Free PDF API - Merge, Split, Compress PDFs Programmatically

Complete PDF toolkit API: merge, split, compress, rotate, watermark, extract text, add page numbers. Free tier available.

A PDF API is a powerful tool for generating, converting, and manipulating PDF documents programmatically. It allows developers to create PDFs from various sources, such as HTML, URLs, and other PDFs, and perform operations like merging, watermarking, and compressing. With a PDF API, you can automate tasks, improve efficiency, and enhance the overall user experience.

At DevProToolkit API platform, we provide a robust and scalable PDF API that can be easily integrated into your application. Our API is designed to handle a wide range of use cases, from generating invoices and reports to creating contracts and certificates. With our API, you can focus on developing your core product while we take care of the PDF generation and manipulation.

What Is a PDF API?

A PDF API is an application programming interface that allows developers to interact with a PDF generation and manipulation system. It provides a set of endpoints and parameters that can be used to create, convert, and manipulate PDF documents programmatically.

Why Use a PDF API Instead of Libraries?

While libraries can be used to generate and manipulate PDFs, a PDF API offers several advantages. It provides a scalable and reliable solution, handles complex tasks, and requires minimal maintenance and updates. Additionally, a PDF API can be easily integrated into your application, allowing you to focus on developing your core product.

Getting Started

To get started with our PDF API, follow these simple steps:

1. Sign up for an account on our website.
2. Make a request to our API using the X-API-Key header.
3. Get the generated PDF document in response to your request.

API Reference

Our PDF API provides the following endpoints:

• GET/POST /api/pdf/generate: Generate a PDF document from HTML content or a URL.
• GET/POST /api/pdf/convert: Convert a PDF document to another format.
• GET/POST /api/pdf/merge: Merge multiple PDF documents into a single document.

The following parameters are supported:

Parameter	Description
html_content	The HTML content to generate the PDF from.
url	The URL to generate the PDF from.
page_size	The page size of the generated PDF.
orientation	The orientation of the generated PDF.
margin	The margin of the generated PDF.
watermark_text	The watermark text to add to the generated PDF.

cURL Examples

curl -X POST \
  https://api.commandsector.in/api/pdf/generate \
  -H 'X-API-Key: YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{"html_content": "..."}'

curl -X POST \
  https://api.commandsector.in/api/pdf/generate \
  -H 'X-API-Key: YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{"url": "https://example.com"}'

Python Integration

import requests

api_key = 'YOUR_API_KEY'
url = 'https://api.commandsector.in/api/pdf/generate'

data = {'html_content': '...'}
headers = {'X-API-Key': api_key, 'Content-Type': 'application/json'}

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

if response.status_code == 200:
    print('PDF generated successfully')
else:
    print('Error generating PDF')

JavaScript / Node.js Integration

const fetch = require('node-fetch');

const apiKey = 'YOUR_API_KEY';
const url = 'https://api.commandsector.in/api/pdf/generate';

const data = { html_content: '...' };
const headers = { 'X-API-Key': apiKey, 'Content-Type': 'application/json' };

fetch(url, { method: 'POST', body: JSON.stringify(data), headers })
  .then(response => response.json())
  .then(data => console.log('PDF generated successfully'))
  .catch(error => console.error('Error generating PDF', error));

Use Cases

Our PDF API can be used in a variety of scenarios, including:

• Generating invoices and receipts
• Creating reports and contracts
• Producing certificates and diplomas
• Converting web pages to PDFs

Advanced PDF Features

The DevProToolkit API platform offers a range of advanced features to enhance your PDF generation, including watermarks, headers and footers, page numbers, custom fonts, and password protection. These features allow for a high degree of customization and control over the output.

For example, to add a watermark to your PDF, you can use the following curl command:

curl -X POST \
  https://api.commandsector.in/pdf \
  -H 'Content-Type: application/json' \
  -d '{"html": "
Hello World
", "watermark": {"text": "Confidential", "opacity": 0.5}}'

This will generate a PDF with the specified HTML content and a watermark with the text "Confidential" at 50% opacity.

Comparison: PDF API vs Client-Side Libraries

When choosing a solution for generating PDFs, it's essential to consider the trade-offs between different approaches. The following table compares the DevProToolkit PDF API with popular client-side libraries:

Solution	Language	Setup Complexity	Serverless Compatible	Custom Styles	Output Quality
DevProToolkit PDF API	Any	Low	Yes	High	High
wkhtmltopdf	C++/Qt	Medium	No	Medium	Medium
Puppeteer	JavaScript	High	Yes	High	High
WeasyPrint	Python	Medium	No	Medium	High

This comparison highlights the advantages of using the DevProToolkit PDF API, including low setup complexity, serverless compatibility, and high customizability.

Integration Examples

The DevProToolkit PDF API can be easily integrated with a variety of frameworks and libraries. Here are some examples:

Django: Use the `requests` library to send a POST request to the API endpoint, passing in your HTML content and any desired options.

import requests
response = requests.post('https://api.commandsector.in/pdf', json={'html': '
Hello World
'})

Express.js: Use the `axios` library to send a POST request to the API endpoint, passing in your HTML content and any desired options.

const axios = require('axios');
axios.post('https://api.commandsector.in/pdf', { html: '
Hello World
' })

React: Use the `fetch` API to send a POST request to the API endpoint, passing in your HTML content and any desired options.

fetch('https://api.commandsector.in/pdf', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ html: '
Hello World
' }) })

Best Practices

To ensure optimal PDF generation, follow these best practices:

1. Optimize your HTML: Keep your HTML content simple and well-structured to improve rendering performance.

2. Use font loading strategies: Implement techniques like font caching or asynchronous font loading to reduce the impact of font rendering on performance.

3. Handle images efficiently: Use image compression and caching to minimize the size and loading time of images in your PDFs.

4. Leverage CSS styles: Utilize CSS to control the layout and appearance of your PDF content, rather than relying on inline styles or HTML attributes.

5. Test and iterate: Verify the quality and accuracy of your generated PDFs, and make adjustments as needed to ensure the best possible output.

6. Monitor performance: Keep an eye on the performance of your PDF generation workflow, and optimize it as needed to ensure fast and reliable output.
