What Is a Digital Signature?

A digital signature is a specialized form of electronic signature designed for high security and legal validity. Unlike simpler electronic signatures—such as a typed name or drawn mark—a digital signature relies on public key infrastructure (PKI) and a digital certificate from a trusted Certificate Authority (CA) to confirm the signer’s identity and the document’s integrity.

The process is straightforward yet robust. When you sign, your private key encrypts a unique signature tied to the document. The recipient then uses your public key, linked to the certificate, to decrypt and verify it. This cryptographic method ensures the document remains unchanged since signing, making it tamper-evident and trustworthy.

Digital signatures shine in scenarios demanding strong security, like legal contracts, financial agreements, or encrypted PDFs. Their cryptographic backbone not only proves authenticity but also meets strict legal standards, such as the EU’s eIDAS regulation or the U.S. ESIGN Act, making them critical for high-stakes use.

As for pdfFiller, it excels at electronic signatures—letting you draw, type, or upload a signature—but it doesn’t support true digital signatures with PKI or certificates. To add that layer of security, you can prepare a document in pdfFiller, then use a third-party tools with a CA-issued certificate. This combo leverages pdfFiller’s convenience while meeting advanced security needs.

Why Use pdfFiller to Work with Digital Signatures?

Business users and individuals choose pdfFiller for its simplicity and robust features. While pdfFiller itself does not create digital signatures, it allows you to collaborate with third-party tools to digitally sign documents and PDF files online, eliminating the need for paper documents. The platform makes it easy to prepare your documents for signing by enabling you to edit, format, and share files seamlessly. You can then use integrated third-party solutions to securely add digital signatures. Plus, pdfFiller's focus on data security ensures your files remain protected throughout the process.

How to Create a Digital Signature in pdfFiller

Though pdfFiller doesn’t offer native digital signature functionality, it is a powerful tool for creating electronic signatures that are also legally valid. To get started with electronic signing, sign up for a pdfFiller account if you haven’t already—it’s fast and includes a free tier for basic use. Once logged in, you can upload your PDF file and begin the process. The platform’s user-friendly interface makes it accessible, even for those with little technical experience. If you need a true digital signature with certificates, you’ll pair pdfFiller with third-party tools, and we’ll cover that too.

Creating electronic signatures with pdfFiller is simple and efficient, tailored for everyday needs. While digital signatures with cryptographic security aren’t available in pdfFiller, you can use it as a starting point before adding advanced security elsewhere. Here’s how to proceed:

1. Upload Your Document

Open the PDF in pdfFiller via your browser or app, then upload the PDF document you want to sign. Drag and drop the file or click “Choose File” to select it from your computer or mobile device. The process is fast and works seamlessly across platforms.

2. Access the Signature Tool

Click the “Sign” button in pdfFiller’s toolbar. This opens options to craft an electronic signature—note that pdfFiller doesn’t include cryptographic digital signature features, but it’s ideal for standard signing needs.

3. Choose Your Method

pdfFiller provides three ways to create an electronic signature: type, draw, or upload. Select the method that suits you—each generates a signature image for reuse, though it’s not a certificate-based digital signature.

• Typing Your Signature
  

For speed, choose “Type” in the signature tool. Enter your name, and pdfFiller transforms it into a professional-looking signature with a stylized font. Adjust its size and position on the document, then save it as a quick, efficient signature option.

• Drawing Your Own Signature
  

For a personal touch, select “Draw.” Use your mouse, stylus, or touchscreen to sketch your handwritten signature directly in pdfFiller. The tool smooths out shaky lines for a polished result, which you can save for future use across documents.

• Uploading a Signature Image
  

If you have a handwritten signature saved as an image (e.g., PNG or JPEG), pick “Upload.” Scan your signature, upload the file, and place it on the PDF file. It’s a straightforward way to digitize your real handwriting without redrawing.

4. Adding a Digital Certificate for Security

pdfFiller doesn’t support digital certificates or public key infrastructure for true digital signatures, which ensure authenticity and tamper-proofing. For that, export your signed PDF from pdfFiller and use third-party toolsю Obtain a certificate from a Certificate Authority, import it into the third-party software, and apply a digital signature for legally binding, high-security needs.

5. Placing Your Signature on the PDF Document

Once your electronic signature is ready in pdfFiller, click to place it on the signature line or signature box. Drag it to the right spot, resize as needed, and confirm. Add initials or multiple signatures if the document requires extra approvals from parties involved.

6. Signing Many Documents at Once

For bulk signing, pdfFiller simplifies the task. Upload multiple PDF documents, select your saved electronic signature, and apply it to all files with one click. It’s a time-saver for businesses managing sales contracts or electronic records, though adding digital signatures would require batch processing in a separate tool like.

7. Saving and Sharing Your Signed PDF

After signing, save your PDF to pdfFiller’s cloud, download it to your device, or share it via email or a link directly from the platform. Files remain accessible for future use, but for court-admissible digital signatures, ensure you’ve added a certificate using a third-party tool.
