Frequently Asked Questions
Everything you need to know about our browser-native signature pad and professional export engine.
Is this signature generator free to use?
Yes. Our Signature Generator is 100% free with no hidden fees, no subscriptions, and no watermarks. It is a core utility of the FDM AI (Free Document Maker) ecosystem designed for professional use.
Are these electronic signatures legally binding?
Yes, in many jurisdictions (like the US via the ESIGN Act and the EU via eIDAS), electronic signatures are legally recognized. This tool provides the visual representation of your signature for those documents.
How does the artistic smoothing engine work?
The fdmGTP engine applies quadratic curve algorithms to your drawing input. This removes the "shaky" look often found in digital pads, resulting in a smooth, high-quality handwritten appearance.
Is my signature saved on your servers?
No. Privacy is our priority. Your signature is processed entirely in your browser's local memory. We never upload, store, or see your signature coordinates.
Can I customize the color and thickness?
Absolutely. You can toggle between professional ink colors (Black, Blue, Red) and adjust the pen stroke thickness to match the requirements of your specific document.
What format is the signature exported in?
Your signature is exported as a high-resolution transparent PNG. This allows you to overlay it on any PDF, Word document, or image without a messy white background.
Does this work on mobile and tablets?
Yes. The signature pad is fully responsive and optimized for touchscreens. It works exceptionally well with a stylus or Apple Pencil for maximum precision.
Do I need to register to download my signature?
No registration is required. We follow a "no-login" philosophy. You draw, you download, and you move on with your day—zero friction involved.
