How to Sign a PDF Online
Add an Electronic Signature to Your PDF
FreeToolIQ helps you place a visible electronic signature on a PDF document without installing additional software. You can draw your signature with a mouse or touchscreen, type your name, or upload an existing signature image.
Preview the document, navigate between pages, position your signature, and adjust its size before downloading. The original document remains on your device.
This tool adds a visible electronic signature image. It does not create a certificate-based cryptographic digital signature, identity verification, or a tamper-evident audit trail. Whether a signature is legally sufficient depends on the document, jurisdiction and applicable requirements.
