PDFik Reviews & Product Details

PDFik is an asynchronous PDF generation API for developers and engineering teams. Send a public URL, raw HTML or an EN 16931 invoice XML, receive a job ID, and get an HMAC-signed webhook the moment the PDF is ready — polling endpoints exist for environments that cannot receive callbacks. Rendering runs on sandboxed headless Chromium, so modern CSS, web fonts and JavaScript-heavy pages come out pixel-accurate. Who it is for Software and SaaS teams that generate documents from their own applications — invoices, receipts, statements, reports, tickets — at any volume; teams replacing self-hosted wkhtmltopdf or Puppeteer/Chromium rendering with a managed API; and European teams that need Factur-X / ZUGFeRD hybrid e-invoices from the invoice data they already have. Typical users are developers, CTOs and technical founders at startups through enterprise engineering teams. How it works 1. POST a job with a URL or HTML (plus optional page size, margins, headers/footers, wait conditions), or POST your EN 16931 invoice XML to the e-invoice endpoint. 2. Receive a job ID immediately; rendering runs asynchronously on a queue with autoscaled workers. 3. Get an HMAC-signed webhook when the job finishes, or poll the job status endpoint. 4. Download the PDF from a controlled link; generated documents are guaranteed deleted within 24 hours. Key capabilities - URL and HTML rendering on sandboxed Chromium (Playwright), one isolated browser context per job. - Factur-X / ZUGFeRD e-invoicing on every plan: PDFik embeds your EN 16931 XML into a PDF/A-3 hybrid invoice (all five profiles, MINIMUM through EXTENDED); the XML is validated against the official XSD before any quota is spent, and output is validated with veraPDF and Mustangproject. - Signed webhooks on every plan, including Free: HMAC signatures, automatic retries with backoff, and a dead-letter queue — a lost callback surfaces on PDFik's side instead of failing silently on yours. - Free test mode: pass "test": true to exercise the full pipeline (statuses, webhooks, signatures, downloads) without spending quota. - Files up to 150 MB on every plan, including Free. - Authenticated rendering (basic/bearer credentials for URLs behind auth) on Pro and above; credentials are attached only to same-origin requests and encrypted end to end while queued. - Two published billing meters per plan — rendered PDFs and generated gigabytes, counted separately; downloads never debit quota; every limit is on the pricing page. - Privacy by default: 24-hour guaranteed deletion of generated documents; per-job credentials AES-256-GCM encrypted. - Security: Chromium sandbox enabled, SSRF protection (private networks, cloud metadata, file:// blocked at request and render time), API keys hashed at rest with optional IP allowlists, TLS everywhere, optional two-factor authentication on the dashboard, RFC 7807 error responses with stable error codes. - Developer experience: official typed SDKs for JavaScript/TypeScript, Python and Java; public OpenAPI specification; copy-paste curl quickstarts; an open-source CLI with a wkhtmltopdf compatibility mode; a no-account sandbox on the homepage that performs a real render; public status page with live probes. - Dashboard: API key lifecycle, usage and limits by both meters, job history, webhook settings and delivery log, billing via Stripe.
