To sign a PDF, open it above, then make your signature in the signature panel: draw it with a mouse or finger, type your name and pick a handwriting style, or upload a photo of your signature on paper. Press Add signature to page, drag it onto the signature line, pull the round corner handle to resize it, and press Download signed PDF.
Three ways to make your signature
- Draw works best on a phone or tablet with a finger or stylus. On a computer, a slow, steady mouse stroke gives a cleaner line than a fast one. Pick black or blue ink; blue makes it easier for someone to tell the signed page from a photocopy.
- Type gives a neat signature in one of three handwriting fonts. It suits forms where a printed name in signature style is accepted.
- Upload is the closest match to your real signature. Sign on plain white paper, take a photo straight on in good light, and keep Remove the paper background ticked. The paper turns transparent and only the ink is kept, so the signature sits cleanly on the page.
Adding the date and other text
Add date puts today's date in the format your device uses, and Add text places anything else you type, such as your printed name, initials or a place. Each item is added to the page you are looking at and can be moved and resized like the signature. To initial every page, scroll to each page and press the button again; the same signature is reused, so the file stays small.
Placing it precisely
Drag an item to move it, or select it and use the arrow keys for small steps; hold Shift for bigger ones. The plus and minus keys resize it and Delete removes it. Items stay inside the page edge, so nothing gets cut off. Pages that are turned sideways in the original PDF keep their orientation, and your signature is written the right way up on them.
Is a signature added this way legally valid?
A signature image placed on a PDF is a simple electronic signature. Many everyday documents accept it: rental and HR forms, permission slips, invoices, quotes and letters. Some documents need more. Certain contracts, tax filings and government submissions require a certificate-based digital signature, such as a DSC or Aadhaar eSign in India, which proves who signed with a cryptographic certificate. This tool doesn't create those. If you aren't sure which kind a document needs, ask whoever is asking you to sign it.
Our tool also doesn't lock the PDF after signing, so treat the signed file like any other copy you send.
Your PDF and signature stay on your device
Signing happens in your browser. The PDF, your signature and the finished file are never uploaded or stored, and nothing is remembered after you close the tab. That is the main thing to check before you sign a contract or an ID form on any website. Our guide to whether online file tools are safe explains how to confirm it yourself.
Limits
- Fillable form fields aren't filled in by this tool. Use Add text to place an answer on top of a printed field.
- A PDF protected against changes with an owner password can't be signed here. Save a copy without the protection in your PDF reader first.
- Very long documents open page by page as you scroll, so the first pages appear right away.
To make a large signed scan smaller for email, run it through Compress PDF. To send only the pages that need a signature, pull them out first with Split PDF, and use Merge PDF to put the document back together.
