Digitally Sign a PDF in Less Than a Minute

Anyone can sign a document in a few simple steps:

01
Begin by uploading a file and opening it in the editor.
02
Insert all necessary information in the sample.
03
Add a signature or initials field to your document. To do that, open the “Add Fillable Fields” tool on the left-side. Select the necessary field and place it on the page.
04
Click on the highlighted signature box. A pop-up window will appear next.
05
Select your method for signing a PDF. There are several ways to do so:
  • Type your full name on the keyboard, your handwritten initials will appear on the screen. It is the easiest way to create a digital signature.
06
Draw your autograph with a mouse or touchpad. It will take a little more time, but the autograph will look natural.
07
Upload a photo of a signature written on paper or capture it with your camera.
08
Draw an autograph with your smartphone’s screen. Opt to use a scan of a QR code or send a link via SMS or email.
09
Finally, your legally binding signature will appear in the cell. Note that the system automatically saves every signature you create, and you can reuse them an unlimited number of times. Next time you fill and sign PDF document, you don’t need to create a new signature, but select one of the existing ones and add it to your template.
10
Save a template and download it to your computer or store it in your personal account.

One more useful feature you can work with is the signature request. Those who need to collect autographs for their samples can do so via email. The best part is that even unsubscribed users can place their initials in the sample following the link you send them. Once a person signs a document, a notification will be sent to you.

On a day that I was going to really need my PDFfiller, the service was interrupted. My auto renewal had frozen up somehow and I couldn't access the service I was paying for. I immediately contacted customer service and notified them of the issue. To say that they went right into action to fix my problem would be an understatement. PDFfiller - you're service is great. You're customer service is AWESOME. Thank you for not only addressing my issue quickly and efficiently but for going above and beyond to make up for the inconvenience to me.
