizontal, vertical, or at a 45° angle, press Shift while you draw.

    • To draw free-form lines using the Pencil tool , drag where you want to begin drawing. You can release the mouse button, move the pointer to a new location, and continue drawing. To erase parts of the drawing, select the Pencil Eraser tool  and drag across the areas of the drawing that you want to remove.

  3. To edit or resize the markup, select it and drag one of the handles to make your adjustments.
  4. To add a pop-up note to the markup, select the Hand tool, and double-click the markup.

  5. (Optional) Click the close button in the pop-up note. A note icon appears to the right of the markup to indicate the presence of text in the pop-up note.

    Note:

    To delete a drawing markup, select it and press Delete.

Also, you can edit PDFs with comments online. Our online PDF editor lets you add text, sticky notes, highlights, drawings, and more to PDFs with ease.

Group and ungroup markups

You can group two or more markups so that your comments function as a single comment. You might group markups temporarily to move them to a new location or to modify their properties rather than editing each one individually. Grouping also helps to distinguish your markups from other reviewers’ markups in a document review.

Note:

You cannot group text edit markups.

Group markups

  1. Using the Select tool or the Hand tool, select a markup.
  2. Ctrl-click/Command-click to select the markups you want to group.

  3. Right-click within the selection, and choose Group.

Ungroup markups

  1. Right-click the grouped selection, and choose Ungroup.

Add comments in a text box or callout

Note:

In Acrobat 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.

Text font and size are based on the system default settings.

Add comment in a text box or callout

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.

Add a text box

  1. Choose the Add Text Box tool from the Comment toolbar.

  2. Click in the PDF.

  3. Choose the Text Properties icon in the Comment toolbar, and then select the color, alignment, and font attributes for the text.

  4. Type the text.

    Text wraps automatically when it reaches the right edge of the box.

  5. (Optional) To make further changes to the text box:

    • Using the Select tool or the Text Box tool, click an edge of the text box to select it, and then drag a corner to resize it. Use the Properties toolbar to change the border and fill options.

    • Double-click the text box to edit the text or change the text attributes. Drag across text to select it, and then select options from the Properties toolbar.

  6. To delete the text box, select it, and then press Delete.

    Note:

    You can also paste a block of text by selecting and copying the text in any application, selecting the Hand tool in Acrobat, and choosing Edit > Paste.

Add a callout

  1. In the Comment toolbar, click Drawing Tools and choose the Add Text Callout tool.

  2. Click once to set the location of the end point, and click again to set the location of the text box.

  3. Choose the Text Properties icon in the Comment toolbar, and then select the color, alignment, and font attributes for the text.

  4. Type the text.

    Text wraps automatically when it reaches the right edge of the box.

  5. (Optional) To make further changes to the text box:

    • To resize the callout, select it and drag any of the handles that appear.

    • To move the text box, click inside the box and drag it.

    • To move the entire callout, click either the end-point line or an edge of the text box, and drag it.

    • To change the color, opacity, or line characteristics, use the Select tool to right-click the callout, choose Properties, and select the options you want.

Add an audio comment

Note:

In Acrobat 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 Record Audio Comment tool to add a prerecorded WAV or AIFF file as a comment or to record and place an audio comment in a document. Audio attachments appear in the Comments list and can be played back on any platform. However, the appropriate hardware and software for playing audio files must be installed.

Add comments in a file attachment

Note:

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

Use the Attach File tool to embed a file at a selected location in a PDF, so that the reader can open it for viewing. By adding attachments as a comment, you can reference longer documents that can’t easily be pasted into a pop-up note or text box. If you move the PDF to a new location, the embedded file automatically goes with it. To view an attachment, the reader must have an application installed that can open the attachment.

Note:

Be sure to use the Attach tool when attaching files for a document review. Document-level file attachments that you attach using the Attach A File tool from the Tools > Edit PDF > More menu aren’t tracked with other comments in a review workflow and may cause your attached comments to be lost.

