How to use Sign PDF
- Open the PDF you need to sign. For a paper document, photograph or scan its pages instead.
- Draw your signature, type your name and pick a style, or photograph your signature on white paper: the paper is removed and only the ink is kept.
- The signature goes into the PDF's signature box if it has one, or near the bottom of the last page. Drag it into place and pull its corner to make it bigger or smaller.
- Add the date or your initials with the Date and Text tools, then save the signed PDF or share it.

About this tool
Signing a PDF used to mean printing it, signing it with a pen and scanning it back. Here you add a signature to a PDF in your browser: draw it, type it, or take a photo of the signature you wrote on paper, which is cleaned so only the ink is kept, like a pen signature. You can sign a PDF on an iPhone, an Android phone or a computer: with your finger on a phone, with a mouse, trackpad or pen on a computer. It suits contracts, rental agreements, offer letters, invoices and consent forms, and any other document you need to sign online.
This is an electronic signature (e-signature): a picture of your signature placed on the page, like a signed and scanned copy, not a certificate-based digital signature. In the US (the ESIGN Act) and the EU (eIDAS), a signature cannot be refused just because it is electronic, and electronic signatures are widely used for everyday agreements. Some documents, such as wills and certain court or government papers, still need a handwritten or certified digital signature, so check with whoever asked you to sign. When you save, the signature and any answers are locked into the page, so the PDF looks the same in every app.
Frequently asked questions
How do I sign a PDF online for free?
Open the PDF here, then draw your signature, type your name or photograph your signature, and choose Use this signature. It goes into the signature box, or onto the last page, where you can drag it into place. Choose Save PDF to download the signed file. There is no sign-up, limit or watermark.
Can I sign a PDF on my iPhone or Android phone?
Yes. Open this page in Safari or Chrome, choose the PDF from your files or downloads, and sign with your finger. Then save the signed PDF, or share it straight to email or a chat app.
Is an electronic signature legally binding?
For many everyday documents, yes: in the US (the ESIGN Act) and the EU (eIDAS), a signature cannot be refused only because it is electronic. Some documents, such as wills and some court and government papers, need a handwritten signature or a certificate-based digital signature, which this tool does not add. If in doubt, ask whoever needs the signed document.
How do I add a signature I wrote on paper?
Sign on plain white paper, then choose Photo in the signature window and take or choose a picture of it. The paper is removed and only the ink is kept, in black or blue.
Is my signature saved anywhere?
Only if you tick "Remember it on this device": it is then kept in this browser so you can sign faster next time, and you can remove it at any time. It is never uploaded.
Can I fill in the rest of the form too?
Yes. After signing, type into the PDF's own boxes, and add text, ticks, crosses and the date anywhere on the page.
Is my PDF uploaded?
No. The PDF is opened, signed and saved in your browser, and nothing is kept after you close the page.
Can I sign a PDF on a Mac?
Yes. It works in Safari, Chrome and Firefox on a Mac: draw your signature with the trackpad or mouse, place it on the page and download the signed PDF.
