Protect Your Legal Signature From Cloud Storage Harvesting

Your handwritten signature is used on bank cheques, PAN cards, tax filings, and legal deeds—uploading raw signature photos to unknown remote servers is a serious identity-theft risk.

PixelKit crops your signature 100% inside your browser’s local RAM. Click the Crop button on your uploaded card to drag the 2:1 box snugly around your pen strokes (leaving ~10% clean white margin on all four sides), and optionally set 20 KB in Stage 3 if uploading to an exam portal.

Frequently asked questions

How tight should I crop my signature for SSC, IBPS, or UPSC?
Crop close enough that your signature fills roughly 75%–85% of the horizontal 2:1 box, leaving a thin, clean white paper border without touching any pen loops.
Can I both crop my signature AND compress it to 10KB–20KB?
Yes! Either enable 10–20 KB Range in Stage 3 right here, or jump to our pre-configured Signature Resizer 10KB to 20KB.
Why should I sign on unruled white paper with black ink?
Ruled notebook lines fail automated portal background checks, and black ballpoint/gel ink retains highest contrast after JPEG quantization.
Can I export a cropped signature as PNG for Word or PDF documents?
Yes—select PNG in Stage 1 for lossless crisp strokes when placing your signature onto digital documents.
