PDF4.dev

HTML to PDF API for developers + 24 free PDF tools. Create templates, preview live, render

Visit PDF4.dev

PDF4.dev is a PDF generation API for developers. It lets you create pixel-perfect PDFs from HTML templates. You design templates visually or in code using a Monaco-based editor with live preview, define dynamic fields with Handlebars variables, and generate PDFs via a simple REST API call from any language (TypeScript, Python, Go, Rust, PHP, cURL). The rendering pipeline uses headless Chromium (Playwright) for accurate CSS support including flexbox, grid, and web fonts. PDF4.dev also provides a built-in MCP server so AI agents like Claude, ChatGPT, and Cursor can generate PDFs with natural language. Free browser-based PDF tools (merge, split, compress, convert) process files entirely client-side for privacy.
