Tips for the Best Transparent Signature
- •Use a dark pen — Black or dark blue ink gives the best contrast against white paper. Light colored pens may lose detail after background removal.
- •Sign on clean white paper — Avoid lined paper, receipts, or colored paper. A plain white background gives the cleanest removal.
- •Good lighting — Even lighting prevents shadows that can be mistaken for part of the signature. Natural daylight works best.
- •Crop before uploading — Crop the image to show mostly your signature with minimal extra space for best AI detection.
- •High resolution — A clear, high-res photo ensures the signature edges stay crisp after background removal.

Yes. The AI detects the signature regardless of ink color — black, blue, red, or any other color. The ink color is preserved in the output.
Can I resize the signature after removing the background?
Yes. After downloading the transparent PNG, use our image resizer to adjust the dimensions for your specific document.
What format should I save my signature in?
