What the JSON Output Looks Like

In Full Document mode, the extracted JSON follows a clean, predictable schema with document metadata and per-page content blocks.

"document": { "metadata": { "title": "Annual Report 2025", "author": "Jane Smith", "totalPages": 12, "pdfVersion": "1.7" }, "pages": [ { "page": 1, "paragraphs": [ { "index": 0, "text": "Executive Summary", "lines": ["Executive Summary"] } ], "lineCount": 42, "wordCount": 318 } ] }

PDF to JSON — Common Questions

Everything you need to know about converting PDF data to structured JSON format online.

Is this PDF to JSON converter really free?
Yes, completely free with no signup, no subscription, and no usage limits. Convert as many PDFs as you need, as many times as you like, with no restrictions or hidden fees.
Is my PDF file uploaded to a server?
No. The entire extraction process runs locally in your browser using PDF.js. Your file never leaves your device — there is no server processing, no cloud upload, and no data retention of any kind.
Which extraction mode should I choose?
Use Full Document for rich structured output with metadata and page hierarchy. Use Line by Line for logs or reports. Use Word by Word for NLP or text analysis pipelines. Use Metadata Only for cataloguing or indexing document collections.
Will scanned PDFs work with this tool?
Scanned PDFs contain images rather than text, so no text can be extracted directly. This tool works best with text-based PDFs. For scanned documents, OCR software is required before converting to JSON.
What is the difference between pretty print and minified JSON?
Pretty print formats the JSON with indentation and line breaks for easy human reading. Minified JSON removes all whitespace to produce the smallest possible file size — ideal for API payloads and data pipelines.
Can I extract only specific pages to JSON?
Yes. Use the Start Page and End Page fields to extract any page range from your PDF. Set End Page to 0 to include all pages from the start page to the end of the document.
