Powerful Capabilities

Everything You Need for Enterprise PDF Generation

Built on modern headless browser engines tuned specifically for high-throughput, low latency, and pixel precision.

Full Modern CSS3 & JS

Supports modern web standards including Flexbox, CSS Grid, custom web fonts, SVG graphics, Chart.js diagrams, and complex layouts.

Headers, Footers & Margins

Embed dynamic page numbers, timestamps, custom logo headers, and configurable margins on each page with zero CSS hassle.

Zero Data Retention

Your document data is processed in ephemeral memory and immediately streamed back. We never store your sensitive customer invoices or data.

Custom Watermarks

Add transparent background text or graphic watermarks ("PAID", "CONFIDENTIAL", company seal) across any page dynamically.

Sub-Second Conversion

Clustered cloud instances with warm browser pools deliver sub-second generation times even during high volume concurrency spikes.

Custom Page Dimensions

Choose standard sizes (A4, A3, Letter, Legal) or define exact custom width/height millimeter dimensions for receipts and labels.

Simple Integration

How the HTML to PDF API Works

Generate professional documents in 3 straightforward steps with any HTTP client or backend framework.

1. Send HTML / URL

POST your HTML string, template variables, or target URL with your API key in the Authorization header.

2. Cloud Rendering

Our cloud rendering cluster executes CSS/JS, computes pagination, applies headers/footers, and produces a crisp PDF.

3. Stream or Save

Receive the binary stream directly in your response to save to S3, email to customers, or serve directly in browser.
