About Sign PDF
Sign PDF lets you draw your signature and drop it onto a PDF, so you can sign a document without printing it, signing on paper, and scanning it back in. Draw your signature with a mouse, trackpad, or finger, choose the page, then drag the signature to where it belongs — the signature line of a contract, a form, a letter, or an initials line. When it looks right, you save the signed PDF and can send it back the same way it arrived.
If you have been searching for how to sign a PDF, or hunting for free PDF-signing freeware to install, this does the same job with nothing to download. It is a plain web page: no account, no sign-up, no usage limits, and no watermark stamped across your file. You can sign one document or a stack of them, on a laptop or a phone, without hitting a paywall or a trial timer.
Everything runs in your browser. The signature is captured on a canvas and written into the PDF with pdf-lib, entirely on your own device, so your signature and your document are never uploaded to a server.
Frequently asked questions
- How do you sign a PDF?
- Open your PDF, draw your signature, pick the page you want to sign, and drag the signature onto the signature line. When it is positioned right, save the signed PDF — no printing, paper, or scanner needed.
- Is it free, and do I need an account?
- Yes, it is free, with no account and no sign-up. You can sign as many PDFs as you like, with no usage limits and no watermark.
- Is there free software or freeware to sign a PDF?
- You do not need to install any freeware or desktop program. This works as a web page in your browser, so there is nothing to download, license, or keep updated.
- Is my signature or document uploaded anywhere?
- No. You draw the signature on a canvas in your browser, and it is placed into the PDF with pdf-lib on your own device. Neither the signature nor the file is sent to a server.
- How do I draw and place the signature?
- Draw your signature with a mouse, trackpad, or finger, then move it onto the page and position it over the signature line. When it looks right, save the signed PDF.
- Can I sign a PDF on my phone?
- Yes. You can draw your signature with your finger on a touchscreen, so signing works on a phone or tablet as well as with a mouse or trackpad on a computer.
- Can I put the signature on any page?
- Yes. You choose which page to sign and where on that page the signature sits, so you can place it on the last page, an initials line, or wherever the document needs it.
- What kinds of documents can I sign?
- Any PDF works — contracts, agreements, forms, and letters. You draw and drop the signature wherever the document needs it, then save and return the file.
- Will the signed PDF still open and email correctly?
- Yes. It saves a standard PDF with your signature drawn onto the page, so you can email it, upload it, or print it like any other PDF and send it back the same way it arrived.
- Is this a legally certified digital signature?
- It adds a visible, hand-drawn signature to the page — the same thing you would get by signing on paper. It is not a certificate-based cryptographic digital signature, so if a document specifically requires a verified digital certificate, use a service built for that.
