Electronic Signature vs Digital Signature: What's the Difference?

Understanding the distinction between electronic signatures and digital signatures is crucial for choosing the right solution for your needs. While both allow you to sign documents electronically, they differ significantly in their technology and security levels.

What is an Electronic Signature (E-Signature)?

An electronic signature is any electronic indication of a person's intent to agree to the contents of a document. This can be a typed name, a scanned image of a handwritten signature, a click on an "I Accept" button, or a signature drawn with a mouse or touchscreen. E-signatures are legally binding under the ESIGN Act and are perfect for everyday business documents.

Our PDF signature tool creates simple electronic signatures that include:

  • Visual signature image on your PDF
  • Timestamp of when the document was signed
  • Signer's name and email address
  • IP address for identity verification
  • Signature reason (approval, agreement, etc.)

What is a Digital Signature?

A digital signature is a more advanced form of electronic signature that uses cryptographic technology and digital certificates issued by trusted Certificate Authorities (CAs). Digital signatures provide:

  • Mathematical proof that the document hasn't been altered
  • Strong identity verification through PKI (Public Key Infrastructure)
  • Non-repudiation - the signer cannot deny signing
  • Tamper detection - any changes invalidate the signature

When to Use Each Type

Use electronic signatures for:

  • Employment contracts and offer letters
  • Sales agreements and purchase orders
  • NDAs and confidentiality agreements
  • Service contracts and vendor agreements
  • Rental leases and tenant forms
  • Consent forms and approvals
  • Internal business documents

Use digital signatures for:

  • Government submissions and regulatory filings
  • Financial transactions and loan documents
  • Healthcare records (HIPAA compliance)
  • Legal court documents
  • High-value commercial contracts
  • Documents requiring long-term validation

Legal Validity: ESIGN Act & eIDAS Compliance

In the United States, the ESIGN Act (Electronic Signatures in Global and National Commerce Act) of 2000 grants electronic signatures the same legal status as handwritten signatures for most business and consumer transactions. The law requires:

  • Clear intent to sign (clicking "Sign" button)
  • Consent to do business electronically
  • Association of signature with the specific record
  • Retention of electronic records
  • Ability for all parties to access and retain copies

Our PDF signature tool automatically fulfills all ESIGN Act requirements by embedding metadata and creating a complete audit trail with each signature.

In the European Union, eIDAS (electronic IDentification, Authentication and trust Services) regulation establishes three levels of electronic signatures:

  • Simple Electronic Signature (SES): Basic e-signature with signature data - our tool creates these
  • Advanced Electronic Signature (AES): Uniquely linked to signatory with identity verification
  • Qualified Electronic Signature (QES): Highest level, equivalent to handwritten signature in all EU countries

Best Practices for Electronic Signatures

Creating a Professional Signature

Your electronic signature represents you in legal documents. Follow these tips for professional-looking signatures:

  • Handwritten image: Sign on white paper with black ink, photograph or scan clearly, crop tightly around signature
  • Typed signature: Use your full legal name for formal documents, first name only for informal approvals
  • Drawn signature: Practice on scratch paper first, use smooth strokes, keep it legible
  • Consistency: Use the same signature style across all business documents for recognition

Positioning Your Signature

Proper signature placement ensures documents look professional and clearly indicate your agreement:

  • Standard contracts: Bottom-right corner on signature line if present
  • Multi-page agreements: Last page near signature block or designated fields
  • Approval stamps: Top-right corner with date for internal documents
  • Witness signatures: Below primary signature or in designated witness section
  • Size matters: Keep signatures proportional - not too large or too small

Legal Considerations

Ensure your e-signatures maintain legal validity:

  • Intent to sign: Always review documents fully before adding your signature
  • Capacity to sign: Ensure you have authority to bind yourself or your organization
  • Record keeping: Download and save signed PDFs immediately for your records
  • Metadata preservation: Our tool embeds signing metadata for audit trails
  • Document integrity: Don't modify PDFs after signing - creates new unsigned version
  • Confidentiality: Only sign documents on secure devices with trusted internet connections

Security Tips

Protect your signature and signed documents:

