PDFSpark Pricing 2026

PDFSpark is a free productivity tool that offers 6 key features including No API key and no signup — POST directly to the endpoint, Chromium via Playwright: full JavaScript, CSS3 and web font rendering, URL-to-PDF and raw HTML-to-PDF, for invoices, reports and certificates. PDFSpark is an HTML-to-PDF and URL-to-PDF conversion API with an unusual property for a hosted service: it requires no API key and no signup at all. Requests POST directly to the endpoint. Rendering runs on Chromium via Playwright, which is the same engine that renders the modern web, so JavaScript executes, CSS3 applies, web fonts load and dynamic content resolves before the page is captured — the failure mode that makes older wkhtmltopdf-based pipelines produce documents that do not match the browser. The project positions itself explicitly as a wkhtmltopdf alternative for that reason. Two input modes are supported: point it at any public URL, or send raw HTML with inline CSS and JavaScript, which is the mode that matters for generating invoices, reports and certificates from a template. Beyond conversion it merges multiple PDFs, splits and extracts specific pages, and handles page format, margins, orientation, text and image watermarks with configurable font size, opacity, rotation and colour, document metadata, header and footer templates, and custom CSS injection. Output can be password-protected with AES-256 encryption. The endpoint is SSRF-protected, which matters when the service will fetch an arbitrary URL on a caller's behalf.
