Sometimes, when completing a PDF form we don’t know the exact answer to a particular question or need feedback from the document recipient. In situations like this, you can add comments to PDF documents online. In the past, you probably had to print the form and write your comments on the margins of the paper copy. Depending on your handwriting, the form might not have been very tidy and pleasant to look at. Now there is a far easier way to comment PDFs online. PDFfiller's simple but powerful document editor allows you to add text boxes with comments and remove them when they are no longer needed. To get started, you can upload a form to your account or open a document that’s already there.

Select the Text Box tool

in the main toolbar, click where you want to place the box and type your comment. To resize the text box, drag its corners or edges. Change the font and its size by choosing from the drop-down lists.

You can underline, italicize or make your text bold using the respective tools.

Change position of the text using the vertical and horizontal alignment tools

To change the color of your text, click the text color box and select the color you want.
