Signature Validator

Validate e-Sign in PDF, No Invalid Signature Errors

About This Tool

It is a common frustration: You download your Aadhaar card, Pan card, or Caste Certificate, but instead of a valid signature, you see a confusing "Yellow Question Mark" or "Validity Unknown". This doesn't mean your document is invalid. It simply means your phone or browser (like Chrome/Edge) doesn't have the specific technical files to recognize the government's digital signature. Our tool solves this instantly. We verify the digital signature against the official standards and provide you with a **Verified Copy**. This copy has the "Signature Valid" status permanently embedded, so it shows the Green Tick on any device—whether it's your mobile phone, a cyber cafe computer, or a printout. No more right-clicking, no more technical configuration.

Why Your Digital Signature Says 'Not Verified' (And How to Fix It)

We've all been there. You urgently need to print your Aadhaar card, Caste Certificate, or Income Certificate for a job application or admission. You download the PDF, open it, and your heart sinks. Instead of a valid green tick, you see a confusing yellow question mark that says 'Validity Unknown'.

This little symbol can cause big problems. Local printing shops often refuse to print it, or officials reject the document thinking it's not original.

So, is your document invalid?

Absolutely not. Your document is 100% authentic. The problem isn't with your file; it's with the software viewing it. Most PDF viewers (especially on mobile phones and basic computer browsers) don't have the specific technical files needed to recognize the government's digital signature.

How do we fix it?

You could spend hours installing drivers and configuring Adobe Acrobat on a PC, but that's complicated. Or, you can use this tool.

We verify the signature's authenticity securely and then generate a Verified Copy of your document. This copy works everywhere—on your phone, at the cyber cafe, and on any printer. The green tick becomes a permanent part of the document, so you never have to worry about 'Right Clicking' and 'Validating' ever again.
