PDF to Word and Microsoft Documents API & SDK

Convert your PDFs to Word files online in just a few clicks.

Transform PDFs into Editable Office
Documents with Precision

The PDF Convert Web API provides developers with a powerful toolkit for programmatically converting PDF files into editable Microsoft Office formats. This RESTful API extracts both text and images from PDF documents, maintaining the original formatting structure during conversion—regardless of document complexity or size.

Built for development teams that require reliable document processing capabilities, our conversion engine handles tables, images, fonts, and complex layouts with exceptional accuracy. The API delivers consistent results across diverse document types, from simple text documents to complex multi-column layouts with embedded graphics and tables.

Unlike generic conversion tools that sacrifice formatting fidelity for processing speed, our PDF to Word conversion technology preserves the visual integrity of your documents while providing the programmatic control needed for integration into custom workflows, enterprise applications, and automated document processing systems.

Key Technical Features

High-Fidelity Format Preservation

Our conversion engine maintains the original document structure during PDF to Word conversion, preserving fonts, spacing, tables, and images. The sophisticated text flow analysis ensures that paragraphs, columns, and page breaks appear in the converted document exactly as they appeared in the source PDF. This eliminates the need for manual reformatting after conversion, saving development teams significant time when implementing document workflows.

Multi-Format Output Support

Convert PDF files to multiple Microsoft Office formats with a single API. Beyond standard DOCX output, the API supports conversion to Excel (XLSX) with customizable table handling and PowerPoint (PPTX) with preserved visual elements. Additional format support includes RTF and TXT, providing flexibility for different application requirements and ensuring compatibility with various operating systems, including macOS.

OCR Technology Integration

When working with scanned documents, our API can process image-based PDFs through integrated OCR technology. The system identifies text within images, making it searchable and editable in the resulting Office document. This capability transforms previously static, scanned documents into fully functional digital assets that can be edited, searched, and processed programmatically.

Granular Conversion Control

The API provides precise control over the conversion process through multiple parameters:

Selective page processing (convert specific pages or page ranges)

Password-protected document support

Table extraction options for data-focused conversions

Excel-specific conversion options:

  • tablePerSheet: places each table on a separate sheet
  • pagePerSheet: places all content from each page on a separate sheet
  • documentPerSheet: places entire document on a single sheet

Asynchronous Processing Architecture

Built for performance and scalability, the API uses an asynchronous processing model that prevents blocking operations and enables efficient handling of large documents. After submitting a conversion request, you receive an operation ID that can be used to check conversion status and retrieve results, making it ideal for integration into systems with high-volume document processing requirements.

POST/pdf-convert/v1
Content-Type:multipart/form-data

[email protected]
convertType=word

Response:
{
"id":"3fa85f64-5717-4562-b3fc-2c963f66afa6"
}

Simple Implementation Process

Integrating PDF conversion capabilities requires minimal development effort. The straightforward two-step process involves:

Upload a PDF file

Submit your PDF document through a standard multipart/form-data POST request, with optional parameters for customization.

Retrieve the converted document

Use the operation ID to check conversion status and download the resulting Office file when processing is complete.

This simplified approach allows development teams to add powerful document conversion features to their applications with minimal code.

Comprehensive Security Controls

Our API implements robust security measures to protect sensitive document data during the conversion process. All API communications are encrypted using TLS, and document data is processed securely with strict isolation between tenant workloads. The system supports password-protected PDFs and maintains document confidentiality throughout the conversion pipeline.

FAQ

How accurately does the API preserve document formatting?

The conversion engine maintains high-fidelity formatting across document elements, including complex tables, embedded images, and multi-column layouts. The resulting Word document maintains the visual integrity of the original PDF while providing full editability.

What programming languages can I use with the API?

The RESTful API can be integrated using any programming language capable of making HTTP requests, including Python, JavaScript/Node.js, Java, C#, PHP, and Ruby. Code examples are provided for common languages to accelerate implementation.

Is the conversion process secure?

Yes. All document data is encrypted during transmission and processing. The API implements strict isolation between tenant workloads, and documents are processed in secure, ephemeral environments. For higher security requirements, an on-premises SDK option is available.

What happens if a conversion fails?

The API provides detailed error information through standard HTTP status codes and descriptive error messages. The asynchronous processing model allows you to check conversion status and handle exceptions gracefully within your application logic.

Can I convert password-protected PDFs?

Yes. The API accepts an optional password parameter for processing protected documents, maintaining security throughout the conversion process while delivering editable output.

What are the technical requirements for implementation?

For API integration, you only need the ability to make HTTPS requests and process JSON responses. There are no specific server requirements beyond standard web communication capabilities. For the SDK option, specific system requirements are provided in the technical documentation.
