How to Add Comments in PDF

Comments are a very handy and powerful annotation tool. For instance, you can use them when you edit a PDF document with your colleagues.

To add a comment, click the Arrow icon in the main toolbar. The comment toolbar will appear under the editing tools. Select the comment you need, then click anywhere to create the start point and drag to where you want to create the end point. Release the mouse button and select OK. To change the comment’s color, click on the color square and choose the color from the drop-down. Use the slider to change the comment’s thickness.

To reverse a comment, select it and click the icon of the comment with the opposite direction. To convert a simple comment into a two-headed comment, click the icon of the two-headed arrow. To change position of the start or end point, just drag it. To delete the comment, press the trash can icon above it.

How to send a fillable document that can be returned in a completed state I am new to using the pdf filler application in my business. When I sent my first document out, my client had a problem returning the filled out document. I used the chat feature to resolve my problem and received excellent help from Sam, who answered my questions and provided me with great resources.
