Convert URL/HTML to PDF API

What it does

HTML to PDF Render turns a public URL or raw HTML into a PDF binary, with optional PDF merging in the same request. Send either url or html, choose a page_size of A4, Letter, or Legal, and include merge_urls when you want to append existing PDFs after the rendered output.

Use it when you need server-side document generation from web content: invoices, reports, receipts, archived pages, or print-ready snapshots of dynamic HTML. The response is a binary PDF, so you can stream it, store it, or pass it into your own file pipeline without parsing intermediate data.

Because the input is plain HTML or a reachable URL, it fits workflows that already render content in the browser or template layer but need a stable PDF artifact for download, email, or recordkeeping. The merge step is useful when a generated cover page or statement should be combined with supporting PDFs before delivery.

HTML to PDF Render keeps the contract simple: one request body, predictable page sizing, and a PDF result.
