PDF Signing Tools Online

Sign PDF documents quickly and easily using pdfFiller's online tools, designed for small businesses and professionals.

What Are PDF Signing Tools?

PDF signing tools are software applications that allow users to sign PDF documents electronically. These tools provide significant benefits for small businesses, such as reducing the time and resources spent on printing and scanning documents. Unlike traditional methods, which often involve cumbersome paperwork and physical signatures, PDF signing tools enable users to sign documents digitally, making the process faster and more efficient.

How PDF Signing Tools Improve Workflow

PDF signing tools enhance document workflows by allowing users to sign documents instantly without the need for printing. This means that you can complete transactions and agreements from any device, whether you're in the office or on the go. The speed of signing is a major advantage, as it eliminates delays associated with traditional signing methods, ultimately improving overall productivity.

Three Methods to Sign PDF Documents

There are three primary methods to sign PDF documents using PDF signing tools: draw, type, and upload. Each method has its own legal validity and caters to different user preferences. Drawing your signature allows for a personal touch, typing offers a quick solution, and uploading an image provides a professional appearance. Understanding these methods helps users choose the best option for their needs.

Drawing Your Signature

  1. 1.
    Access the PDF signing tool and select the draw signature option.
  2. 2.
    Use a mouse or touchscreen to draw your signature on the document.
  3. 3.
    Adjust the size and position of your signature as needed.
  4. 4.
    Save the signature for future use if the tool allows.
  5. 5.
    Finalize the document by saving or sending it after signing.

Typing Your Signature

  1. 1.
    Select the type signature option in the PDF signing tool.
  2. 2.
    Choose a font style that resembles your handwriting.
  3. 3.
    Pick a color for your signature that stands out on the document.
  4. 4.

  5. 5.

Uploading an Image of Your Signature

Adding Initials to Your Documents

  5. 5.
    Save the document to maintain the added initials.

Customizing Your Signature Appearance

You can customize your signature's appearance by selecting different color and thickness options. Adjusting the size of your signature can also help it fit better within the document. These customization options allow you to create a signature that reflects your personal style while remaining professional.

Saving and Reusing Your Signature

To save your signature for future use, follow the steps provided by the PDF signing tool. Setting defaults for your signature can save time in future documents. Reusing your signature streamlines the signing process, making it easier to manage multiple documents efficiently.

Legal Validity of PDF Signatures

PDF signatures are legally valid when they comply with relevant laws and regulations. It's important to maintain an audit trail for signed documents, as this can serve as proof of consent. Understanding the verification process ensures that your signatures are recognized as legally binding in various contexts.

It can be great, but it's a little buggy at times. The signature feature often crashes the signer's device, whether mobile or desktop, and the API integration with Zapier is very finicky as well.
Chad D
I had a difficult time with it and it took a long time just to fill out passport forms for my wife and I. I just could not get the hang for it, but someone smarter than me and maybe younger, I am 72, will do much better with PDF filler.
Remmert K
Very easy to use That I could fill it in immediately and be able to upload it and save it somewhere else. Also that the formatting remained the same That I had to save it twice in order to get what I had wrote. I also hate that the text box does not stay within the area you type in.
Sheandra P.

Leann T.
So far everything seems to be working effectively. Only had one inconvenience and that was when I tried printing and I kept getting a black block on the signature panel.
Osaris C
I am a ******* Home Inspector and love PDFiller. I can do everything on my IPhone. I had a problem at first and had an online chat with ***, helped me fix a problem on a 4 point inspection and had it corrected in 15 mins. Once you learn your way around PDFiller it can save you lots of time.
