What are UPSC's signature specifications?

UPSC requires a signature image of 3.5cm × 1.5cm, JPG/JPEG format, file size 20–300 KB, on white paper in black ink.

What are SSC's signature specifications?

SSC requires signature image 4cm × 2cm (approximately 140×60 px at 96DPI), JPG format, file size 10–20KB, white background.

Can I use a digital signature created on screen?

Yes. You can upload a signature drawn digitally. For creating a brand-new digital signature, use our Advanced Digital Signature tool.

My signature has a yellow/grey background — will it be fixed?

Yes. The AI automatically detects and replaces non-white backgrounds with pure white, which is required by most exam portals.

The file size is still too large after resizing — what do I do?

Use the quality slider to reduce the JPEG compression level. Most signatures compress well below 20KB at 85% quality.
