What makes a good electronic signature

A good e-signature is legible enough to be recognisably yours, consistent enough that you can reproduce it, and clean enough to look right at small sizes. It does not need to be elaborate. Some of the most recognisable signatures are just a confident initial and a line. What looks bad is hesitation: wobbly strokes, faint lines and a signature that is visibly different every time.

Practically, aim for a signature that still reads when it is about 3 to 4 centimetres wide, since that is how it will usually appear on a document. Avoid very thin strokes, which disappear when scaled down, and very long flourishes, which collide with text above and below the signature line.

Drawn or typed: which should you use?

A drawn signature feels more personal and resembles your paper signature, which some people and some counterparties prefer. It works best on a touchscreen or with a stylus. On a laptop trackpad, it often looks childish; that is the hardware, not your handwriting.

A typed signature, your name set in a handwriting-style font, is neat, consistent and quick. Legally it is generally treated the same as a drawn one, because what matters is your intent to sign, not the shape of the letters. Our opinion: if you have a touchscreen, draw it; if you are on a desktop, type it and pick a font that looks like something a person might write.

An honest legal note: the image alone is weak evidence

A signature image is not, by itself, proof of anything. Anyone who has seen your signature on one document can copy the image into another. That does not make image signatures useless; in many places a signature can be any mark made with the intent to sign, and pasting yours into a document you are sending is a clear act of intent.

What gives an electronic signature weight in a dispute is the surrounding evidence: who received the document, from which email, when they opened and signed it, and proof the file has not changed. That is what eSignSimple adds when you send a document for signature, with an audit trail, certificate of completion and SHA-256 fingerprint. Use this generator to create your signature; use a proper signing flow when you need to prove someone else's.

How to use your signature PNG in Word, Google Docs and email

Download the signature as a PNG with a transparent background so it sits cleanly over lines and coloured paper. The generator is free inside your eSignSimple account, and the image is created in your browser and never uploaded. Better still, if the Word document needs someone else's signature too, skip the image entirely: upload the .docx to eSignSimple, place signature fields, and send it; we convert it to PDF and every signer gets an audit trail.

Microsoft Word: choose Insert, then Pictures, and select the PNG. Right-click the image, choose Wrap Text and then In Front of Text so you can drag it onto the signature line without pushing text around. Resize from a corner handle to keep proportions.

Google Docs: choose Insert, Image, Upload from computer. Select the image and choose In front of text from the options bar to position it freely. If you sign often, keep the PNG somewhere handy in Google Drive so you can insert it from there.

Email signatures: most mail apps let you add an image in the signature settings. Scale it to around 150 to 200 pixels wide so it does not dominate the message. Be aware that adding your handwritten signature to every email makes it easy for anyone to copy; many people prefer a typed name in email and keep the handwritten version for documents.

Why does my signature PNG show a white or black box?

The PNG you download has a transparent background, and it is trimmed close to the ink, so there is no empty margin around it. If you see a box, something along the way has flattened that transparency. The usual culprits are converting the file to JPG (JPG cannot store transparency, so the background becomes white or black), pasting it through an app that only handles plain images, or a preview app that shows transparent areas as a checkerboard or a dark fill even though the file itself is fine.

The fix is to keep the original PNG and insert the file itself, rather than a screenshot or a copy-paste of it. In Word and Google Docs, insert it from your computer as described above. If a website or form only accepts JPG, that service will add a background; choose a white page colour so it blends in, or ask whether they accept a typed signature instead.

Getting a good-looking signature with a mouse or trackpad

Drawn signatures look worse on a laptop for a physical reason: a trackpad measures finger movement, not pen pressure or angle, and most people move slowly and carefully, which produces wobbly lines. Counter-intuitively, signing a little faster usually looks better. Make the signature large, filling most of the pad, and sign in one or two confident strokes rather than many small ones. If it looks wrong, clear it and try again; the fifth attempt is usually the keeper.

The easiest upgrade is to use your phone. Sign in to your account on your phone, open the generator, and draw with your finger; the result is far closer to a pen signature. Download the PNG there, or simply use the phone for the documents you need to sign. If you mostly work at a desk, switch to Type mode: your name in a handwriting font looks tidy and identical every time, which is exactly what you want on a contract.

Make three versions: full signature, short signature and initials

Most people need more than one mark. A full signature goes on the last page of a contract. Initials go at the foot of each page of a lease or loan agreement, and next to any handwritten change. A short form, such as a first initial and surname, is useful for narrow boxes on forms and delivery notes. Create each one in the generator and save them with clear file names, such as signature-full.png, signature-short.png and initials.png, so you never have to squeeze a long signature into a tiny box.

Keep them in one private folder, not on your desktop or in a shared drive that colleagues can browse. A signature image is not a password, but there is no reason to make it easy to copy. And when you need someone else's signature rather than your own, skip the image entirely: send the document for signature so each signer gets their own link and you get an audit trail.

When should you not use a signature image at all?

Some documents need more than a picture, whatever the general law says. Wills, many property transfers and anything that has to be witnessed or notarised usually have formal requirements, and in most places a pasted image will not meet them; check local rules, or see our pages on witness signatures and notarization. Banks, courts and government portals often run their own signing or identity process and may reject a PDF with an image on it, so follow the method they ask for.

Be careful, too, when the document was prepared by the other side and you are sending it back by email. Before you add your signature, make sure you are signing the final version, and keep a copy of what you returned. If you want certainty about who signed what and when, the difference between digital and electronic signatures explains what each kind of evidence proves.
