The terms "electronic signature" and "digital signature" sound interchangeable, but one describes a broad signing category and the other a cryptographic technique. A signature image made on a device is not automatically a certificate-based digital signature.
Electronic signatures
An electronic signature can be an electronic indication of intent to agree, depending on the context and applicable rules. Examples include:
- A typed name in an email
- A scanned image of a handwritten signature
- A click on an "I agree" button
- A drawn signature on a touchscreen
Legal status: Frameworks such as the US ESIGN Act and EU eIDAS address electronic signatures, but requirements and exceptions depend on the document and jurisdiction. A mark alone does not establish enforceability.
Security: A plain image or typed name has no built-in verification. An electronic-signing service may add authentication, consent records, and audit evidence without making the visible mark itself cryptographic.
Digital signatures
A digital signature uses a private signing key and corresponding verification key to:
- Check that a signature matches the signed data
- Detect changes to the data covered by the signature
- Support identity verification when a trusted certificate binds the key to a signer
Legal status: Depends on the signing process and applicable rules. Using cryptography or possessing a certificate does not automatically make every signature equivalent to handwriting.
Security: Public-key cryptography provides verifiable integrity. Trust also depends on certificate validation, key protection, and who controlled the key. Timestamps and audit trails are additional workflow features, not automatic guarantees; a signature does not make disputes impossible.
For the technical distinction, MDN's cryptographic signing reference describes signing data with a key and verifying the resulting signature. Exporting an image is a different operation; Signature Maker does not provide that cryptographic workflow.
Comparison
| Feature | Plain image or typed mark | Cryptographic signature |
|---|---|---|
| Identity verification | Not provided by the mark | Depends on key and certificate trust |
| Tamper detection | Not provided by the mark | Covers the signed data |
| Audit trail | Depends on the surrounding service | Depends on the surrounding service |
| Legal effect | Depends on the process and rules | Depends on the process and rules |
| Setup | Create and place a mark | Signing software and a signing key; often a certificate |
When to use electronic signatures
- Internal documents and approvals
- Informal agreements
- Low-risk transactions
- When the recipient accepts the process and its evidence is appropriate for the risk
When to use digital signatures
- When the recipient explicitly requires a certificate-based signature
- When you need independently verifiable integrity of the signed data
- When financial, government, or regulated workflows specify particular signing credentials
- When identity verification is critical, alongside appropriate authentication and certificate checks
How electronic and digital signatures actually relate
The cleanest way to keep these straight: "electronic signature" is a broad legal category, while "digital signature" is a specific technology. Cryptographic signing can be used in an electronic-signing workflow, but it also has uses outside agreements, such as software signing. Intent, identity evidence, and required procedures still matter; neither a drawing nor a valid cryptographic check proves all of them by itself.
Concretely, the two leave very different artifacts behind:
- An electronic signature might be a row in a log ("user X clicked Agree at 14:32"), a typed name, or a PNG of a drawn signature dropped onto a PDF.
- A digital signature is cryptographic data produced using a signing key and verified against the signed content. A signed PDF may bundle certificates and validation information. Changes to covered data can fail verification; some PDF workflows allow later additions, so the verifier must also report what changed and whether it was permitted.
If you only need a clean image of your handwritten mark to place in a form, our guide to creating a signature image walks through drawing or uploading one. Signature Maker downloads transparent PNGs and SVGs of drawn paths; uploaded scans produce PNG, not vector tracing. It does not open PDFs, issue certificates, authenticate signers, or create audit records.
Legal standing at a high level (ESIGN and eIDAS)
Note: This section is informational only and is not legal advice β rules vary by country, document type, and industry, so confirm the requirements for your own situation.
Two frameworks you may encounter are ESIGN in the US, alongside state law, and eIDAS in the EU. Do not reduce either to "a pasted image is always valid" or "a certificate always has more legal weight."
The European Commission's eSignature overview explains that advanced electronic signatures (AES) and qualified electronic signatures (QES) have specific requirements beyond their appearance. QES involves a qualified certificate and qualified creation device, not just any certificate or an SVG export. A certificate-based product does not automatically satisfy every AES or QES requirement.
For a consequential document, confirm the accepted signature type, identity checks, consent and retention requirements, and any exceptions with the recipient or a qualified adviser. This is a technical overview, not a review of all laws or a compliance assessment of a signing service.
A closer comparison by what each one delivers
| Signature type | What it provides | Tamper-evidence | Identity binding | Possible use | Setup |
|---|---|---|---|---|---|
| Typed name or "I agree" click | A mark or recorded action; intent needs context | None by itself; service may retain evidence | Depends on authentication | Internal approvals or agreements if accepted | Form or signing service |
| Scanned or drawn signature image | A recognizable visual mark, not proof of who placed it | None; the file can be reused | None by itself | PDF forms or letters if accepted | Image maker and compatible document editor |
| Cryptographic digital signature | Verification against signed data and a key | Changes to covered data can be detected | Depends on trusted certificate and key control | Workflows requiring verifiable integrity | Signing key and software; credentials as required |
Choosing the right signature for the job
Match the signature to the risk, not to whichever tool is closest:
- A visual mark is accepted: For an internal approval or form that accepts images, create a graphic with Signature Maker. Draw, Undo, and prepare PNG/SVG downloads, or upload a JPG/PNG scan and adjust the paper threshold. Review cleanup before downloading; it is not signer verification.
- You want a crisp mark in email or documents β size it so it stays sharp without bloating the message; our note on email signature image size covers the dimensions and file-size targets.
- Money, identity, or compliance is involved: Confirm the specific signing process and credentials required. If certificate-based signing is required, use a service that actually supplies it, not an image-export tool.
- The document may be scrutinized later β if a dispute is plausible, tamper-evidence and a verifiable audit trail matter far more than convenience.
Some e-signature services combine a simple visible mark with cryptographic protection and audit evidence. Check the selected product and workflow: a provider's brand name alone does not tell you whether the document carries a certificate-based signature or how identity was checked.
Frequently Asked Questions
Is an electronic signature legally binding?
It can be, but not every mark or click is enforceable in every situation. Check the applicable rules, document exceptions, parties' intent and consent, and the evidence retained by the signing process. This guide and Signature Maker do not assess legal validity.
Is a digital signature the same as an electronic signature?
Not exactly. A digital signature is a cryptographic technique that can be part of an electronic-signing process. An electronic signature is the broader category; a typed name or drawn image may be used without cryptography when the process permits it.
Can a scanned image of my signature be forged?
Yes. An image carries no cryptographic protection, so anyone who obtains the file can paste it onto another document. Keep it private and use a signing workflow with appropriate identity and integrity checks for sensitive documents.
Do I need a certificate authority for an electronic signature?
A signature image does not need a certificate. Cryptographic signing requires a key pair; certificate-based document workflows use certificates to establish trust in that key. A self-signed certificate is not automatically trusted by a recipient, and a certificate alone does not establish legal validity.
Which should I use for a business contract?
Use the process accepted by the parties and required for that contract. For consequential agreements, confirm identity verification, integrity protection, audit evidence, and any certificate requirements rather than relying on a reusable PNG or a product label.
Tools
- Image creation: Signature Maker exports reusable graphics for compatible editors.
- Document signing: A separate PDF editor or signing service is needed; verify whether it provides annotation, audit records, or certificate-based signing. An email footer is not document signing.
