PolyDoc - HTML to PDF & Screenshot API

A REST API for HTML to PDF and screenshot generation, with best-effort PDF/A and PDF/UA output you can verify before it ships. - High-fidelity PDF Generation: Convert HTML strings or URLs into accurate PDFs with full support for modern JavaScript and CSS. - Archival & E-Invoicing: Generate best-effort PDF/A archival output for long-term retention, and create Factur-X and ZUGFeRD hybrid e-invoices with embedded XML data. - Accessible PDFs: Create best-effort tagged PDFs (PDF/UA-1) for screen reader compatibility. - Verification You Can Enforce: An optional VeraPDF check on PDF/A or PDF/UA output; if a document does not pass, the API returns an error instead of a non-conformant file. - Security & Control: Protect documents with password encryption, add watermarks, and configure PDF outlines and metadata. - Layout Customization: Utilize standard or custom page sizes, margins, orientation, headers, footers, and page ranges. Supports CSS Paged Media tools like Paged.js. - Screenshot Capture: Generate pixel-perfect screenshots in PNG, JPEG, or WebP formats from HTML or URLs, with options for full-page or clipped captures and custom viewports. - Developer-Friendly Features: Inject CSS and JavaScript, wait for specific selectors, control rendering media types, and block ads/trackers. - Templates: Design and manage HTML templates with a built-in editor, using Liquid syntax for dynamic data integration. - Webhooks & Cloud Storage: Receive conversion results asynchronously via webhooks and upload generated files directly to your cloud storage (AWS S3, Google Cloud, Azure Blob Storage, etc.) using presigned URLs. - Dashboard & Playground: Manage API keys, test conversions live, monitor usage with analytics, and track quotas. - Privacy-Focused: Stateless architecture, isolated rendering, and EU data residency ensure your data is processed securely and never stored after conversion. - Sandbox Mode: Test integrations risk-free with watermarked sandbox conversions.
