If you've ever struggled with DSC signing, this will feel familiar…

Why most DSC signing tools fail — and how PDFSign fixes it

The old way
  • ✕ Install Java, fight with browser plugins
  • ✕ Upload your confidential PDF to a stranger's server
  • ✕ Error: "Token not detected" — restart, try again
  • ✕ Different tool for every government portal
  • ✕ Sign one file at a time — manually, every time
  • ✕ Expired certificate? No warning — signing fails silently
VS
The PDFSign way
  • ✓ Open app → load PDF → sign. Done in 10 seconds
  • ✓ 100% offline — your files never leave your PC
  • ✓ Auto-detects all major DSC tokens instantly
  • ✓ One tool for GeM, CPPP, Income Tax and MCA21 filings
  • ✓ Bulk sign hundreds of PDFs in one click
  • ✓ Expired cert warning before you sign — no surprises

If you've ever worried about sending confidential documents to a cloud service, you're not alone…

Why cloud PDF signing tools put your documents at risk — and how PDFSign fixes it

The cloud way
  • ✕ Upload confidential documents to unknown cloud servers
  • ✕ No real PKI signature — just an image stamp, legally weak
  • ✕ Per-document or per-seat pricing — costs spiral fast
  • ✕ Session expires mid-signing — no offline fallback
  • ✕ GDPR exposure: vendor stores your documents indefinitely
  • ✕ Browser extension breaks after every update
VS
The PDFSign way
  • ✓ 100% offline — your documents never leave your PC. Ever.
  • ✓ Real PKI digital signature — cryptographically verifiable
  • ✓ One-time purchase — no per-document fees, ever
  • ✓ Works without internet — sign anywhere, anytime
  • ✓ Air-gap secure — zero cloud exposure, GDPR-friendly
  • ✓ Desktop app — stable, fast, no browser dependency

(not theory)

All DSC Tokens Supported

Works with HyperPKI HYP2003, ePass 2003/3003, Proxkey, WD Pro, Feitian, Watchdata — any token from a CCA-licensed CA whose Windows driver is installed.

Sign without DSC using stamp image

Upload your handwritten signature or company stamp as an image and embed it visually on any PDF — no DSC token required for this mode.

Bulk PDF Signing

Sign multiple PDFs at once — sign hundreds of PDFs in one click. Perfect for tender submissions, GST invoices, certificates, and bulk document workflows. Learn about bulk PDF signing →

PDF Security

Restrict printing, editing, and copying of your signed PDF. Set a document open password or owner permissions — enforced by Adobe Acrobat.

Click exactly where you want your signature

Click anywhere on the PDF page preview to place your signature exactly where you want it — no guessing row/column positions.

RFC 3161 Timestamp

Embed a trusted timestamp from a government-recognised TSA server — proves the document was signed at a specific point in time, even after cert expiry.

Offline & Private

Your documents never leave your PC. Signing happens entirely on your machine — no uploads, no cloud, no third-party server sees your files.

Government Compliant

Standard Adobe PKCS#7 signatures for GeM, CPPP, NIC e-Procurement, MCA21, Income Tax and DGFT filings. Signed files verified on GeM on 18 July 2026.

PDFSign vs other DSC signing tools

Not all PDF signing tools are equal — especially when your documents must be accepted on Indian government portals.

Common questions

Everything you need to know before you sign your first PDF.

Most tools rely on Java applets, browser plugins, or cloud servers — all of which break with Windows updates, Chrome security changes, or internet issues. PDFSign reads your certificate straight from the Windows certificate store and signs through Windows' own crypto layer, with no browser or Java in the middle. That's why it works reliably.

PDFSign runs on Windows 10 and Windows 11 (64-bit). It requires .NET 10 Runtime, which the installer downloads automatically if not already present on your machine.

No. Signing happens 100% on your machine. Your documents never leave your computer. We have no access to your files, your DSC token, or its private key — ever.

PDFSign signs with your USB DSC token and writes a standard Adobe detached PKCS#7 signature (SHA-256) — the format Acrobat and Indian portals read. Signed files were verified on GeM on 18 July 2026; CPPP, NIC e-Procurement, MCA21, Income Tax and DGFT are what customers file with but we have no dated test result for them, so tell us if one ever rejects a file. Note: PDFs signed with only a stamp or handwritten image (without a DSC token) are not digitally signed and may not be accepted on government procurement portals that require a valid Class 2 or Class 3 DSC.

PDFSign signs with the X.509 certificate on your USB token and writes a standard Adobe detached PKCS#7 signature (/adbe.pkcs7.detached, SHA-256) that Adobe Acrobat verifies anywhere in the world. The legal weight comes from your certificate and the law where you file, not from the software — so we don't claim eIDAS, E-SIGN or any other statute on PDFSign's behalf. Two specifics worth knowing: PDFSign does not add eIDAS or ICP-Brasil policy identifiers to the signature, and EU qualified signatures additionally need a Qualified Certificate from a Qualified Trust Service Provider (QTSP). Our dated compatibility testing is on GeM (18 July 2026); we have not tested non-Indian government portals, so ask us before you commit to one.

