Batch digital signing.
100% offline.

Signatrix: Sign hundreds of PDFs in minutes, without cloud.

Signatrix — digital signing made easy
Core principle: Your documents stay on your machine. No cloud upload, no server, complete confidentiality.

The problem

Paper signing is slow, unpredictable, and hard to track.

Before Signatrix

Stacks of paper, rooms full of folders

Thousands of documents printed in multiple copies, carried between offices, waiting for each signer in turn.

No visibility on where the document is

Is it on Maria's desk? Did the courier deliver it? No one knows. Workflows stall.

One missing signer blocks everything

One person on leave means the entire batch waits. Documents pile up, deadlines slip.

The solution

Signatrix turns hours of signing into minutes.

After Signatrix

Sign hundreds of PDFs in one click

Select a folder, click Sign. Signatrix processes the entire batch in parallel — 20 to 60 documents per minute.

Full workflow visibility

Each signer gets an email notification. You see exactly who signed, who is next, and who is absent — in real time.

Works on your machine, without internet

No cloud, no uploads, no subscriptions to external signing platforms. Documents stay inside your organization.

Capabilities

Everything you need to sign at scale

Built for notaries, accountants, lawyers, and public institutions that handle large volumes of documents.

Batch signing — entire folders

Select a folder and sign all PDFs in one click. Hundreds of documents in minutes, each with a precisely placed visible signature.

Precise coordinate placement

Drag-and-drop signature placement on a live PDF preview. Coordinates saved per signer profile — consistent on every document.

PKCS#12 and PKCS#11 hardware tokens

Supports .p12/.pfx certificate files and USB hardware tokens (eToken, SafeNet). Full PAdES-standard signing via pyhanko.

Replace signature tables in seconds

Need to add or replace a signer in a ministry document? Signatrix removes the old signature block and rebuilds it — across all documents at once.

Multi-signer serial workflow

Define a signing chain: each signer receives an email notification, signs, and passes the document to the next. Absentees handled automatically.

Signature verification

Inspect and validate existing signatures in any PDF: signer name, reason, location, timestamp, certificate chain details.

Sign on every page, or selected pages

Apply signatures to all pages, odd/even pages, or a custom range (e.g. 1,3,5–8). Useful for contracts requiring a signature on each page.

PDF Tools — 9 built-in utilities

Merge, split, rotate, watermark, anonymize, extract text/images, edit metadata, encrypt/decrypt — all without leaving Signatrix.

Anonymize sensitive data

Automatically redact emails, IBANs, phone numbers, CNPs, passport numbers, bank cards and more — 11 regex patterns, international + Romanian.

Encrypt and protect PDFs

AES-128 encryption with user and owner passwords. Decrypt any protected PDF you have the password for — locally, without cloud.

Bulk signing

247 documents signed. 4 minutes elapsed.

No document limit per session

Process an entire year's archive in one run. Signatrix signs in parallel threads — no waiting.

Speed benchmark visible in the log

After each session, Signatrix shows documents/minute — a concrete number you can share with management.

USB hardware token supported

Qualified certificates on eToken, SafeNet or other PKCS#11 devices sign the full batch with a single PIN entry.

Hardware tokens

Your qualified certificate. Your USB token. No cloud involved.

eIDAS-compliant qualified signatures

Works with certificates from CertDigital, certSIGN, GlobalSign, DigiCert, Certum and all eIDAS-accredited providers.

PIN entered once per session

Enter your PIN once at the start of a signing session. Signatrix handles the rest — no repeated prompts per document.

Token protection built-in

Signatrix detects incorrect PINs after the first attempt and stops — preventing token lockout from repeated failures.

Signature tables

Signer changed? Rebuild the entire table in seconds.

Common in government and public institutions

Ministries, agencies and public bodies often require exact signer lists. One replacement used to mean reprinting everything.

Paste one line, Signatrix finds the rest

Copy a row from the document, paste it as a marker. Signatrix removes everything from that point to the end and rebuilds.

