PDFBolt

About PDFBolt

PDFBolt is a REST API that converts HTML, URLs, and templates into PDFs using headless Chromium. It offers three conversion modes: direct (PDF returned in the response), sync (downloadable URL), and async (signed webhook callback). Templates support Handlebars syntax and AI generation from prompts and reference files, alongside a gallery of ready-to-use templates.

The API includes privacy controls such as redaction of HTML and template data after processing, automatic PDF deletion after 24 hours, and EU-based processing. It supports direct upload to S3-compatible buckets including AWS, Backblaze B2, MinIO, Wasabi, and DigitalOcean Spaces. Print production features include PDF/X-4, PDF/X-1a, CMYK conversion, and ICC color profiles.

Official SDKs are provided for Node.js, Python, and PHP, with REST examples for Java, C#, Go, Rust, and cURL, plus a Postman collection. It is aimed at developers and businesses needing production-grade PDF generation. A free plan offers 100 documents per month with no credit card required.
