Why Use JSON to PDF Renderer?
Creating PDF documents programmatically has traditionally required complex libraries and verbose code. The JSON to PDF Renderer simplifies this by letting you define your entire document layout using a declarative JSON schema. Simply describe your document structure — headings, text blocks, tables, lists, and layout containers — and get a pixel-perfect PDF in seconds.
This approach is ideal for developers building automated reporting pipelines, generating invoices and certificates on-the-fly, or prototyping document layouts without writing backend code. The JSON spec format is based on the open-source json-render standard, making it portable and easy to integrate with any tech stack.
Everything runs directly in your browser — no data is sent to any server. Your documents remain completely private and secure. Choose from pre-built templates for common document types or craft custom layouts from scratch using the full component library.
Frequently Asked Questions
What JSON format does this tool expect?
The tool uses a component-based JSON schema inspired by the json-render standard. Each node has a "component" name (e.g., Heading, Text, Table) and a "props" object with configuration. Nodes can have "children" arrays for nesting. Click any template to see the format in action.
Can I create multi-page documents?
The PDF generator automatically handles page breaks when content exceeds a single page. You define margins and page size in the Page component's props, and the renderer takes care of pagination.
What page sizes are supported?
The tool supports A3, A4, A5, Letter, and Legal page sizes in both portrait and landscape orientations. Set these in the Page component's size and orientation props.
Is my data secure?
Absolutely. All processing happens entirely in your browser using client-side JavaScript. No JSON data or generated PDFs are sent to any server. Your documents remain completely private.
Can I include images in my PDFs?
The HTML preview supports images via the Image component with a src URL. Note that PDF generation currently focuses on text-based content (headings, text, tables, lists) for maximum reliability across all browsers.
