About PDF to JSON Converter

Our free PDF to JSON Converter is a powerful tool for extracting structured data from PDF documents and converting it into machine-readable JSON format. PDFs are designed for human reading, but extracting data programmatically can be challenging. This tool bridges that gap, making it easy to integrate PDF content into applications, databases, and data pipelines.

Why Extract PDF Data as JSON? Organizations store vast amounts of data in PDFs—invoices, reports, forms, research papers, and more. Converting these to JSON enables automated processing, data analysis, search indexing, and integration with modern web applications. Whether you're building a document management system, automating invoice processing, or analyzing research data, this converter provides the essential first step.

Key Features:
  • Extract text content from any PDF, including scanned documents with OCR.
  • Multiple extraction modes: simple text, structured (tables/forms), and layout preservation.
  • Flexible output formats: page array, merged text, or key-value pairs.
  • Optional document metadata extraction (title, author, creation date, etc.).
  • 100% client-side processing—your files never leave your device.

This tool is perfect for developers building document processing workflows, data scientists analyzing PDF reports, or anyone who needs to convert static PDFs into structured, machine-readable data. It works entirely in your browser using PDF.js, ensuring fast, secure conversion without server dependencies.

How to Use

Converting PDF to JSON is simple with these steps:

  1. Upload your PDF file by dragging and dropping or clicking to browse.
  2. Choose the extraction mode: text-only, structured, or layout-preserved.
  3. Select the output format that matches your use case.
  4. Optionally enable OCR for scanned documents and metadata extraction.
  5. Click "Convert to JSON" and wait for processing to complete.
  6. Copy the JSON or download it as a file.

Frequently Asked Questions

What's the difference between extraction modes?

  • Text Only: Simple text extraction without formatting. Fastest option for basic content.
  • Structured: Attempts to identify tables and forms for better data organization.
  • Preserve Layout: Includes position coordinates for each text element, useful for precise layout reconstruction.

Which output format should I choose?

  • Array of Pages: Best for multi-page documents where you need to maintain page structure.
  • Merged Text: Combines all text into a single string. Ideal for full-text search or word counting.
  • Key-Value Pairs: Organizes content by page. Good for document analysis and processing.

What is OCR and when should I use it?

OCR (Optical Character Recognition) converts images of text into actual text characters. Enable OCR when working with scanned PDFs or image-based documents where the text isn't selectable. Note that OCR requires additional processing and may result in larger file sizes.

Can this handle password-protected PDFs?

Currently, the tool cannot extract text from password-protected or encrypted PDFs. You'll need to remove the password protection using a PDF editor before conversion. For security and privacy reasons, we recommend only converting documents you have permission to access.

Is my data private and secure?

Yes, completely. All PDF processing happens locally in your browser using PDF.js. Your documents are never uploaded to any server, ensuring that sensitive information remains on your device. This makes it safe to convert confidential business documents, personal records, or any sensitive data.

Does this work with all PDF files?

The tool works with most standard PDF files, including those generated by word processors, scanners, and design tools. However, very complex layouts, heavily formatted documents, or PDFs with embedded fonts may require manual review of the extracted JSON. For best results, test with a sample document first.
