A clear comparison of scanned, electronic and digital signatures: what each one is, when a simple signature picture is enough, and when you need something stronger.
People use “electronic signature”, “digital signature” and “signed PDF” as if they were the same thing. They are not, and the difference matters when a bank, a government office or a company asks you to sign. This guide explains the three common types in plain language so you can pick the right one. It is general information, not legal advice.
This is the simplest kind. You sign on paper, take a photo or scan it, and place that picture on a document. Or you draw your signature on a screen with a finger, a stylus or a mouse and place it on the page. The result is a visual signature: it shows what your signature looks like, and that is all.
The Add Signature tool on Docsworker is this type. You draw or type your signature, place it on a PDF or an image, and download the result.
An electronic signature is a broad term for any electronic way to show that you agree to something. It can be a typed name, a ticked box, a drawn signature or a click on “I agree”. What gives it weight is not the picture but the surrounding evidence: who you are, that you intended to sign, that you consented to do it electronically, and a record of when it happened. E-signature services add this evidence in the form of audit trails, email verification and timestamps.
Many countries have laws that recognise electronic signatures for a wide range of agreements. Well-known examples are the ESIGN Act in the United States and the eIDAS rules in the European Union, and Pakistan has the Electronic Transactions Ordinance of 2002. These laws usually have exceptions, for instance for certain wills, family matters or property transfers, so the right form depends on what you are signing and where.
A digital signature is a cryptographic method. A certificate issued by a trusted authority identifies the signer. The software then creates a mathematical fingerprint of the document and locks it with the signer’s private key. If anyone changes even one character after signing, the signature shows as invalid. It also shows who signed and when.
The key point: an electronic signature can be a picture; a digital signature cannot. A picture of a signature, however nice it looks, is not a digital signature.
Ask a simple question: what does the person receiving it need? If they only need to see your signature on a form, for example a school permission slip, a letter, a delivery receipt or a simple internal approval, a visual signature is usually fine. If the recipient names a particular e-signature service or says “certified”, “notarised” or “digitally signed”, follow their instruction. When in doubt, ask them in writing which kind they accept before you sign. It costs one message and can save you from signing twice.
For a more natural look on a phone, draw slowly with your finger and zoom in before you place it. The step-by-step signature guide has more details.
A scanned or drawn signature is a convenient picture. An electronic signature is a legal concept backed by records. A digital signature is a secure, certificate-based seal. Choose by what the receiving side requires, not by what looks best on the page.
It depends on the country, the type of document and what the other party accepts. Many places recognise electronic signatures for ordinary agreements, but some documents need a stronger form or a witness. Check with the recipient or a legal professional for anything important.
No. Docsworker places a visual image of your signature on the page. It does not create a certificate-based digital signature and it does not lock the document against later changes.
Yes. A visible signature is a picture, so anyone with the file could copy it. Sign only documents you trust, and send signed copies only to the people who need them.
Use a certified e-signature service or the signing method the recipient names. A picture of a signature will not meet that requirement.
