Frequently Asked Questions
Why do government exam portals reject signatures?
Portals reject signatures when the file size is outside the allowed range (usually 10 KB to 20 KB) or dimensions don’t match 140 × 60 pixels. This tool guarantees both limits are met.
How do I make the signature background white?
Enable the 'Enhance ink contrast' option. The tool boosts black ink and brightens the background paper to pure white.
What should the signature dimensions be?
Most Indian exam portals recommend 140 pixels wide by 60 pixels high (aspect ratio of 7:3) or 3.5 cm × 1.5 cm.
Is the signature uploaded to any server?
No. All processing is 100% client-side in your browser. Your signature remains completely private.
