How to sign a PDF online
- Add the PDF you need to sign.
- Add your signature from a photo of it on paper, or draw it. It stays in this browser for the next document.
- Place it on the page, resize or turn it, and download the signed copy.
Your real handwritten signature, not a typed font
- From a photo: the paper becomes transparent and the ink keeps its own color, blue or black, cropped to the signature.
- Drawn: blue or black ink, with a mouse, a trackpad, a finger on a phone or a pen on a tablet.
- Add the same signature or your initials to every page at once.
- Signatures go into the page on top; the page's own text and links stay as they are.
Sign PDFs without uploading them
- Your files are opened and changed by your browser, on your device. They are never sent to our server or to anyone else.
- No account, no sign-up, no email.
- No ads, no analytics, no tracking scripts, and this site sets no cookies.
- Signatures and stamps you add are kept only in this browser, so they are there next time; the browser may clear them.
- Your original file never changes: every result is a new file that your browser downloads.

Sign PDF: questions
How do I sign a PDF for free without Adobe?
Add the PDF here, add your signature from a photo or draw it, put it on the page and download the signed copy. It's free and works in any current browser, with no account.
Can I add an image of my signature to a PDF?
Yes. Use a photo or scan of your signature on white paper: 1Scanner removes the paper and keeps only the ink, so it looks signed by hand on the page.
Can I sign a PDF online without an account?
Yes. There is no account or sign-up, and your PDF and signature stay in your browser.
How do I sign a PDF on my phone?
Open this page in your phone's browser, add the PDF from your files, and draw your signature with your finger or use a photo of it.
Is this an electronic signature or a digital signature?
1Scanner puts a picture of your handwritten signature on the page, like signing a printout. It doesn't create a certificate-based digital signature. Whether a signed copy is enough for a given document depends on who asks for it.
Is it safe to sign a PDF online?
Here nothing is uploaded: your browser adds the signature on your device. Your signature is kept only in this browser.
