Instructions and Help about Switch from Nitro to pdfFiller for a Insert Line In PDF Document Online Solution For Free

Did you ever need to insert lines in PDF documents in order to underline or cross something out, or to show graphically connections between different parts of the document?

In the past, you probably had to print the document, make your drawings, and either scan it 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 insert straight lines in PDF documents. You can simply use pdfFiller!

To get started, upload a document to your account and open it in the editor. To insert 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 inserting 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 click on it and then click the trash can icon that will appear.

PDF Filler service and support! The actual service platform is fantastic, but their customer support is also top notch. One of their service agents, Kara, took care of an issue I was having within moments, and all done in an incredibly friendly and professional manner. Kudos to Kara! ;-)

Pedif Griffin It's pretty nice for a PDF-filling application. Wish I could do a reasonable one-time purchase instead of having to pay monthly, though.
