Batch eSign PDF is developed by 3thousand30.

What happens on your device

Batch eSign PDF processes selected PDF files locally on your Windows device. Signature image capture, placement, PDF stamping, certificate signing operations, output validation, progress reporting, and cleanup all happen on the PC running the app.

Your PDF contents are not uploaded to 3thousand30 servers. Superimposed signing needs no certificate or network access at all. USB-token signing talks only to your own Windows certificate store and CNG provider — never to a 3thousand30 server or any third-party signing service.

Signature images

Signature profiles (drawn, typed, or uploaded images) are stored locally under your Windows user profile’s application data folder. They are ordinary local image files, not secrets, and are never uploaded.

Certificates and PINs

Certificate selection, private-key access, and PIN entry are handled entirely by Windows and your certificate/token’s own driver. Batch eSign PDF never sees, stores, or logs your PIN. It does not persist which certificate you used beyond the current session’s settings.

Source and output files

The app reads only the PDF files or folders you select. It writes signed copies to the output folder you choose and never overwrites an input file directly — it writes a temporary candidate, validates it, and only then promotes it using the app’s collision rules.

Signed, encrypted, and malformed PDFs

Already-signed, encrypted, and malformed PDFs are skipped by default when processing them would be unsafe, ambiguous, or would invalidate an existing signature. Skipped files remain in their original location and are not modified.

Windows and the Microsoft Store may independently collect installation, purchase, licensing, reliability, or crash information under Microsoft’s own terms.

Documentation, support, Microsoft Store, and website links open in your browser. Those destinations are governed by their own privacy policies and browser settings.
