Excellent App, Outstanding Developer Support
Cert Sign Pro is an excellent tool for professional PDF digital signatures. It’s reliable, practical, and has become a valuable part of our business workflow.
What truly sets it apart is the developer’s responsiveness. We reported a technical interoperability issue, and the developer investigated it thoroughly, implemented a fix, and included our test case in future regression testing.
Also, you gotta love an app that requests no additional data in 2026.
Excellent software backed by a developer who genuinely cares about quality. Highly recommended!

The one PDF signing tool I’ve ever needed. No Acrobat B.S., no shady online tools. This works brilliant with my PFX certificate.
