Add Ink Signature in PDF Document

Quickly add your ink signature to a PDF document using pdfFiller.

What is the Ink Signature Tool?

The Ink Signature Tool in pdfFiller is designed for self-signing documents. It allows you to add an ink signature directly to your PDF without needing to send it out for signatures. The user-friendly interface makes it accessible for anyone, and there is no IT setup required. This tool simplifies the signing process, making it ideal for small and medium businesses that need a straightforward solution for digital signatures.

How Does This Tool Improve Document Workflows?

The ink signature tool significantly improves document workflows by reducing the time spent on signatures. It eliminates the need for printing and scanning, which can slow down the signing process. This tool supports remote work, making it perfect for small business needs where team members may not be in the same location. By streamlining the signing process, pdfFiller helps businesses operate more efficiently.

Three Ways to Create Your Signature

You can add an ink signature in three different ways using pdfFiller: draw, type, or upload an image. Each method is legally equivalent, allowing you to choose the one that suits you best. Drawing your signature gives a personal touch, typing offers a quick solution, and uploading an image provides convenience for those who already have a signature saved. This flexibility makes it suitable for various document types.

Adding Initials to Your Document

Customization options allow you to adjust the size and color of your initials. It's important to note that initials also hold legal validity, making this a quick process for users who need to sign documents efficiently.

Saving and Reusing Your Signatures

With pdfFiller, you can save your signatures to your account for future use. You can set a default signature, allowing for easy access when signing new documents. This feature streamlines the signing process, enabling you to work more efficiently without having to recreate your signature each time.

Legal Validity of Your Signature

Signatures created in pdfFiller comply with the ESIGN and UETA acts, ensuring their legal validity. Each signature is backed by a timestamped audit trail, providing verification of the signing process. Additionally, pdfFiller includes a badge that confirms the signature's legitimacy, making it a reliable choice for legally binding signatures.

Next Steps After Signing

After signing your document, you can easily share it with others. pdfFiller allows you to integrate signed documents into other workflows, enhancing your overall document management process. By going digital, you can enjoy the benefits of increased efficiency and reduced paperwork, which is essential for modern business practices.

How Does pdfFiller Compare?

pdfFiller offers a more user-friendly interface for small businesses compared to DocuSign, which may have more advanced features but at a higher cost. While Adobe Acrobat Sign may be better suited for larger enterprises with complex needs, pdfFiller provides a straightforward solution without requiring extensive training. Additionally, pdfFiller is more affordable and easier to use for everyday tasks than signNow, which may offer more integrations but lacks pdfFiller's extensive template library.
