Frequently asked questions
What size should a signature be for exam forms?
Usually 140 × 60 px for bank exams and 300 × 120 px for NTA exams, between 10 and 30 KB. Open your exam's own page for the exact numbers.
My signature photo has a grey background. Can I fix it?
Yes. Turn on the paper clean-up: it whitens the background and darkens the ink before compressing.
Which pen should I use?
A black or dark blue ball pen on plain white paper. Sign larger than the box; the tool scales it down.
Is my signature uploaded?
No. It is processed in your browser and never leaves your device.
