Sign thousands of PDFs in one go, not one by one.
Bulk PDF Signer digitally signs invoices, contracts, certificates and Form-16s at scale — with DSC token, PFX or Aadhaar-based signatures, fully compliant and fully automated.
Bulk Signer
Bulk Signer is a fast and secure digital signing solution that allows you to sign multiple PDF documents in one click using one or more DSC tokens. Save time, improve productivity, and automate bulk document signing for businesses, CAs, and government organizations.
One platform, three ways to sign at scale.
Whether it's manual bulk runs, fully automated pipelines, or API-driven signing baked into your own software — pick the mode that fits your workflow.
Bulk Signer Software
Sign thousands of PDFs in a few clicks.
Point the software at an input folder, choose your certificate — USB token, PFX or Aadhaar-based — and let it sign every document inside, placing each signature exactly where your template defines.
Built for invoices, agreements, certificates and reports, with timestamping and full signing logs on every run.
Set it once, let it sign itself.
Automated PDF Signing watches a folder or queue and signs new documents the moment they land — no manual trigger, no missed batch, no waiting.
Certificate-based signatures guarantee authenticity while the workflow runs entirely unattended.
Signing, built into your own systems.
