pdfs.build for Web Apps

PDF template engine with a REST API and AI template editor

A PDF template engine and rendering API for developers and teams that generate documents programmatically. Define a template once with dynamic variables, POST JSON data to the API, and get a pixel-perfect PDF back in milliseconds.

What you get

• AI template editor: describe the document in chat and get a template with typed variables and a live preview.

• REST API and SDKs: one call renders a template with your JSON data, and webhooks tell your app when a job finishes.

• Typst rendering engine: tables, page breaks, running headers and footers and multi-page layouts behave the way print expects.

• Word import: upload an existing DOCX file and turn it into a reusable template.

• MCP server: let Claude Code, Cursor or your own agent create, test and publish templates for you.

• Embeddable editor: drop the template designer into your own SaaS so your customers design their own invoices, reports, contracts and certificates.

• Template gallery: start from ready-made invoices, reports, certificates, statements and letters.

Pricing
