To create electronic signature images that look good on a document, you have three choices: draw your signature on a screen, type your name, or photograph the signature you write with a pen. The PDFNova Sign PDF tool offers all three, and it places the result straight onto your PDF so you do not need separate design software. Everything happens in your browser, so the document is not uploaded to a server.
Each method suits a different situation. Below you will find how each one works, how to get a clean result, and which to pick for the document in front of you.
First, what an electronic signature actually is
An electronic signature is any mark made electronically that shows you agree to or approve a document. In its simplest form it is a picture of your signature placed on the page. That is what PDFNova creates.
It is different from a certificate-based digital signature, which relies on a digital certificate issued to the signer and can show whether a file was changed after signing. PDFNova does not create that kind. If an organisation specifically asks for a “digital signature certificate”, a drawn or typed signature will not meet that request.
Option 1: Draw your signature
Drawing is the closest thing to signing on paper. It works best on a touch screen, where your finger or a stylus moves the way a pen does.
- Use your phone or tablet if you can. A mouse or laptop trackpad tends to produce stiff, wobbly lines.
- Turn the phone sideways. A wider drawing area gives your signature room to flow.
- Sign at normal speed. Slow, careful strokes look shakier than a confident quick one.
- Redo it. The first try is rarely the best. Clear it and draw again until it looks like you.

Option 2: Type your name
Typing is the fastest method. You enter your name and the tool turns it into a signature you can place on the page. It is tidy and always readable, which is helpful when your handwriting is not.
A typed signature is a sensible choice for internal approvals, routine forms and quick confirmations. It feels less personal than handwriting, so for a contract with a new client or a formal letter, many people prefer a drawn or photographed signature. Type your name exactly as it appears elsewhere in the document, with the same spelling and order.
Option 3: Upload a photo of your pen signature
This method gives the most authentic look, because it is your real signature. It takes two minutes of preparation, and the quality of the photo decides the quality of the result.
- Take a clean sheet of plain white paper. Avoid lined or coloured paper.
- Sign in the middle with a dark pen. Black or dark blue ink with a medium tip shows up best.
- Place the paper flat near a window or under bright, even light.
- Hold the phone directly above the paper so the signature is not slanted, and make sure your hand casts no shadow.
- Take the photo and crop it tightly around the signature.
- Upload the photo in the signing tool and place it on your document.
Keep that photo somewhere private on your device. It is a copy of your signature, so treat it with the same care as an ID document and do not share it in chats or group folders.
Draw, type or photo: a quick comparison
| Draw | Type | Photo | |
|---|---|---|---|
| Speed | Fast | Fastest | Needs a little setup |
| Looks handwritten | Yes | No | Yes, it is your real signature |
| Best device | Phone or tablet | Any | Any, with a phone camera for the photo |
| Good for | Most everyday documents | Approvals and routine forms | Contracts and formal letters |
How to create electronic signature and place it on a PDF
Once you know which style you want, adding it to a document follows the same path every time.
- Open the Sign PDF tool and add your PDF from your device.
- Choose draw, type or upload, and create the signature.
- Move to the page that has the signature line.
- Place the signature on the line and resize it so it fits without touching the printed text.
- Add the optional date if the document asks for one.
- Download the signed PDF and open it to check the result.
The download goes directly to your device. PDFNova is free to use, asks for no sign-up and adds no watermark to the signed file.
Mistakes that make a signature look unprofessional
- Oversized signatures. A signature that fills a quarter of the page looks odd. Match it to the line.
- Grey or yellow photo backgrounds. These come from poor light. Retake the photo in brighter, more even light.
- Signing the wrong page. Contracts often have a signature block on the last page and other places to sign earlier. Scroll through the whole file.
- Different names. If the document says “Muhammad Ali Khan” and you type “M. Ali”, the mismatch can cause questions.
- Signing a draft. Make sure you have the final agreed version before you sign.
When a simple signature is enough, and when it is not
For a great deal of daily paperwork, a simple electronic signature does the job: quotations, purchase orders, internal forms, permission slips, freelance agreements. Our PDF tips for freelancers covering invoices, contracts and proposals show where signing fits into client work.
Some documents carry stricter requirements, such as certain property, court, banking or government papers. Requirements vary by country and by organisation. Before you rely on any electronic signature for something important, read whether electronic signatures are legally valid and what you should know, and confirm with the party receiving the document. This is general information, not legal advice.
After signing a sensitive document, you may want to restrict editing or add an open password with Protect PDF before you send it.
Frequently asked questions
Can I create an electronic signature for free without an app?
Yes. PDFNova runs in your browser, so there is nothing to install. Open the signing tool, create your signature and place it on your PDF.
Which pen is best for a signature photo?
A dark pen with a medium tip on plain white paper. Thin, pale ink can break up or fade when photographed.
Is a typed name a real electronic signature?
A typed name can count as a simple electronic signature in many situations, but acceptance depends on local rules and on the organisation you send it to. Ask them if you are unsure.
Can I add a date next to my signature?
Yes. The tool has an optional date that you can place beside your signature before downloading the file.
Pick the style that fits your document, then open Sign PDF to draw, type or upload your signature and put it on the page in a minute or two.