  1. Choose the Attach File tool from the Comment toolbar.

  2. Click in the PDF where you want to place the attachment.

  3. Select the file that you want to attach, and then click Open. If you’re attaching a PDF, you can highlight areas of interest in the file using comments.

  4. In the File Attachment Properties dialog box, select the settings for the file icon that appears in the PDF.

    The comment attachment also appears in the Attachments tab (in the left navigation pane) with a page number indicating its location.

    Note:

    To delete the attachment, right-click the attached comment icon, and choose Delete.

Paste images as comments

Note:

In Acrobat 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 Paste Clipboard Image As Stamp Tool to add images to a PDF. You can copy most image formats from drawing and image-editing applications, such as Adobe Photoshop and Adobe Illustrator. If you want to add the image to PDFs repeatedly, create a custom stamp of the image.

Note:

The Paste Clipboard Image As Stamp Tool isn’t available until you copy an image.

  1. Copy an image by doing one of the following:

    • In Acrobat, choose Edit > Take A Snapshot , and select an image from a PDF. 

    • In another application, select an image and choose Edit > Copy.

  2. Open a PDF.

  3. Choose Tools > Comment. In the Comment toolbar, click the Add Stamp tool and select Paste Clipboard Image As Stamp Tool.

  4. Click in the PDF where you want the image to appear.
  5. Do any of the following:

    • To move the image, drag it.

    • To resize the image, select it and then drag one of its handles. Press the Shift key when resizing the image to maintain the original proportions.

    • To change the image properties, right-click it and choose Properties.

    • To delete the image, right-click it and choose Delete.

Commenting preferences

Commenting preferences affect both the appearance of and the way you view annotations and markups in PDFs.

Note:

A reviewer can place comments anywhere within the document frame. As a result, sometimes you need to scroll or zoom out to see comments that are located off the page.

In the Preferences dialog box under Categories, select Commenting.

Viewing comments

Font, Font Size

In Windows, you can determine the font and the size of text in pop-up notes. In Mac OS, you can select only Large, Medium, or Small settings for the font. This setting applies to all new and existing comments.

Pop-up Opacity

Determines the opacity of comment pop-up notes in values from 1 to 100. When a pop-up note is open but not selected, an opacity value of 100 makes the note opaque, while lower values make it more transparent.

Enable Text Indicators And Tooltips

Shows a tool tip when you place the pointer over a comment that includes a pop-up note. The tool tip contains the author name, comment status, and two lines of the text. Selected by default.

Print Notes And Pop-ups

Specifies that pop-up notes associated with comments, and icons for note, audio, and file attachments print exactly as they appear on the page.

Instead of selecting this option, you can print comment text in various layouts by choosing File > Print, and click Summarize Comments. For more details, refer the document to print comments.

Show Lines Connecting Comment Markups To Their Pop-ups On Mouse Rollover

When you place the pointer over a comment markup (such as a highlight or a note icon), the shaded connector line appears. Selected by default.

Ensure That Pop-ups Are Visible As The Document Is Scrolled

As you scroll a PDF, the pop-up notes on a given page shift to stay in view within the document pane. Selected by default.

When you place the pointer over a comment of any type, including drawing markups and stamps, the pop-up note opens.

Making comments

Always Use Log-in Name For Author Name

Determines which name appears in the pop-up note you create. If this option is selected, the Login Name in the Identity panel of the Preferences dialog box is used. If this option isn’t selected, the default name you specify for Author in a comment properties dialog box is used. Selected by default.

Create New Pop-ups Aligned To The Edge Of The Document

Aligns pop-up notes with the right side of the document window, regardless of where the comment markup (such as a note icon or highlighting comment) is added. If this option is deselected, the pop-up note appears next to the comment markup. Selected by default.

Allow nested reply to sticky notes (requires restart)

Allows reply to Sticky Notes with a single-thread experience. If this option is selected, each annotation appears like a conversation and all replies appear like a single-thread experience.

Enable Text Selection For Highlight, Strikethrough and Underline

Show checkbox

Displays the checkbox consistenty for all comments.
