HTML wasn't built for Print

Most PDF APIs are headless browsers that render HTML and export the result.

But browsers are designed for screens, not print.

HTML wasn't built for Print

Most PDF APIs are headless browsers that render HTML and export the result.

But browsers are designed for screens, not print.

Layouts easily break

Long paragraphs, extra table rows and awkward page boundaries break your document.

Print features are missing

Basic document features like page numbers, tables of contents and running headers become code you have to build and maintain.

Endless glue code

Translating and hand-wiring data into rigid templates.

Headless browsers are fragile

Cold starts, memory spikes, rendering quirks, latency, and random crashes become part of your PDF pipeline.

From AI Markdown and JSON to a finished PDF

Papermill takes markdown and data, applies your template, and returns a production-ready PDF.
