Executable browser example

PDFs stay in your hands.

Create, inspect, modify, compose, preview, and download PDFs as browser-owned bytes, on the page or across a module Worker boundary.

01 / Input

Bring byte assets

Run the original end-to-end low-level and Recipe workflow, with optional font and image assets.

Use a Worker for untrusted documents. Parsing and image decoding are synchronous and can consume significant CPU and memory. Keep inputs and expected outputs bounded; this example is intended for modest documents (for example, under 25 MB input and 50 MB output).

02 / Output

Inspect the result

Ready. No bytes leave this page.

Structured run report
Run the workflow to see parse-back assertions and document summaries.
