PDFSign - Sign any PDF in 60 seconds. Offline. No Java. No plugins.

Every PDF signing tool I tried needed Java, browser plugins, or cloud uploads. I built PDFSign.in to fix that. Native Windows app. Plug in your USB certificate token. Sign in 60 seconds. Or embed a signature/stamp image — no token needed. ✅ 100% offline — files never leave your PC ✅ Batch-sign hundreds of PDFs ✅ No Java. No plugins. .NET 10. ✅ RFC 3161 timestamp + PDF encryption 30-day free trial. Now on Microsoft Store.

Hey PH! 👋 I'm Hiral, maker of PDFSign.in. I built this out of pure frustration. I run a business that deals with a lot of government documents, and every time I needed to digitally sign a PDF with my USB certificate, I had to wrestle with Java versions and browser plugins that broke every few months. So I spent a few months building a proper native Windows app. No Java. No plugins. Just install, plug in your USB token, and sign — done in under a minute. It also works without a USB token — you can embed a handwritten signature or rubber stamp image directly on the PDF. Useful for quick internal documents. Just got onto the Microsoft Store this week after clearing their certification. Would love your feedback — especially from anyone who signs PDFs for legal, accounting, or government work. What features are you missing? Happy to answer any questions below. 🙏
