Sign PDF
Add a visible electronic signature to a PDF directly in your browser. Draw, type or upload a signature and place it exactly where you need it.
This creates a visible electronic signature image inside the PDF. It is not a certificate-based digital signature.
How to sign a PDF with NeroTool
- Open the Sign PDF tool and choose your PDF.
- Draw your signature in the signature pad.
- Select the target page and adjust the signature width and position.
- Choose Apply Signature & Download PDF and review the signed copy.
Electronic signature vs. digital certificate
NeroTool places a visible signature image into the PDF. This is an electronic-signature workflow, not a certificate-based cryptographic digital signature. For contracts or regulated workflows that require identity verification, audit trails or certificate validation, use a service designed for those requirements.
Check the signed document
Open the downloaded PDF and verify the signature location, size and page before sending it. Keep the original document separately if you need an untouched copy for your records.
