▣ FILE CONVERSION

Convert HTML to PDF API

What it does

HTML to PDF Converter turns HTML sources into PDF output. Send a base64-encoded HTML payload, a file upload, or a remote HTML URL, and get back either a downloadable PDF binary or a signed PDF link.

Use the /base64/link, /file/link, and /url/link endpoints when you want a URI you can hand off to another system or store for later retrieval. Use the /base64/download, /file/download, and /url/download endpoints when your application needs the PDF bytes directly. The file and URL variants also support a landscape query parameter, and the file download endpoint lets you set an output filename.

This is a practical fit for generating invoices, reports, receipts, and archived web pages from HTML you already render in your application. If your template engine or CMS already produces HTML, you can convert that content into a PDF without adding a browser-based rendering flow on your side.