  • Signature images: Store signature images securely, never share publicly
  • Device security: Use updated antivirus and sign from trusted devices
  • Network safety: Avoid public WiFi when signing sensitive documents
  • Email caution: Verify sender identity before signing emailed documents
  • Backup copies: Save signed PDFs to secure cloud storage or encrypted drives
  • Regular review: Check your signed documents list periodically for unauthorized use

Business Workflow Integration

Streamline your document signing process:

  • Template creation: Save frequently-signed document templates for quick reuse
  • Batch signing: Process multiple similar documents in sequence
  • Mobile signing: Sign urgent documents from your phone or tablet
  • Team coordination: Establish signing authority levels and approval workflows
  • Archive system: Maintain organized folders for signed contracts by category and date

Frequently Asked Questions

How can I sign a PDF online for free?

Upload your PDF to our free online signature tool, choose how to create your signature (upload image, type, or draw), position it on your document, enter your details, and download the signed PDF. No registration required and completely free.

Are electronic signatures on PDF documents legally valid?

Yes, electronic signatures are legally valid in the US under the ESIGN Act (2000) and in the EU under eIDAS regulations. Our tool creates compliant e-signatures with proper metadata tracking including timestamp, signer name, email, and IP address for legal validity.

What is the difference between electronic signature and digital signature?

Electronic signatures (e-signatures) are any electronic indication of agreement, like typed names or drawn signatures. Digital signatures use cryptographic certificates for advanced authentication. E-signatures are legally valid for most contracts, while digital signatures provide higher security for sensitive documents.

Can I sign PDF documents on my mobile phone?

Yes, our PDF signature tool works perfectly on mobile devices. You can upload PDFs, draw signatures with your finger, type your name, or upload signature images from your phone's camera or gallery. The mobile interface is optimized for touchscreen signing.

How do I create a signature to upload?

Sign your name on white paper with a black pen, take a clear photo, and upload it. Alternatively, use our built-in signature drawing tool to create a signature with your mouse or touchscreen. You can also simply type your name and we'll convert it to a signature style.

Is my PDF document secure when signing online?

Yes, all files are encrypted with SSL during upload and processing. Your PDFs are automatically deleted from our servers within 1 hour of signing. We never store, share, or access your documents. All processing happens securely in the cloud with enterprise-grade encryption.

Can I add multiple signatures to one PDF?

Currently, our tool adds one signature per session. To add multiple signatures, download the signed PDF and re-upload it to add another signature. This approach maintains clean audit trails with separate timestamps for each signature.

Do signed PDFs have watermarks?

No, all signed PDFs are completely free from watermarks. Your documents maintain a professional appearance with only your signature visible exactly where you placed it.

What types of documents can I sign with e-signatures?

E-signatures are valid for most documents including contracts, agreements, NDAs, employment offers, rental leases, consent forms, approvals, and business documents. Some exceptions include wills, court orders, and adoption papers which may require notarization.

How do I position my signature on the PDF?

Use preset positions like bottom-right, bottom-left, or top-right for quick placement. For precise control, enable custom positioning and drag your signature to any location on the PDF. You can also adjust the signature size using width and height sliders.

What happens to my signature after I upload it?

Your signature image is used only to sign your specific PDF document and is deleted from our servers within 1 hour. We don't store signatures for reuse. Each signing session requires a fresh signature upload for your security.

Can I sign password-protected PDFs?

You need to remove password protection before signing. Use our PDF Unlock tool first to remove the password, then proceed to sign the unlocked PDF. This ensures the signature can be properly embedded in the document.

Does the signature include legal metadata?

Yes, each signature includes embedded metadata with timestamp, signer name, email, signature reason, and IP address. This metadata creates an audit trail that strengthens legal validity and proves when and who signed the document.

Can businesses use this for customer contracts?

Yes, businesses can use our ESIGN Act compliant tool for customer contracts, vendor agreements, employee documents, and internal approvals. The free version supports unlimited signatures. For advanced features like signature workflows and team management, consider our business plans.

What file size limit is there for signing PDFs?

Free users can sign PDFs up to 100MB. The signature process doesn't significantly increase file size - typically adding only 50-200KB depending on signature image quality. Signed PDFs download instantly after processing.
