Spec score 8.1 #14 of 41 in HTML to PDF APIs

What it is

PDF API converts HTML templates and JSON data into PDFs through a cloud REST API. Developers can submit raw HTML or reuse dashboard templates with Handlebars-style variables, loops, and conditionals. Page size, orientation, margins, headers, and footers are configurable, while Chromium rendering supports modern CSS including Flexbox, Grid, and custom properties. Listed uses include invoices, receipts, contracts, financial reports, shipping labels, and tickets. The maker says a persistent Chromium pool and Rust backend generate documents in under 300ms. Webhooks report generation, deletion, and approaching quota limits, with authenticity checked through the X-PDF-Signature header. Generated files use temporary URLs and are removed when a URL expires, by default after 24 hours, or when deleted. Sandbox requests do not count toward quota, but sandbox files are watermarked and purged after one hour. The service is EU-hosted and GDPR compliant. Plans include Free at free for 500 PDFs monthly and paid plans from €15/mo.
