Sign PDF Online Free — Draw Your Signature on a PDF
When a form, a letter or a simple agreement needs your signature, printing it, signing it by hand and scanning it back is slow and wasteful. This free PDF signing tool lets you draw your signature with a mouse or a finger, or type your name in a handwriting style, and place it exactly where it belongs on the page, usually at the bottom right above the signature line. You choose the page and the position, and the signed copy is ready to download in seconds. Everything happens in your browser: your PDF is never uploaded to a server, never stored anywhere, and never seen by anyone else. The original file on your computer is never changed; you always download a new, signed copy, so keep the clean original safe. This adds a visible signature image to the PDF. It is NOT a certified e-signature service: no audit trail, no identity verification, no tamper-evident certificate. Check whether your recipient or jurisdiction accepts a simple electronic signature.

How to Use
- Add your PDF. Click the drop zone and choose one PDF file, or drag it straight from your computer into the box. Its name and size appear below the box, and the page list is filled in so you can pick the page to sign.
- Draw or type your signature. Draw in the box with your mouse, finger or stylus. If drawing is awkward, type your name underneath instead for a handwriting style. Click Clear Signature to start again.
- Choose the page and position. Pick the page that carries the signature line, usually the last page, and choose where the signature should sit. Bottom right is the usual place for a signature line, while bottom left suits a second signer or a witness.
- Click Sign PDF and download. The tool loads its PDF library and places your signature image on the page you chose. When the result appears, click Download signed.pdf and open it to check that the signature sits neatly above the line.
Worked Example
Suppose you have a 1-page permission form with a signature line at the bottom right, and you need to send it back signed today. Add the PDF, draw your signature in the box, or type your name if drawing is difficult, and leave the page set to page 1 and the position set to bottom right. Click Sign PDF. The expected result is a new file, signed.pdf, with exactly 1 page, because signing adds an image to a page rather than adding a page. The signature appears in the bottom right corner of that single page, just above the printed line, and the rest of the form is unchanged. A 1-page PDF always stays 1 page after signing, and a 5-page PDF signed on page 5 stays 5 pages.
Why Sign a PDF in Your Browser?
Most online signing tools ask you to upload your document to a remote server, where you have no control over how long it is kept or who can see it. That is a real risk when the file is a contract, a medical form, a tenancy agreement or a financial document. This tool takes the opposite approach: the signing code runs on your own device, inside your browser, and the file never travels over the internet at all. It is also much faster than the print, sign and scan routine, which needs a printer, a pen and a scanner, and often produces a blurry, oversized file. Here the signature is placed as a clean image on the original PDF, so the text stays sharp and the file stays small.
Tips for a Neat Signature
Draw your signature in one smooth motion, fairly large in the box, because a small, cramped drawing looks faint when it is shrunk onto the page. Always check the signed copy before you send it, and make sure the signature sits above the line rather than across the printed text. Keep your original, unsigned file, because a signature placed into a PDF cannot be cleanly removed later. This adds a visible signature image to the PDF. It is NOT a certified e-signature service: no audit trail, no identity verification, no tamper-evident certificate. Check whether your recipient or jurisdiction accepts a simple electronic signature. If the recipient needs a certified signature with proof of who signed and when, use a proper e-signature service instead, and do not rely on this tool for that job.
Frequently Asked Questions
Is it really free to sign a PDF here?
Yes. Drawing or typing a signature onto a PDF on this page is completely free, with no account and no sign-up. You can sign as many PDFs as you like, and the signed file belongs to you.
Are my PDF files uploaded to a server?
No. Your PDF never leaves your browser. The signature is placed entirely on your device using a PDF library loaded from this site, so your document is never uploaded, stored or seen by anyone else.
Is this a legally certified e-signature?
No. This adds a visible signature image to the PDF. It is NOT a certified e-signature service: no audit trail, no identity verification, no tamper-evident certificate. Check whether your recipient or jurisdiction accepts a simple electronic signature.
Can I remove a signature after I download the PDF?
A signature placed into a PDF is part of the page, so it cannot be cleanly removed by this tool. Always keep your original, unsigned file, and only share the signed copy. If you need to change the signature, sign a fresh copy from the original.
What if my PDF is password-protected?
Password-protected PDFs cannot be opened here, because the tool cannot read them without the password. Remove the password in your PDF reader first, save an unlocked copy, and then sign that copy.
