Convert HTML to PDF API

About Convert HTML to PDF API

The HTML to PDF API converts HTML content into PDF files, accepting input as a remote URL, a base64-encoded payload, or a direct file upload. Output can be returned either as a downloadable PDF binary or as a signed link (a data URI pointing to the generated file), depending on which endpoint is used. Several endpoints support an optional landscape orientation parameter, and download variants allow the output filename to be specified.

The API exposes 6 POST endpoints covering combinations of input method (URL, base64, file upload) and output method (binary download or signed link). File uploads are capped at 100MB total per request, with a note to use the URL-based endpoint for larger files. It is intended for generating PDFs such as invoices, reports, receipts, archived snapshots, or printable versions of existing web pages.

The service is hosted on ApyHub, is at version 1.0.0, and is listed as a verified provider on the platform.
