PDF (Portable Document Format) is the global standard for contracts, invoices, application forms, and official documentation.

Why Client-Side Security Matters for PDF Editing
Unlike traditional PDF tools (such as Smallpdf, iLovePDF, or Adobe Acrobat Web) that require sending your file over the internet to a third-party server, MyDigitSign runs on WebAssembly and client-side JavaScript. Your file stays inside your computer or smartphone at all times. This provides total privacy compliance for GDPR, HIPAA, and corporate security guidelines.
