Is the downloaded signature PNG truly transparent?

Yes! When you download as Transparent PNG, the background is completely transparent, allowing you to paste your signature onto any contract, Word document, Google Doc, or PDF seamlessly.

Can I take a photo of my physical paper signature and extract it?

Yes! Use the 'Paper Signature' tab to snap a photo or upload an image of your handwritten signature. DocTool automatically removes the paper background and converts your ink into a crisp, transparent vector-grade signature.

Is a digital signature created here legally valid?

Electronic signatures created online are legally recognized under the US ESIGN Act, UETA, and EU eIDAS regulations for standard business agreements, contracts, and internal approvals.

Are my handwritten signatures stored or saved on DocTool servers?

Never. All drawing canvas strokes and image extractions happen strictly in your local device memory. Your signature is never transmitted to any external server.
