DocRaptor
HTML-to-PDF API powered by Prince XML, producing high-quality, CSS-compliant PDFs from HTML templates, particularly strong for complex paged media with headers, footers, page numbers, and print CSS.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
API key auth. HTML/CSS submitted for PDF rendering — sanitize user-supplied HTML to prevent SSRF or data exfiltration. SOC2 Type II. Generated documents may contain sensitive data.
⚡ Reliability
Best When
You need the highest-quality, most spec-compliant HTML-to-PDF conversion with full CSS print media support, particularly for long documents with headers/footers/page numbers.
Avoid When
Cost is a primary concern, you need JavaScript-rendered content, or your documents are simple and don't require Prince's superior CSS support.
Use Cases
- • Generating professional invoices, contracts, and reports with precise print layout
- • Legal document and compliance report generation requiring exact pagination control
- • Ebooks and long-form documents with complex cross-references and table of contents
- • Template-driven document generation from HTML with CSS print stylesheets
- • High-quality PDF output where pixel-perfect rendering of complex layouts is required
Not For
- • High-volume PDF generation at low cost (Prince licensing makes DocRaptor premium-priced)
- • PDFs from JavaScript-heavy SPAs where data is loaded dynamically (use Browserless instead)
- • Simple one-page PDFs without complex layout needs (use wkhtmltopdf or a lighter tool)
- • Real-time PDF generation with sub-second latency requirements
Interface
Authentication
API key in request body or HTTP Basic Auth header. Test mode available with 'YOUR_API_KEY_HERE' for development (produces watermarked PDFs).
Pricing
Significantly more expensive per document than browser-based alternatives, but the Prince-based rendering quality justifies the cost for professional documents. Document limits on paid plans.
Agent Metadata
Known Gotchas
- ⚠ Monthly document limits — production agents must track consumption to avoid hitting limit
- ⚠ External resources (images, fonts, CSS) must be accessible from DocRaptor's servers — local/private URLs fail silently
- ⚠ JavaScript in HTML is NOT executed by default — DocRaptor uses Prince, not a browser; data must be server-side rendered
- ⚠ Base64-encode images or use absolute public URLs to avoid resource loading failures
- ⚠ Test mode documents have watermark — test key is hardcoded string, not dynamic
- ⚠ PDF/A and PDF/X compliance modes available but require specific HTML/CSS constraints
