PDF DSC-TSA Bulk Signer 2.0, developed by PrajnaBytes International Private Limited | RatioJuris.
Free software under the GNU General Public License v3.0 or later.
Put a visible stamp on every page you choose, and secure the whole PDF with one digital signature (DSC) or one trusted timestamp seal (no DSC needed).
What's new
- Visible stamps on every chosen page, secured by one DSC signature, or by an RFC 3161 timestamp seal (DigiCert, Sectigo, GlobalSign, SSL.com, Entrust)
- Stamp designer with saved designs, signature images, a Classic two-column layout and Hindi (Devanagari) text
- "Repeat on all pages" when placing stamps
- After signing, a Save window asks where to save the signed PDF. Your original is never overwritten. You can then open the PDF or its folder.
- File dialogs start in Documents or the last folder used
- The certificate list shows only personal signing certificates; expired DSCs and unplugged tokens are shown as unavailable
- Tested with a real DSC USB token (HyperPKI HYP2003) on Windows 11, with and without a timestamp
- Automatic update checks from GitHub, with signed update information
- Now licensed under the GPL (1.0 used a proprietary EULA)

Please note
- Installing on Windows: Windows asks "Do you want to allow this app to make changes to your device?". Click Yes. The portable version needs no administrator rights.
- Upgrading from 1.0: the 2.0 installer removes version 1.0 automatically.
- Open and verifiable: this is independent open-source software; the complete source code is public. Commercial code-signing certificates are a recurring paid service that this project does not currently use, so on first launch:
- Windows may show "Windows protected your PC". Click More info, then Run anyway.
- macOS may block the app. Open System Settings → Privacy & Security and click Open Anyway (on macOS 14 and older, right-click the app and choose Open).
- Linux and macOS DSC tokens work through the token maker's PKCS#11 library. This has not yet been tested with real tokens on those systems. Timestamp seals work without a token.
