Sign Thousands of PDFs with Your DSC — In One Operation

neoSigner is a Windows batch PDF signing software for signing hundreds or thousands of documents — invoices, contracts, offer letters, compliance reports — in a single operation using your Digital Signature Certificate. CA firms, HR teams, finance departments and procurement offices use it daily.

Template Mode fixes the signature at an exact page position — ideal when all your documents share the same format (like a standard invoice template). Text Mode searches for a unique word or phrase on each page and places the signature above or below it — useful when document layouts vary slightly.

Yes. neoSigner is a fully offline desktop application. Once installed and licensed, it requires no internet connection to sign documents — suitable for air-gapped environments and strict network policies. An internet connection is only needed if you use the optional auto-email feature.

neoSigner works with any CCA-certified USB DSC token (eMudhra, SignX, Capricorn, and others) as well as PFX/P12 certificate files. You can register multiple certificates and switch between them for different signers.

There's no hard limit — neoSigner has been tested with batches of 10,000+ PDFs. USB tokens typically sign at 2-3 seconds per document; a batch of 1,000 PDFs usually completes in under 30 minutes.

Yes — neoSigner signs using your existing Digital Signature Certificate (USB token or PFX file); it doesn't issue certificates itself. If you don't have a DSC yet, we can set you up with one — see our DSC pricing below.
