THUMB IMPRESSION
Resize thumb impression for exam form upload
Upload a photo of your real inked thumb impression — the tool whitens the paper background, darkens the ink so the ridges are clear, auto-crops, and resizes it to the exact pixel and KB size required by NDA, CRPF, state police, and defence exam forms. Select your exam for auto-preset, or enter custom dimensions.
Which exams require thumb impression upload?
Always verify thumb impression requirements from the official recruitment notification — dimensions and formats change across batches.
How to take a good thumb impression for exam forms
Use a clean ink pad and press your left thumb firmly but evenly on white A4 paper.
Scan the paper using your phone camera — natural daylight, no shadows.
Crop the image close to the ink impression, leaving a small white border.
