Frequently Asked Questions
Quick direct-answer guides about using this utility tool locally and securely.
How do I draw my signature on the PDF?
You can use your mouse or touch screen on the visual signature canvas pad, customize the pen width and color, and place it. You can also upload an existing PNG signature image.
Can I position and resize the signature inside the PDF?
Yes! After creating or uploading your signature, you can drag the signature box to any page and position, and resize it using the handles. Once placed, click "Apply & Download" to permanently write the signature into the PDF.
Is digital signing secure on this site?
Absolutely. The signing operation runs 100% locally in your browser. Your signature and document are never uploaded to our servers, keeping your signatures fully secure.
Is an electronic signature on a PDF legally valid?
Yes, electronic signatures are legally recognized and binding in most countries, including under the ESIGN Act in the United States and eIDAS regulation in the European Union. For standard contracts, agreements, and forms, an electronic signature carries the same legal weight as a handwritten one — though certain documents like wills or notarized deeds may still require wet-ink signatures depending on your jurisdiction.
What is the difference between an electronic signature and a digital signature?
An electronic signature is any mark — drawn, typed, or an uploaded image — that shows intent to agree to a document, which is what this tool provides. A digital signature is a more specific, certificate-based technology that uses cryptographic encryption to verify identity and detect tampering. For most everyday contracts, forms, and agreements, a standard electronic signature is sufficient.
Do I need to create an account to sign a PDF?
No, KuberAgent Sign PDF tool requires no registration or account creation — simply upload your document, create your signature, and download the signed file.
Can I add my signature to multiple pages of the same PDF?
Yes, you can place your created signature on every page that needs it before finalizing and downloading the signed document.
Can I type my signature instead of drawing it?
Yes, besides drawing with your mouse or touchscreen, you can also type your name in a signature-style font or upload an image of your handwritten signature — whichever method looks most professional for your document.
Does this PDF signer work on mobile devices?
Yes, since it runs entirely in your browser, you can sign PDFs on any device — Android, iPhone, tablet, or desktop — without installing an app.
