Glossary
- Electronic Signature
- A handwritten signature drawn on a tablet or mouse, saved as a digital image. Used by placing it as an image on PDF or Word documents.
- Digital Signature
- A cryptographic mechanism that verifies document authenticity. Unlike electronic signatures, it provides tamper detection. This tool creates graphical signatures, not cryptographic ones.
- Canvas API
- HTML5 browser 2D drawing API. Captures mouse and touch input as coordinates to draw lines in real time.
- Bezier Curve
- A mathematical method for drawing smooth curves using control points. `quadraticCurveTo()` recreates natural handwriting strokes.
- Pointer Events
- A Web API that unifies mouse, touch, and pen input. Allows the same code to handle handwriting on any device.
- Transparent PNG
- A PNG image with a transparent background. When placed on a document, the background does not interfere.
- Google Fonts
- A free web font service by Google. Used to load cursive fonts like Dancing Script.
- Clipboard API
- A browser API for copying text or images to the system clipboard. Uses `navigator.clipboard.write()` to copy images.
FAQ
- Q.Is the generated signature legally valid?
- This tool creates a graphical signature image only. It does not carry the legal force of a cryptographic digital signature. Suitable for informal documents and internal use.
- Q.Is my name sent to any server?
- No. All processing happens locally in your browser via the Canvas API. No data is sent externally.
- Q.How do I undo a stroke?
- Click the "Undo" button to remove the last stroke. Use "Clear All" to start over.
- Q.Can I make the background transparent?
- Yes. Select "Transparent" in the background settings to export a PNG with an alpha channel.
- Q.How many fonts are available in text mode?
- 5 Latin fonts (Dancing Script, Great Vibes, Sacramento, Allura, Pacifico) and 2 Japanese fonts (Yomogi, Zen Kurenaido), 7 in total.
- Q.Does it work on smartphones?
- Yes. The Pointer Events API supports touch drawing on any device.
- Q.How do I add the signature to a PDF?
- Save the transparent PNG and use Adobe Acrobat or a similar PDF editor to insert it as an image.
- Q.Can I copy the signature to my clipboard?
- Yes. The "Copy to Clipboard" button copies the PNG image, which you can paste directly into Word or Google Docs.