Completely GDPR-safe. All signing happens entirely on your local Windows PC — your PDF is never uploaded to any server. We have zero access to your documents, your private key, or your signing PIN. The only data we collect is optional: your email address (if you enter it during purchase) and anonymous download counts. No document content ever leaves your machine.

PDFSign works with all major USB DSC tokens used in India — HyperPKI (HYP2003), ePass 2003/3003, Proxkey, Feitian, WD Pro, Watchdata, and any token from a CCA-licensed Indian CA whose Windows driver is installed.

PDFSign works with USB tokens that install a Windows driver — including SafeNet iKey, Thales Luna USB, HID ActivKey, Gemalto IDPrime, Feitian ePass, WD Pro and WatchData, from CAs worldwide. Install your token's Windows driver; once its certificate shows up in the Windows certificate store, PDFSign detects and uses it.

No. PDFSign is a native Windows desktop app. It requires no Java, no browser plugin, no admin rights, and no internet connection to sign PDFs.

Yes. If your DSC token has an organisation certificate, PDFSign shows it as a signing option alongside your personal certificate. The visible signature stamp on the PDF page shows your name and signing date. The organisation name is visible inside the signature certificate details — anyone who opens the Signatures panel in Adobe Acrobat Reader will see your name, organisation, and issuing CA in the validation panel.

Yes. PDFSign includes a Signature & Stamp Image mode. You can upload a PNG/JPG of your handwritten signature or company rubber stamp and embed it visually on any PDF page — no USB token required for this mode.

Point PDFSign at a folder, enter your PIN once, and it signs every PDF in that folder automatically — applying the same certificate, signature position, and settings to all files. Signed copies are saved to your chosen output folder.

Yes. PDFSign lets you set PDF permissions — restrict printing, editing, and content copying — and optionally add a document open password. These restrictions are enforced by Adobe Acrobat and compatible viewers.

An optional RFC 3161 timestamp embeds a cryptographic proof of when the document was signed, obtained from a trusted Timestamp Authority (TSA) server. That lets a reader see the signature was made while your certificate was still valid, instead of relying on the clock on your PC. It is not long-term validation (LTV): PDFSign does not embed revocation data (OCSP/CRL) or a /DSS dictionary, so a verifier still fetches revocation information itself. The timestamp is also best-effort — if the TSA is unreachable, PDFSign tells you and completes the signature without one.

Yes. PDFSign offers two placement modes: a 9-position grid (top-left to bottom-right) or click-anywhere on the PDF page preview to drop the signature stamp at a precise location.

Solo licences (Monthly, Annual, Lifetime) are for 1 Windows device. Team licences cover 5 PCs — ideal for CA firms, law offices, and corporate teams. You can transfer a solo licence to a new PC by contacting support.

The team plan (Annual ₹3,499/yr or Lifetime ₹13,999) covers 5 Windows PCs under one shared licence key. Each user in your firm gets their own copy of the app, activated with the same key. Ideal for CA firms, law offices, and tender-filing teams.

Yes. After licence activation (which requires internet once), the app works fully offline. PDF signing, batch processing, stamp image mode — all work without any internet connection.

PDFSign warns you before you sign if your certificate has expired, so you're never caught off guard. If you had RFC 3161 timestamps on previously signed documents, those signatures remain valid. You'll need to renew your DSC from your CA to sign new documents.

Yes. PDFSign works on any Windows PC worldwide. If you hold an Indian DSC token issued by a CCA-licensed CA, you can sign Indian government documents from anywhere — UAE, UK, USA, Canada, Australia, or any other country. The software has no geo-restriction.

PDFSign has a built-in Verify function. You can also open the PDF in Adobe Acrobat Reader and check the Signatures panel — it will show the certificate chain, signing time, and validity status. Signed PDFs also display a blue ribbon in Adobe when the signature is valid.

Yes. Every download includes a free evaluation. You can evaluate PDFSign for up to 30 days or 100 signed PDFs (whichever comes first) before choosing a subscription.

The purpose of the free evaluation is to let you verify that PDFSign works perfectly with your USB DSC token, PDF documents and signing workflow. If you regularly sign large numbers of PDFs, you can continue without interruption by upgrading to a paid plan.

Your documents, settings, saved signatures and templates remain safely stored on your computer. Only new PDF signing requires an active subscription.

PDFSign includes a free evaluation — up to 30 days or 100 signed PDFs — so you can fully evaluate it before buying. Because of that, all licence purchases are final and non-refundable, except where required by applicable law. See our Refund Policy for details.
