Why JSON and not a normal form?

Document templates each have different fields — there is no static set we could put in this tool's form. JSON is the lowest-friction generic interface. The /docs/ page is what you want for an interactive UI.

Can I pre-fill a template and then download from this tool?

In v1 you supply JSON manually. A "share link" pre-fill is on the roadmap.

Are the files uploaded?

No — template lookup, body rendering, and PDF assembly all run in your browser.

Document Template to PDF

Pick any of our 60+ document templates, supply the field values as JSON, and get a clean printable PDF.

How does the Document Template to PDF work?

Render any of our 60+ document templates straight to a PDF without going through the per-template /docs page first. Pick a template from the dropdown, drop in a JSON object of field values matching the template's field names, choose paper size, and get a clean printable PDF. Useful for scripted bulk-generation, AI-pipeline chaining, or anyone who already knows the template fields and wants to skip the form UI. To discover field names: visit /docs/<slug> in your browser, watch the form, and read the input names — they match the JSON keys.
