Did you ever need to underline or cross out text in PDF documents?

In the past, you probably had to print the document, underline words or phrases with a pen, and either scan the document or send a hard copy to wherever it needed to go. Besides needing a printer and a scanner, the process probably took you far too much time to complete.

Now there is a far easier way to underline text in PDF documents. You can simply use pdfFiller!

To get started, upload a document to your account and open it in the editor. To draw a line, click the Line icon in the main toolbar. The line toolbar will appear under the editing tools. Click where you want to create the start point and drag to where you want to create the end point, release the mouse button and click OK.

To change the line’s color, click on the black square and choose the color you want. Use the slider before or after drawing a line to change its thickness. You can change the position of the line ends by dragging them. Finally, you can always delete any line you've drawn, just select it and click the trash can icon that will appear.

The ease and operation was fantastic. I get confused very easily with all the new technology. With PDFFILLER I was able start at file I found in the browser and fax it, import a file and email it without any trouble. I will be using this a lot.

Great tool Easy to use and has functionality I need. Think there is some maximum number of pages you can convert at one time so have to break it up.
