Add Comments In a PDF Document Online

Markups are a very handy and powerful annotation tool. You can use them, for instance, when you edit a PDF document together with your colleagues.

Image

To insert a markup, choose the Arrow icon in the main toolbar. The markup toolbar will appear under the editing tools. Select the markup 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 press OK. To change the markup’s color, click on the color square and choose the color from the drop-down. Use the slider to change the markup’s thickness.

Image

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

Great Product! I love this software; it has been invaluable. I have used it to fill out job applications, insurance, medical & school documents. I'll continue to use it. It is very easy to upload documents to this software. Editing is user-friendly even for those not technically savvy. I like that I have many options in saving or exporting my finished document. Also, I like that my previous documents are saved because there has been more than once that a document has been lost or needed again. I have been saved by the fact that PDF Filler has the previously used document saved. I have not found anything I really dislike about this software. I'll be honest in that I'm not crazy about the price but I have found this software so helpful I have been using it for over two years now. I've recommended it to several people. I did not rate the customer service because I have never used it. I guess the fact that I've been using this for over two years & never had a customer service issue speaks for itself.
