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.
