The Engine for Your Document Workflows
Discover the building blocks for creating, managing, and delivering documents at any scale. Our service is more than just an HTML to PDF endpoint; it’s a complete document automation platform. We provide tools that cover the entire document lifecycle, from our flexible template editor and dynamic data-merging capabilities to multi-tenant workspaces and secure delivery options. Use these features to construct reliable, end-to-end document workflows that grow with your business.
Seamlessly merge JSON data with your templates to generate dynamic documents. Our engine supports nested data structures, loops for rendering lists or table rows, and conditional logic, allowing you to handle even the most complex data schemas with ease.
Generate PDFs from various sources to fit your workflow. Convert a raw HTML string to a PDF, or provide a URL and let our service render the page into a high-fidelity PDF document. This is perfect for generating reports from web pages or archiving online content.
Automate the process of filling out existing PDF forms. Programmatically populate text fields, checkboxes, and radio buttons with data from your sources. You can also flatten the form fields to make the document read-only after it is generated.
Built for scale, our API handles everything from single document generation to large batch jobs. For time-intensive tasks, use our asynchronous endpoints to queue generation requests without blocking your application’s primary thread, ensuring a smooth user experience.
Empowers your customers to create and manage their own templates directly within your application, reducing your team’s support load and offering a powerful layer of customisation. This is the ideal solution for SaaS platforms that require personalised document branding and layouts for each customer.
Optionally store your generated documents in our secure, ISO 27001 certified cloud storage. Alternatively, configure your account to deliver documents directly to your own AWS S3 bucket, giving you complete ownership and control over your data.
For organisations with stringent security, data residency, or compliance requirements, we offer a self-hosted version. This solution is designed for enterprises in sectors such as finance, healthcare, and government that cannot utilise multi-tenant SaaS solutions.
Choose Your Perfect Integration Path
Whether you're building a sophisticated application with custom code or automating workflows on a low-code platform, we provide a seamless integration path that fits your specific needs. We believe in meeting you where you work, so you can connect to the PDF Generator API in the way that makes the most sense for you and your project.

“As a bank, we operate in a highly regulated environment with especially high attention to customer data protection. As an example, it was a requirement for us not to have the service process customer data outside of the European Economic Area, which the PDF Generator API was able to meet by setting up a dedicated deployment for us.”

Why Katana decided to buy instead of build?
“On a strategic level, we have decided to utilise best-in-class solutions already available on the market and utilise our resources only to integrate them into our everyday operations. That way, we can focus on our strengths and core business, which is, after all, production. As a service provider, we can offer our clients the best possible solutions tailored to their needs. Whenever a client uses an integration we offer, they can be assured that it has undergone a rigorous validation process, and we are putting our seal of approval on it. No sub-par integration will pass through.”

The Strategic Decision
Should You Build or Buy Your PDF Generation Solution?
For many development teams, the initial impulse is to build. It seems straightforward enough: install a library, write some code, and generate a PDF. However, creating a truly robust, scalable, and secure document generation service is a project in itself, fraught with hidden complexities and long-term costs that can divert significant resources from your core business objectives. Before your team commits to building a solution from the ground up, it's crucial to look beyond the initial lines of code and consider the total cost of ownership (TCO) and the strategic implications of that choice.
Infrastructure & Scalability: The Performance Bottleneck
Ongoing Maintenance: The Never-Ending Task
Security & Compliance: The Non-Negotiable Requirement
