This is a demonstration site — for demo purposes only. PDF Workbench is currently invite-only.
Browser-based PDF suite

Every PDF tool, one workspace.

28 tools — edit, merge, split, convert, OCR, compare, sign and archive. 20 of them run entirely in your browser, so the document never leaves your machine. Every edit is attested and auditable.

The difference

Free PDF sites, or a real workspace.

Most people upload sensitive documents to random websites. Here's what changes with PDF Workbench.

Without PDF Workbench

  • Uploading confidential client documents to random free websites
  • No record of who changed a statement, or when
  • Paying per-page for basic operations like merge and split
  • Rebuilding a paper book by hand because pages cannot be renumbered

With PDF Workbench

  • Most work happens in your browser — nothing leaves the machine
  • Every edit carries a verifiable attestation and audit entry
  • One subscription for every PDF operation your practice needs
  • Annexure numbering, page organising and PDF/A archival built in
Tools

28 tools, six categories, one workspace

Everything from a quick merge to archival conversion and version comparison — with the audit trail a regulated practice needs.

Images ↔ PDF

Turn scans and photos into a PDF, or export pages as images.

PDF/A Archive

Security

Protect, sign and remove sensitive content

Compliance

Evidence, provenance and audit trail

Verify

Confirm a PDF was produced here and is unaltered.

Bates Numbering

Stamp sequential legal reference numbers across a set of documents.

20 of the 28 run entirely in your browser — the document never reaches a server. The remaining 8 (Compress, OCR, Repair, Convert, PDF/A Archive, Unlock, Image to text, Office to PDF) need server-side engines, so the file is uploaded over TLS, processed on India-resident infrastructure, and deleted immediately afterwards. Every tool tells you which kind it is before you start.

Not another online converter. A professional workspace.

Built for teams that handle sensitive documents — financial statements, legal contracts, audit reports.

DPDP and GDPR native — granular consent, data export, and right to erasure built in
Trust & Compliance

Built for regulated industries

PDF Workbench is designed from the ground up to meet the compliance requirements of financial services, legal, audit and healthcare teams.

DPDP Act, 2023

India's Digital Personal Data Protection

  • Explicit consent capture before any data processing
  • Purpose limitation — data used only for stated purpose
  • Right to erasure — delete all personal data on request
  • Data Principal rights portal for access and correction
  • Breach notification workflow within 72 hours
  • Data fiduciary obligations enforced at application layer

GDPR

EU General Data Protection Regulation

  • Lawful basis tracking for every processing activity
  • Data processing records (Article 30) maintained automatically
  • Right to access, rectification, portability, and erasure
  • Data Protection Officer workflow and contact page
  • Privacy by design and by default architecture
  • Cross-border transfer safeguards — data stays in-region

SOX Compliance

Sarbanes-Oxley Act controls

  • Immutable, hash-chained audit log on every action
  • Append-only database triggers — logs cannot be altered
  • Role-based access controls with least-privilege enforcement
  • Document retention policies with legal hold capability
  • Complete chain of custody for every document version
  • Segregation of duties across processing and approval

Compliance is not a feature — it's the foundation

Every line of code, every database table, every API endpoint is built with compliance as a first-class constraint. Audit logging is immutable and hash-chained. Consent is tracked per-action. Data retention is policy-driven. Access controls are enforced at the database layer, not just the UI.
