What is an electronic signature?

An electronic signature (or eSignature) is a legally recognized way to show a person’s intent to agree to or approve an electronic document. Depending on the signing workflow, an electronic signature may consist of a typed name, a drawn signature, clicking an Accept button, or another electronic action associated with the signer.

Unlike traditional handwritten signatures, electronic signatures allow individuals and businesses to sign PDF online from virtually anywhere while maintaining a verifiable record of the signing process.

It’s important to distinguish electronic signatures from digital signatures. While the terms are often used interchangeably, a digital signature is a specific type of electronic signature that uses cryptographic technology and digital certificates to verify signer identity and detect document tampering.

In the United States, electronic signatures are generally recognized under the Electronic Signatures in Global and National Commerce (ESIGN) Act and the Uniform Electronic Transactions Act (UETA). In the European Union, electronic signatures are governed by the eIDAS Regulation, which defines Simple Electronic Signatures (SES), Advanced Electronic Signatures (AES), and Qualified Electronic Signatures (QES).

The purpose and benefits of electronic signatures

Electronic signatures are used to sign documents online, eliminating the need for printing, scanning, mailing, and storing paper copies. They support a wide variety of business processes, including contracts, onboarding documents, purchase agreements, tax forms, healthcare paperwork, financial documents, and internal approvals.

As organizations continue adopting digital-first workflows, eSignature platforms have evolved beyond simple signing tools into complete document workflow solutions that help automate approvals, improve collaboration, and reduce administrative work.

1. Faster document turnaround

Instead of waiting days for documents to be printed, mailed, or scanned back, recipients can review and sign PDF online within minutes from a desktop or mobile device. Automated reminders and signing workflows help reduce delays.

2. Improved security

Electronic signature platforms help protect documents through encryption, audit trails, signer authentication, permission controls, and tamper-evident document history, providing greater visibility than traditional paper-based processes.

3. Lower operating costs

Organizations can significantly reduce expenses associated with printing, postage, physical storage, and manual document handling while minimizing administrative overhead.

4. Better customer and employee experience

Modern eSignature solutions enable customers and employees to complete documents from virtually anywhere without downloading specialized software, creating a faster and more convenient experience.

5. Global collaboration

Teams, customers, vendors, and partners can review and sign documents across countries and time zones, helping organizations accelerate international business operations.

6. Compliance and audit readiness

Leading eSignature platforms generate detailed audit trails that record key signing events, timestamps, recipient actions, and document history. These records help organizations demonstrate compliance and support internal governance requirements.

Types of electronic signatures

Electronic signatures come in various forms, each offering a different balance of convenience, identity verification, and legal assurance.

Simple Electronic Signature (SES)

A Simple Electronic Signature (SES) is the most commonly used type of eSignature. It can include a typed name, a drawn signature, clicking an “I Agree” button, or another electronic action that demonstrates a person’s intent to sign. SES is suitable for many everyday business documents, including sales agreements, NDAs, HR forms, and internal approvals.

Advanced Electronic Signature (AES)

An Advanced Electronic Signature (AES) provides stronger identity verification and is uniquely linked to the signer. Depending on the platform and jurisdiction, it may incorporate multi-factor authentication, biometric verification, or digital certificates. AES is commonly used when organizations require greater confidence in signer identity.

Qualified Electronic Signature (QES)

A Qualified Electronic Signature (QES) is the highest level of electronic signature recognized under the EU’s eIDAS Regulation. It requires identity verification by a Qualified Trust Service Provider (QTSP) and uses a qualified digital certificate. Within the European Union, a QES carries legal effect equivalent to a handwritten signature in many regulated scenarios.

Choosing the appropriate signature type depends on your organization’s legal requirements, industry regulations, and the level of identity assurance needed for each transaction.

How to create an electronic signature

Whether you’re signing a contract yourself or preparing documents for customers, creating an electronic signature takes only a few minutes with SignNow. The platform works in any modern browser and is also available on mobile devices, allowing you to e-sign PDF documents from virtually anywhere.

SignNow supports commonly used document formats, including PDF, Microsoft Word (DOC/DOCX), PowerPoint (PPT/PPTX), Excel (XLS/XLSX), and popular image formats such as JPG and PNG, making it easy to prepare documents without converting files first.

Follow these steps to create your electronic signature in SignNow.

1. Upload your document

Log in to your existing SignNow account or start a free trial. Upload a document from your computer or import one from supported cloud storage services. You can also start from a reusable template if you frequently send the same document.

From your dashboard, you can:

• open an existing document;
• upload a new file;
• use a saved template for recurring workflows.

2. Prepare your document

Select Prepare & Send to open the document editor.

From here, you can:

• add fillable fields;
• insert signature, initials, date, text, checkbox, and dropdown fields;
• edit document content where supported;
• assign fields to individual recipients;
• set required fields before sending.

If multiple people need to sign, add each recipient and assign only the fields relevant to them. This helps reduce errors and keeps the signing experience simple.

3. Create your signature

SignNow lets you create a signature in several ways.

Type your name

Type your full name and choose from available handwritten-style fonts.

Draw your signature

Draw your signature using a mouse, trackpad, touchscreen, or stylus.

