How to create an Online Signature: 2025 Easy Guide

As more businesses and organizations adopt a digital approach to their workflow, it is becoming common to process paperwork online. Doing away with physical documents is not environmentally friendly, but it also increases document turnaround time and the overall efficiency of your workflow.

In this light, it's almost imperative that everyone knows how to write a signature online or use an electronic signature. If you are unsure how to create your own or use it, this article will walk you through the entire process. Let’s get started.

How to Write a Signature Online Using Fill

Fill has a wide array of fonts that you can choose from. Select one that slightly resembles your own handwriting.

Draw your signature

Simply use your mouse, trackpad, or stylus to draw your signature the way you would on paper. Make sure to check to see if it genuinely reflects your handwritten signature.

Upload your signature

Lastly, you can create an online signature by uploading a digital copy or image of your handwritten signature on Fill.

It is as straightforward as it sounds. The key here is to make sure that you use a black extra-thick broad pen to ensure it's legible and all the details are perfectly captured.

What is the differences between electronic signatures and handwritten signatures?

Both handwritten and electronic signatures confirm a signer’s identity and intent, but the way they are created, stored, and verified is very different. Understanding these differences helps you decide when to use a traditional signature versus an online one.

Handwritten signatures are traditional but limited by time, location, and security risks. Electronic signatures, on the other hand, provide a faster, safer, and legally recognized way to sign documents online—making them the smarter choice for modern workflows.

The Advantages of Signing Documents Online

Adopting electronic signatures goes far beyond just “going paperless.” It introduces real, measurable benefits that make document handling faster, safer, and more efficient. Here’s a closer look at why online signing has become the standard for modern businesses and individuals:

1. Time Savings and Speed

Traditional signing often involves printing, mailing, scanning, or arranging in-person meetings. Online signatures remove these steps entirely. With just a few clicks, contracts can be signed and finalized within minutes, drastically reducing turnaround times that used to take days or even weeks. This accelerated pace keeps projects moving forward without unnecessary delays.

2. Convenience and Accessibility

Whether you’re at the office, working from home, or traveling, electronic signatures let you sign documents anytime, anywhere. Most platforms work seamlessly on desktops, tablets, and smartphones. This flexibility is especially valuable in today’s hybrid and remote work environments, where team members and clients may be spread across different time zones.

3. Enhanced Security and Fraud Prevention

Handwritten signatures can be forged or altered, but digital signatures are protected with encryption and cryptographic algorithms. This technology verifies the signer’s identity, locks the document against tampering, and provides traceable records. As a result, eSignatures are often considered more secure than traditional pen-and-paper methods.

4. Automated Workflow and Efficiency

Modern eSignature platforms don’t just capture signatures—they streamline the entire process. Features like automated reminders, progress tracking, and centralized dashboards ensure no document is overlooked. By eliminating repetitive manual tasks, teams gain efficiency and maintain clear oversight of document workflows.

5. Cost Savings and Environmental Impact

Printing, mailing, and storing paper documents isn’t just slow—it’s expensive. Online signatures cut these costs dramatically while also reducing paper usage. For organizations committed to sustainability, this shift supports eco-friendly practices by lowering their environmental footprint.

6. Legal Validity and Compliance

Electronic signatures are legally recognized in many jurisdictions under regulations such as the ESIGN Act (U.S.) and eIDAS (EU). Most reputable eSignature solutions also provide audit trails and tamper-evident seals, making signed documents enforceable in court and compliant with global standards.

7. Better Record Management and Auditability

Signed documents no longer need to sit in filing cabinets or be manually tracked. Instead, they’re securely stored in the cloud with searchable audit trails. This makes it easier to retrieve, verify, and manage documents for compliance, internal reviews, or legal requirements.

Use Cases of Writing Signatures Online

The true value of learning how to write a signature online lies in its wide range of applications. From business to education, eSignatures streamline processes, save time, and enhance security across different scenarios. Let’s explore some of the most common use cases in detail:

Business Contracts and Agreements

Electronic signatures have become indispensable in modern business transactions. Whether it’s a sales contract, a vendor agreement, or a partnership deal, online signing eliminates delays caused by mailing or in-person meetings. Teams can finalize agreements instantly, ensuring faster deal cycles and uninterrupted workflows. With proper encryption and audit trails, businesses can also maintain compliance while keeping records organized and accessible.

Human Resources and Employee Onboarding

HR teams deal with a significant volume of documents—from offer letters and NDAs to performance reviews and exit forms. Online signatures simplify this process by allowing employees and employers to complete paperwork remotely. This not only supports hybrid and remote work models but also creates a smoother onboarding experience for new hires. Every signature is securely stored and easily retrievable for compliance and record-keeping.

Legal and Compliance Documents

In legal and compliance-heavy industries, security and enforceability are paramount. Electronic signatures ensure contracts, compliance reports, and binding agreements meet global standards such as the ESIGN Act or eIDAS. They also provide tamper-evident features and audit trails, which are critical in case of disputes. By reducing paperwork and manual errors, legal teams can focus more on advising and less on chasing documents.

Healthcare and Patient Forms

Hospitals, clinics, and healthcare providers rely on signed consent forms, insurance paperwork, and intake documents. Moving these processes online speeds up administrative tasks and reduces waiting times for patients. Digital signatures also minimize the risk of misplaced records while complying with regulations like HIPAA, ensuring both efficiency and data security.

Education and Administrative Approvals

From enrollment forms to permission slips, schools and universities benefit greatly from electronic signatures. Parents and students no longer need to print, sign, and return physical forms. Instead, signatures can be completed online, making administrative approvals quicker and more efficient. This approach reduces paperwork burdens for institutions and provides a seamless experience for families.

By covering these diverse use cases, it’s clear that online signatures are more than a convenience—they’re a practical necessity for organizations looking to stay efficient, secure, and future-ready.

How to Safely Sign Documents Online

One of the most pressing issues surrounding the modern document signing process and solutions is the safety and security of your data. Many have become vulnerable to data breaches and information theft in recent years, and they are serious risks that you just can’t take lightly.

Naturally, when you’re relatively new at signing documents online and still learning to write a signature electronically, you are more vulnerable to these risks. But do not let those risks stop you from digitalizing your processes. Here are some easy tips to help you keep your paperwork safe:

1. Use reliable electronic signature applications that use high-level encryption. There are plenty of them at your disposal, so when you choose which is the best for you, always ensure that your choice uses robust security and safety measures.
2. If you must sign and send a highly confidential document over the internet, save it in a format that’s not easy to manipulate or tamper with. Set your documents to PDF. You can also set a password so unauthorized individuals cannot easily access the contents of your files.
3. Knowing how to write a signature online protects your document from malicious threats and possible breaches. Create a unique electronic signature. Of course, you can digitally sign if you want something that offers even higher security measures.
