html to pdf api

If you want to convert HTML to PDF via an API, here are the main options:

1. Use a PDF conversion service

Popular APIs:

• PDFShift
• DocRaptor
• PSPDFKit
• CloudConvert
• ConvertAPI
• Browserless / headless Chrome based services

Typical flow:

1. Send HTML/CSS (or a URL)
2. API renders it in a browser engine
3. Returns a PDF file or download link

2. Example request

Many APIs work like this:

curl -X POST https://api.example.com/v1/convert \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "html": "<html><body><h1>Hello PDF</h1></body></html>",
    "format": "pdf"
  }'

3. Python example

import requests

url = "https://api.example.com/v1/convert"
headers = {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json"
}
data = {
    "html": "<html><body><h1>Hello PDF</h1></body></html>"
}

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

with open("output.pdf", "wb") as f:
    f.write(response.content)

4. Things to look for

• Support for CSS styling
• Page size / margins
• Headers and footers
• JavaScript rendering
• Remote assets like images and fonts
• Security if converting user-generated HTML

5. If you want to build your own API

You can create one using:

• Node.js + Puppeteer
• Python + Playwright
• wkhtmltopdf wrapper
• Headless Chrome

• a Node.js example
• a Python/FastAPI example
• or a self-hosted solution
