About This Tool
The Signature & Stamp Chroma Ink Optimizer functions as a professional high-fidelity ink purifier.
Signatures or corporate seals captured on phones often suffer from yellow paper tint, uneven shadows, and page wrinkles. Pasting them directly onto contract PDFs looks amateur.
This tool separates the Alpha channel based on luminance and color space. It completely bleaches paper backgrounds while sharpening stamp red (Chroma Ink) and handwriting black. The result is a premium, transparent PNG stamp carrying genuine ink textures.

Frequently Asked Questions
Standard chroma-keying often makes signature stroke details look blocky and pixelated. Our algorithm isolates only white/yellow background noise and smooths the ink borders.
