why people still pay for Smallpdf Pro
People still pay for Smallpdf Pro because the visible editor is reproducible, but reliable rendering and legally defensible signature workflows are not a casual side project. The recurring cost buys format edge cases, fonts, rendering, encryption, signatures, evidence, retention, storage, backups, and legal requirements, not just the visible interface. If none of that applies to you, any pick above saves $144 a year.
