Build Once Process Anything.

A single platform for HTML rendering, image processing, and PDF workflows — delivered through simple, production-ready APIs.

Core Processing Endpoints

H2I exposes a focused set of external APIs for common media processing workflows, designed to be predictable and safe for production use.

HTML Endpoints

Render HTML into images or PDFs with controlled viewport and layout settings, producing consistent output for emails, reports, previews, and dynamic content generation in production environments.

Image Endpoints

Transform images through resizing, format conversion, optimization, cropping, and watermarking, with predictable results suitable for high-volume and production-grade visual workflows.

PDF Endpoints

Manipulate PDF files by merging, splitting, compressing, rotating pages, and extracting content, enabling reliable document processing across automated and integrated systems.

Tools Endpoints

Analyze files to extract metadata, validate inputs, and perform file-based processing actions through structured API requests designed for predictable behavior and production use.

Why Developers Choose H2I

H2I is built for teams that need reliability, clarity, and scale — without trading control or transparency.

Production-First Architecture

Every request is validated, controlled, and executed with production safety in mind. Timeouts, concurrency limits, and usage tracking are enforced automatically to prevent unpredictable behavior.

Clean & Predictable APIs

H2I avoids fragmented or experimental endpoints. Each API follows a consistent structure, making integration easy and reducing long-term maintenance costs.

No Infrastructure Overhead

There are no render engines, workers, queues, or schedulers for you to manage. You send a request — H2I handles execution and delivery.

Built for Automation

H2I integrates cleanly into CI pipelines, CMS platforms, backend services, and automated workflows where consistent behavior, repeatable requests, and predictable results are required.

Secure Output Delivery

Processed files are returned as structured responses with controlled output URLs, allowing safe integration with applications, storage systems, and delivery layers.

Transparent Usage Control

Rate limits, quotas, and usage behavior are enforced consistently so teams can plan usage, monitor activity, and scale with confidence.

One Platform, Many Workflows

From simple image optimization to HTML rendering and document processing, H2I provides a unified access layer that exposes multiple processing capabilities through consistent, production-ready APIs.

How H2I Works

H2I provides a simple, secure way to turn inputs into processed outputs, whether you are using the API or working directly through the H2I website.

Choose How You Use H2I

You can use H2I directly through its website pages for quick tasks, or integrate it into your application using HTTP APIs for automated and large-scale processing.

Select an Action

Choose the endpoint and action that defines how your input should be processed — such as rendering HTML, resizing an image, or manipulating a PDF.

Send Input

Send HTML, images, or documents either by uploading files through the H2I interface or by submitting structured requests from your backend or scripts.

Receive Results

H2I processes the request and returns structured results, including secure URLs to ready-to-use output files that can be stored, delivered, or reused immediately.

Call the API with a Simple HTTP Request

H2I works with any language or framework that can send HTTP requests. Below are real examples using the Image Processing API.

💻

filename.js

curl -X POST "https://api.h2i.dev/v1/image" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "action=resize" \
  -F "width=800" \
  -F "format=webp" \
  -F "image=@input.jpg"

🐘

filename.php

<?php
$ch = curl_init("https://api.h2i.dev/v1/image");

curl_setopt_array($ch, [
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_POST => true,
  CURLOPT_HTTPHEADER => [
    "Authorization: Bearer YOUR_API_KEY"
  ],
  CURLOPT_POSTFIELDS => [
    "action" => "resize",
    "width" => "800",
    "format" => "webp",
    "image" => new CURLFile("input.jpg")
  ]
]);

$response = curl_exec($ch);
curl_close($ch);

echo $response;

📄

filename.js

import fetch from "node-fetch";
import FormData from "form-data";
import fs from "fs";

const form = new FormData();
form.append("action", "resize");
form.append("width", "800");
form.append("format", "webp");
form.append("image", fs.createReadStream("input.jpg"));

const res = await fetch("https://api.h2i.dev/v1/image", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_KEY"
  },
  body: form
});

const data = await res.json();
console.log(data);

🐍

filename.js

import requests

url = "https://api.h2i.dev/v1/image"
headers = {
    "Authorization": "Bearer YOUR_API_KEY"
}

files = {
    "image": open("input.jpg", "rb")
}

data = {
    "action": "resize",
    "width": 800,
    "format": "webp"
}

response = requests.post(url, headers=headers, files=files, data=data)
print(response.json())

Real World Use Cases

User Upload Optimization

H2I can sit behind user upload flows to automatically normalize and optimize images before storage or delivery. Uploaded files are processed through the Image API to apply resizing, format conversion, and optimization, ensuring consistent quality without client-side logic.

Performance-Oriented Websites

H2I helps performance-focused websites generate lightweight, optimized assets for faster loading and consistent visuals. Images can be resized and compressed through the API during build or request time, reducing payload size without manual optimization.

Content Platforms & CMS

Content platforms can use H2I to process images and documents as part of editorial workflows. Media uploads are standardized, PDFs can be transformed or extracted, and assets are prepared for publishing without custom processing pipelines.

E-Commerce Media Pipelines

H2I enables e-commerce systems to generate consistent product images in multiple sizes and formats from a single source file. This ensures uniform visuals across listings, thumbnails, and marketing assets with automated API-driven processing.

Automated Backend Jobs

H2I fits into scheduled or event-driven backend jobs that process images, PDFs, or HTML outputs automatically. Systems trigger API requests, receive predictable results, and handle batch processing without manual intervention or infrastructure management.
