Frequently asked questions
Why does a notary application need a specific signature format?
Legal and e-filing portals often have strict technical limitations. They typically require small file sizes (often under 50KB or 100KB) and specific file types (like JPEG) to ensure the documents are manageable and standardized.
How do I take a good photo of my signature?
Use plain, unlined white paper. Use a thick black or blue pen. Ensure there is good lighting (daylight is best) to avoid shadows, and take the photo straight on.
Is my signature safe?
Absolutely. Your signature is a highly sensitive biometric identifier. This tool processes the image entirely locally in your web browser. It is never uploaded to any server.
