Product Information
Everything you need to know about
Microlink HTML to PDF API.
Do I need to manage my own Headless Chrome instances?
No. Microlink acts as a fully managed, "backendless" browser service. We maintain the underlying Chromium infrastructure, manage the instance pool, and handle edge caching.
You simply make a REST API call and receive a structured JSON payload or a PDF document directly the easiest way to convert any URL to PDF without maintaining
Puppeteer
or Playwright
on your own servers.Is there a free tier for the HTML to PDF API?
Yes. Our free HTML to PDF API tier provides 50 requests per day with unrestricted access to all document generation features, including custom paper sizes, margin controls, and CSS injection.
No credit card, account creation, or API key is required to start developing. Try it instantly in the PDF playground or point your code at the endpoint and begin converting.
What paper sizes and formats are supported?
Our URL to PDF API supports all standard paper formats: A0 through A6, Letter, Legal, and Tabloid. You can switch between portrait and landscape orientation with a single parameter.
Fine-tune margins in cm, mm, or px, set custom scaling, and extract specific page ranges for precise document output.
Can I interact with the DOM or run scripts before generating the PDF?
Absolutely. Our web to PDF API provides complete browser control. You can execute arbitrary JavaScript via our functions integration, or use native parameters for page preparation scroll, click, wait for selectors, and inject custom CSS before PDF generation.
It is built to handle complex, dynamic SPA rendering and produce pixel-perfect PDF documents from any web content.
What is your uptime SLA and expected latency?
We guarantee enterprise-grade reliability with a 99.9% uptime SLA. Every request runs in an isolated browser instance to guarantee security and avoid shared-state leaks. Check real-time availability on the status page. Need to generate PDFs from authenticated pages? We support that too.
For latency: PDFs are distributed via Cloudflare's 240+ edge locations, meaning cached responses are delivered in milliseconds. Our optimized Chromium pool handles cold starts efficiently for consistent performance. See our troubleshooting guide for common questions.
What output options are available?
You can generate PDFs in any paper format with configurable margins, orientation, and scaling. Page ranges let you extract exactly the content you need.
You can request a direct PDF binary via the embed parameter, or a JSON payload that includes the PDF URL alongside metadata and performance timings. Need screenshots too? Our API also supports screenshot capture.
How quickly can I integrate this HTML to PDF service into my stack?
In minutes. Visit our documentation for interactive playground examples, official SDKs (Node.js, Python, Ruby, Go), and copy-paste code snippets for any language.
