Why VaultPDF?
Why teams choose VaultPDF over general-purpose PDF tools - covering data sovereignty, deterministic output, and enterprise integration.
The Problem with Traditional PDF Generation
Most PDF tools were built for simple documents. When enterprises need to generate high-fidelity, data-driven PDFs at scale - inside a secure tenant - the options fall short.
| Approach | Key Limitation |
|---|---|
| Puppeteer / Headless Chrome | Fragile HTML-to-PDF conversion, inconsistent layout across environments |
| DocRaptor / HTML2PDF services | Your data leaves your tenant to a third-party server |
| Word / SSRS / Crystal Reports | Legacy tooling, not designed for JSON-driven automation |
| Power Automate PDF connectors | Limited formatting, no structured layout engine |
VaultPDF was designed specifically for the enterprise scenario none of these tools handle well.
What Makes VaultPDF Different
1. No Data Egress
VaultPDF runs entirely inside your Microsoft Azure environment. Your document payloads, template definitions, and rendered PDFs never leave your tenant.
Zero external dependencies at runtime
VaultPDF has no outbound HTTP calls during rendering. Every byte of your data stays within your tenant boundary.
2. Deterministic, Schema-Driven Rendering
Templates are defined as structured JSON - not WYSIWYG. The same payload always produces the same output. No browser quirks, no font substitution surprises, no layout drift between environments.
3. Built for Automation
VaultPDF is designed to be called from Power Automate flows, Azure Logic Apps, or any HTTP client. Drop a JSON payload in, get a PDF out. No human-in-the-loop required.
4. Enterprise Layout Engine
First-class support for the constructs enterprise documents actually need:
- Multi-section layouts with independent columns and spacing
- Hierarchical tables with grouping, subtotals, and row-level formatting
- Signature zones compatible with DocuSign, Adobe Sign, and Dropbox Sign
- Approval pages with QR verification and tamper-evident metadata
- Automatic pagination with repeating headers and footers
5. Predictable Per-Tenant Pricing
VaultPDF is subscription-based and licensed per tenant - not per document, per user, or per API call. There is no metered usage or consumption-based billing that scales unpredictably with volume. One tenant subscription covers your entire organization, with no third-party SaaS dependency sitting between your data and your output.
Who Is VaultPDF For?
VaultPDF is the right fit when:
- You are operating in a regulated industry (finance, healthcare, legal, government) and cannot send document data to external services
- You generate documents that require consistent, auditable formatting - invoices, contracts, reports, certificates
- You want to automate document generation from Power Automate or Azure without building a custom rendering engine
- You already run on Microsoft 365 and want to keep your PDF infrastructure inside the same trust boundary
What VaultPDF Is Not
- Not a PDF editor. VaultPDF generates PDFs from structured data. It does not read, annotate, or modify existing PDF files.
- Not a visual template designer. Templates are JSON definitions. There is no drag-and-drop builder.
- Not a document management system. VaultPDF renders and returns PDFs. Where you store or distribute them is up to your workflow.
What is VaultPDF?
VaultPDF is a cloud-native document rendering engine that converts structured JSON data into polished PDFs entirely within your Azure environment. No third-party SaaS. No data leaving your tenant.
