How to Write Notes on PDF Files

Create notes and editorial comments in Adobe portable document format files by using the Sticky Note utility in Adobe Acrobat or Adobe Reader 8. This tool allows users to pin comments to a PDF similar to a sticky note or written edit on a paper document. File creators can use the utility any time they wish. In a workflow situation with many recipients or users, the file creator may elect to enable or disable Sticky Notes. Users can only post comments to files with comments enabled.

You can make Sticky Note comments in PDF files.

Step

Open the PDF with either Adobe Reader 8 or Adobe Acrobat.

Step

Select “Document” in the program menu bar. Select “Comments” in the drop-down menu and then select “Add Sticky Note.” A yellow sticky note icon will appear in the document main window.

Step

Use your pointer to drag the sticky note icon where you want it in the document. You can do this many times.

Step

Click the "Sticky Note" icon. A text balloon will open. Write your note in the text balloon. The balloon will expand as you type, but you can also drag the balloon borders to enlarge or shrink the text window. Press "Enter" when finished.

Step

Double-click the balloon if you wish to modify the note again, or use your pointer to drag the icon to a new location. A balloon tether leading back to the icon will follow the open note wherever you drag it. To close the window, click the "X" in the right corner of the balloon box.
