Best Practices & Key Recommendations
- When drawing with a mouse, use a moderate pen thickness (2–3px) for smooth, natural signature lines.
- On mobile and touchscreen devices, use your finger or stylus directly on the draw pad for maximum handwriting fidelity.
- Upload a transparent PNG signature for quick reusable signing across multiple documents.
Troubleshooting & Common Issues
- Signature appears pixelated when enlarged: Draw your signature at larger dimensions on the canvas pad before placing it on the base image.
- Signature background covers document text: Use the Draw or Type modes, or ensure your uploaded signature file is a transparent PNG.
