Frequently Asked Questions
How do I sign a PDF online for free?
Upload the PDF, draw your signature in the box, choose where it goes and click Sign PDF.
Is my signature stored or uploaded?
No. The signature is drawn and applied locally in your browser and is never sent to any server.
Is this a legally binding digital certificate signature?
No — it places an image of your handwritten signature on the page, like signing a printout. It is not a cryptographic certificate-based signature.
Is the Sign PDF tool free and unlimited?
Yes. PDF Boy's Sign PDF tool is completely free, with no signup, no watermark and no limit on how many files you process.
Are my files uploaded to a server?
No. Everything happens locally in your browser, so your files never leave your device.
