About This Tool
Sign PDF allows you to add electronic signatures to your PDF documents quickly and securely. Create your signature by drawing, typing, or uploading an image, then place it anywhere on your document.
You can add multiple signatures to a single document, resize and position them precisely, and save your signature for future use. The tool is perfect for contracts, agreements, forms, and any document requiring your signature.
All signing happens locally in your browser, ensuring your documents and signature remain private.
For a natural-looking signature, draw it with a finger or stylus on a touchscreen, or upload a photo of your signature on plain white paper taken in good light. Zoom in on the signature line before placing it, then resize so it fits the space without covering printed text. If a document needs initials on every page, add them as a separate small signature and place a copy on each page before you sign the final line.
A signature image is something you never want floating around on someone else's server. With TokPDF, both the document and your signature are handled entirely in your browser using WebAssembly, so neither is uploaded. A saved signature is kept only in your own browser's local storage. That makes it practical to sign a lease or consent form on the spot, from a borrowed laptop or your phone, without signing up for an e-signature service.

Frequently Asked Questions
Is an electronic signature legally binding?
Electronic signatures are legally recognized in most countries. However, some documents may require specific types of digital signatures. Check your local regulations.
Can I save my signature for future use?
Yes, you can save your signature to your browser's local storage for quick access when signing future documents.
Can I add multiple signatures to one document?
Yes, you can add as many signatures as needed, positioning each one independently on any page.
How do I sign a PDF on my phone?
Open tokpdf.com in your mobile browser, load the PDF, and draw your signature with your finger. Place and resize it on the signature line, then download the signed document. Everything runs in the browser, so no app is needed.
Can I add the date and my printed name next to my signature?
Yes. Use the text option to type your name and the date, then place each item where the document asks for it. Typed text can be resized and moved independently of the signature so it lines up with the form fields.
Is this a digital signature with a certificate?
No. Sign PDF adds a visual electronic signature to the page, which is accepted for many everyday agreements. It does not attach a certificate-based digital signature. If a recipient requires a certified digital signature, check their specific requirements.
Can someone else sign the same PDF after me?
Yes. Send them the signed file and they can open it in TokPDF or any PDF tool to add their own signature. Each signer adds theirs in turn, since TokPDF does not route documents between people or collect signatures on your behalf.
