PDFik - 2026 Pricing, Features, Reviews & Alternatives

PDFik is an asynchronous PDF generation API for engineering teams that need reliable page-to-PDF rendering without operating a browser fleet.

HOW IT WORKS

Submit a public URL or raw HTML via POST, receive a job ID immediately, and get an HMAC-signed webhook when the PDF is ready. Polling endpoints exist for environments that cannot receive callbacks. Output is downloaded from a controlled link; generated files are guaranteed deleted within 24 hours.

RENDERING

Sandboxed headless Chromium driven by Playwright, one isolated browser context per job (no shared state between jobs, downloads and popups disabled). Modern CSS, web fonts and JavaScript-heavy pages render pixel-accurate. Authenticated rendering (basic/bearer credentials for URLs behind auth) is available on Pro and above; credentials are attached only to same-origin requests and encrypted end to end while in transit through the queue.

E-INVOICING

POST /einvoice-to-pdf accepts UN/CEFACT Cross-Industry Invoice XML (EN 16931) and returns a PDF/A-3 hybrid with the XML embedded as factur-x.xml — all five Factur-X / ZUGFeRD profiles, MINIMUM through EXTENDED. The XML is validated against the official XSD before any quota is spent, and output is validated with veraPDF (PDF/A-3b) and Mustangproject. The same einvoice option attaches your XML to a URL or HTML render, so an existing invoice template keeps working unchanged.

DELIVERY

Webhooks are HMAC-signed and available on every plan, including Free. Failed deliveries are retried automatically with a growing backoff and then parked in a dead-letter queue — never lost silently. Secret rotation with an overlap window (Pro and above) lets receivers verify signatures without downtime.

BILLING & LIMITS

Two published meters per plan: rendered PDFs and generated gigabytes, counted separately. Downloads never debit quota. Files up to 150 MB on every plan. Rate limits and concurrency ceilings are documented per plan; the API answers with RFC 7807 problem details and stable error codes.

TEST MODE

Pass "test": true to run the full pipeline — statuses, webhooks, signatures, downloads — without spending quota. A no-account sandbox on the homepage performs a real render before you sign up.

SECURITY

Per-job browser isolation with Chromium's sandbox enabled; SSRF protection blocks private networks, cloud metadata endpoints and file:// URLs at request and render time; API keys are hashed at rest and support IP allowlists; per-job credentials are AES-256-GCM encrypted; TLS everywhere; optional TOTP two-factor authentication on the dashboard; a public status page with live probes.

INTEGRATION

Official typed SDKs for JavaScript/TypeScript (npm), Python (PyPI) and Java (Maven Central), a public OpenAPI specification for the generation endpoints, copy-paste curl quickstarts, and an open-source CLI with a wkhtmltopdf compatibility mode.
