Questions about Fill & Sign
Frequently asked technical and operational questions about fill & sign.
How do I fill out interactive PDF forms and sign them?
The tool renders fillable text fields, checkboxes, and radio buttons for immediate input, and provides a signature pad to draw, type, or upload your signature.
Can I save my filled form as a flattened, tamper-proof document?
Yes. You can export the completed form with appearances permanently baked into the PDF content stream to prevent subsequent alteration by recipients.
Is a digital signature created here legally binding?
An electronic signature image satisfies general business agreements in many jurisdictions. However, for specialized regulatory filings requiring cryptographic PKI certificates, check local statutory requirements.