Applied to the entire batch at once

One operation updates all documents in the folder — not one by one.

From raw documents to signed PDFs in three steps

Step 1: Prepare

Drop your source files (.doc, .odt, .rtf) into the Prepare tab. Signatrix converts them to PDF and appends your signature page automatically.

Step 2: Sign

Select your signer profile, enter your certificate password or PIN once, and click Sign. Signatrix processes the entire folder in parallel.

Step 3: Verify

Open any signed PDF in the Verify tab to inspect the signature chain — certificate details, timestamp, integrity status.

Done — documents ready to submit.

Used in production by real teams

Real results from organizations that replaced paper signing with Signatrix.

" We had 2,600 to 4,000 cadastral survey files every season — 2 to 3 pages each, printed in 3 or 4 copies, signed by hand by 7 people. Now the entire commission signs the full batch digitally in one session. What took days takes an afternoon. "


Cadastral Commission

Cadastral Commission

Public institution, Romania

" In government agencies, you cannot just swap a signer — you have to reprint and redistribute the entire signature table across all documents. With Signatrix, we mark the old table, Signatrix removes it and rebuilds it everywhere. A 20-minute job that used to take two days. "


Document Control Office

Document Control Office

Government agency, Romania

" Generating PNG images from Word documents or scanned text used to require multiple tools. Now we do it in one step — and we can sign all of them at once. The workflow went from chaotic to predictable overnight. "


Administrative Department

Administrative Department

Regional public authority, Romania

" We had documents sitting on someone's desk for a week with no one knowing. The signing workflow was completely opaque. With Signatrix, every step sends a notification, every signer knows their turn. Nothing gets lost. "


Legal Team

Legal & Compliance Team

Mid-size company, Romania

" We needed signatures on every page of the contract — with the signer's coordinates fixed in a specific corner. No other tool handled this natively. Signatrix did it out of the box. "

FAQ

Frequently Asked Questions

Does Signatrix upload my documents anywhere?

No. Signatrix runs entirely on your machine. Your documents, certificates, and PIN codes never leave your computer. There is no cloud component.

What certificate types are supported?

PKCS#12 files (.p12, .pfx) — issued by any Certificate Authority — and PKCS#11 hardware tokens (eToken, SafeNet, etc.). Compatible with qualified certificates from CertDigital, certSIGN, GlobalSign, DigiCert, Certum and others.

Is the digital signature legally valid?

Yes, if you use a qualified certificate from an eIDAS-accredited Trust Service Provider. Signatrix applies PAdES-format signatures, accepted in all EU member states. The EU Trusted List is at eidas.ec.europa.eu/efda/tl-browser.

How many documents can I sign at once?

There is no technical limit. Free: up to 10/month. Pro: 200/month. Business: unlimited. Signing speed is typically 20–60 documents/minute depending on file size and hardware.

Can I delegate my token to someone else to sign on my behalf?

No. A digital signature has the same legal weight as a handwritten one. Unauthorized delegation constitutes forgery. Each person must sign personally with their own certificate.

What happens if someone sees my PIN?

Change your token PIN immediately using the software provided by your certificate issuer. If you cannot, contact the issuer to block and reissue the token. Signatures applied before the incident remain valid.

What is a SEAL and how is it different from a signature?

A SEAL (electronic seal) is the organizational equivalent of a stamp — applied by a legal entity, not an individual. A qualified eIDAS SEAL has legal force across the EU and is typically applied at the end of a signing workflow to certify the final document.

What operating systems are supported?

macOS (Apple Silicon and Intel) and Windows 10/11. LibreOffice is required for the document preparation pipeline (converting .doc/.odt to PDF).

How does license activation work?

After purchase, you receive a license key by email. Enter it once in the application Settings. The key is tied to your device and verified against our servers. Grace period of 30 days offline. If you change computers, use the recovery option on signatrix.io.
