JSignPdf at a glance

Checked 15 Oct 2026

JSignPdf (3.2.1, 28 Sep 2026) is a Java desktop app with installers for Windows, macOS (Apple Silicon) and Linux, plus a batch command line. It signs PDFs you hold with PKCS#12 keystores or PKCS#11 tokens and smartcards, adds RFC 3161 timestamps and OCSP/CRL data, and can produce PAdES signatures through the bundled EU DSS engine. It only signs locally: no sending to other signers, tracking or templates. Dual-licensed MPL-2.0 / LGPL-2.1.
