ABOUT THIS TOOL
Why use this tool?
Mobile photos of paper signatures often have yellowish lighting, shadows, or gray backgrounds that fail portal checks. Our contrast booster turns paper paper-white while keeping ink crisp.
Frequently Asked Questions
Why does my signature get rejected on government portals?
Portals reject signatures if the background is shaded/dark or if the file weight is outside the 10 KB – 20 KB range. Our tool cleans both problems instantly.
How does the background enhancement work?
The contrast filter increases the brightness threshold of non-ink pixels to pure white (#FFFFFF), giving the appearance of a clean flatbed scanner scan.
What format should I upload?
Take a clear photo with your phone in JPG or PNG, upload it here, and download the optimized official signature.