Upload an image

Upload an image of your handwritten signature in PNG, JPG, or JPEG format and position it where needed.

Once created, your signature is securely saved to your account so it can be reused in future documents without recreating it each time.

4. Configure recipients and authentication

After assigning signature fields, configure recipient settings before sending the document.

Depending on your workflow, you can:

• require recipients to sign in a specific order;
• add expiration dates;
• schedule automatic reminders;
• apply recipient authentication methods, such as password or SMS authentication, where available;
• prevent recipients from forwarding documents.

These options help organizations maintain secure and organized approval workflows, especially when multiple stakeholders are involved.

5. Send and track your document

Once everything is ready:

• click Send Invitation;
• recipients receive an email invitation;
• they review the document;
• consent to electronic business where required;
• complete the signature.

After sending, you can monitor document status from the SignNow dashboard. Real-time status updates show whether a document has been viewed, signed, completed, or is still awaiting action.

What makes SignNow safe and secure?

Security is one of the most important considerations when choosing an eSignature platform. Organizations routinely use SignNow to process contracts, HR paperwork, healthcare documents, financial forms, and other sensitive records that require strong data protection.

SignNow includes multiple layers of security designed to help protect documents throughout their lifecycle. Depending on your subscription and workflow, these protections may include encryption, authentication, audit logging, secure cloud infrastructure, and compliance with widely recognized industry standards.

Document encryption

Documents are protected using industry-standard encryption for both stored files and data transmitted between users and the platform, helping reduce the risk of unauthorized access.

Comprehensive audit trails

Every completed document includes a detailed audit trail and document history.

The audit log records document activity such as recipient actions, timestamps, IP addresses, email addresses, authentication events, and document completion history. These records help organizations demonstrate document integrity and support compliance requirements.

Authentication options

Organizations can strengthen signer verification by requiring additional authentication methods before recipients access a document. Available options may include password protection and SMS authentication, depending on the workflow and subscription.

Business continuity

Enterprise-grade document platforms maintain disaster recovery and business continuity procedures designed to minimize service interruptions and protect customer data.

Compliance

SignNow supports organizations operating in regulated industries by offering features designed to help customers meet compliance obligations. Depending on the use case and account configuration, the platform supports standards and regulations such as:

• ESIGN Act
• UETA
• HIPAA (available with appropriate agreements and configuration)
• SOC 2 Type II
• PCI DSS
• GDPR
• FDA 21 CFR Part 11 (for applicable workflows)

Because regulatory requirements vary by organization and jurisdiction, businesses should verify that their selected subscription and configuration meet their specific compliance obligations before deploying electronic signature workflows.

How to electronically sign a PDF document with SignNow

Whether you’re signing a contract yourself or requesting signatures from others, SignNow lets you sign PDF online from any modern browser or mobile device. The process takes just a few minutes and requires no software installation.

Step 1. Upload your PDF

Sign in to your SignNow account or start a free trial. Upload a PDF from your computer or import one from a supported cloud storage provider.

SignNow also supports Microsoft Office documents and common image formats, automatically preparing them for electronic signatures where applicable.

Step 2. Prepare the document

Click Prepare & Send to open the editor.

Here you can:

• add signature, initials, date, text, and checkbox fields
• assign fields to each signer
• include optional instructions for recipients
• review the document before sending

If you’re the only signer, simply assign the signature field to yourself. If multiple people need to sign, assign fields to each recipient before continuing.

Step 3. Configure recipients

Add each recipient’s email address and determine how the signing process should work.

Depending on your workflow, you can:

• define a sequential signing order
• send documents to everyone simultaneously
• schedule reminders
• set document expiration dates
• apply recipient authentication for additional security where available

These settings help keep document approvals organized, especially for contracts that require signatures from multiple stakeholders.

Step 4. Send the signature request

Click Send Invitation.

Recipients receive an email with a secure link to review and sign the document.

Before signing, recipients may be asked to consent to conducting business electronically and complete any required authentication steps, depending on the sender’s configuration.

Step 5. Sign the document

Open the document.

Click the highlighted signature field.

Choose your saved signature or create one by typing, drawing, or uploading an image if you haven’t already done so.

Click Sign, then Finish.

Once completed, you can download the signed PDF, share it with other recipients, or access it later from your SignNow account.

Step 6. Track document status

After sending the document, you can monitor its progress directly from the SignNow dashboard.

You’ll be able to see whether the document has:

• been sent
• viewed
• signed
• completed
• or is still awaiting signatures

Real-time tracking helps eliminate manual follow-ups and gives document owners visibility into every stage of the signing process.

If you frequently send contracts, you can also learn how to sign contracts online for multi-party approval workflows.

How to change the signing order in SignNow

Many business documents require signatures in a specific sequence—for example, an employee, manager, and HR representative may all need to sign before a document is finalized. SignNow lets you define that order before sending the document.

To create a sequential workflow:

1. Add all recipients
2. Enable the option that delivers the document in signing order (if available for your workflow)
3. Assign each signer their position in the sequence
4. Save your changes

Recipients will receive the document only after the previous signer has completed their required fields, helping maintain approval workflows and reduce signing errors.

If your workflow doesn’t require a specific sequence, you can send the document to all recipients simultaneously so everyone can sign independently.
