How to use
01
Upload and create your signature
Drop the PDF in. Draw with a mouse or finger, type your name and pick a style, or upload a photo of your signature. Open Add initials too if the document needs initials.
02
Add items and place them
Press Signature, Initials, Name, Date, Text or Checkmark, or upload a stamp image. Drag each item into place, pull its corner to resize it, and use Place on to repeat it on other pages.
03
Sign & download
Check each page with the page arrows, then press Sign & download. Every item is added at its exact spot, and the file saves with a -signed suffix.
Why Sign PDF Online
- Draw, type or upload your signature and initials, in any ink colour.
- Add name, date, text, checkmarks and a company stamp.
- Place items on one page, all pages, the last page or pages you choose.
- An electronic signature image, not a certificate-based digital signature, with no upload.
Electronic signature vs digital signature
The two terms are often mixed up. This tool makes an electronic signature. If a form asks for a digital signature certificate, a DSC or a qualified signature, an image from this page will not meet that requirement.
| Electronic signature (this tool) | Digital signature (certificate) | |
|---|---|---|
| What it is | An image of your signature placed on the page | Cryptographic data added with a certificate issued to you |
| Proves who signed | No, it relies on context such as the email trail | Yes, the certificate identifies the signer |
| Shows later changes | No | Yes, readers flag edits made after signing |
| What you need | A browser | A certificate from a provider and software that applies it |
| Typical use | Leases, consent forms, offer letters, NDAs | Tenders and some company, tax and court filings |
Items you can place and where they go
Each item keeps its own position and page rule, so a long contract can take initials on every page and a full signature, name and date on the last one in a single pass.
| Item | Made from | Typical Place on setting |
|---|---|---|
| Signature | Your drawn, typed or uploaded signature | Last page |
| Initials | Drawn, typed or uploaded initials | All pages but last |
| Name and Text | Real text in Helvetica, any size and colour | Last page |
| Date | Today's date in your chosen format, editable | Last page |
| Checkmark | A tick symbol | Only this page |
| Company stamp or image | An uploaded PNG, JPG or WebP | Last page or all pages |
Legal status of electronic signatures
This is general information, not legal advice. Rules differ by country and by type of document, and the person or organisation receiving the document decides what it accepts.
- United States: the ESIGN Act and state laws based on the UETA give electronic signatures legal effect for most contracts. Wills and some family law and court documents are excluded.
- United Kingdom: electronic signatures are generally accepted for contracts, and the Electronic Communications Act 2000 allows them as evidence. Deeds have extra witnessing requirements.
- European Union: eIDAS recognises simple, advanced and qualified electronic signatures. A signature image is a simple one, and only a qualified signature automatically counts the same as handwriting.
- India: the Information Technology Act 2000 recognises electronic records and approved signature methods such as Aadhaar eSign and Digital Signature Certificates. An image signature is not one of those methods, and wills, powers of attorney and property sale contracts fall outside the Act.
Common questions
Is a drawn signature on a PDF legally valid?
For many everyday agreements, yes. Laws such as the US ESIGN Act and the EU eIDAS regulation accept electronic signatures, and what matters is that both sides intended to sign. Some documents, such as wills, still need ink or a certified signature, so check anything unusual. This is general information, not legal advice.
How is signing a PDF here different from a certified digital signature?
A digital signature uses a certificate to prove who signed and to show whether the file changed afterwards, and readers display a verification badge. This tool places a picture of your signature instead. It records your mark, but it cannot prove who made it or detect later edits.
Can I type my name or upload a signature image to sign a PDF?
Yes. The Type tab turns your name into a signature in one of seven styles, using handwriting-style fonts installed on your device, so the look varies a little between computers. The Upload tab takes a photo or scan of your signature and removes the white background.
How do I put my signature in the right place on the PDF?
Press Signature and a box appears on the page preview. Drag it onto the signature line and pull the corner handle to make it bigger or smaller. Where it sits in the preview is where it lands in the downloaded file.
Can I sign more than one page of the same PDF?
Yes. Place a signature, then set Place on to All pages, All pages but last, Last page or Custom pages such as 1, 4-6. You can also go to another page with the arrows and add a separate signature there.
Can I add the date or my initials when signing a PDF?
Yes. Press Date to add today's date in the format you pick, such as 31/12/2025 or 2025-12-31, and edit the text if you need another date. Open Add initials too to draw or type initials, then press Initials to place them.
Can I add a company stamp or seal to a PDF?
Yes. Upload a photo or scan of the stamp under Company stamp or image. Keep Remove white background ticked so only the ink shows, then drag and resize it like a signature.
Does my contract get uploaded when I e-sign a PDF here?
No. pdf.js shows the page and pdf-lib adds the signature, both in your browser, and the download is created on your device. The confidential text is never sent to anyone.
Why does my signature look shaky when I sign a PDF with a mouse?
Mouse and trackpad strokes are hard to control. Draw larger than feels natural, since the signature is scaled down when placed, use Undo stroke to fix a slip, or use the Type or Upload tabs. On a phone or tablet, drawing with a finger usually looks more natural.
What should both parties keep after exchanging a signed PDF?
Keep the final PDF together with the email thread that sent it. Because this signature is an image rather than a certificate, the record of who sent what and when is what backs it up if the agreement is ever questioned.
