Why convert PDF to JSON?

JSON is the language of pipelines. Once a PDF becomes JSON, it stops being a locked document and becomes data you can query, filter, validate, store in a database, or pass to the next step of a workflow — no PDF library required downstream.

Unlike plain text, this output keeps the geometry of the document: every line comes with x/y coordinates, font size, and font name. That is what you need for layout analysis — finding the value next to a label on an invoice, detecting headers from font sizes, splitting columns, or building training datasets for document AI models.

Example output

{
  "metadata": {
    "title": "Q2 Financial Report",
    "author": "Finance Team",
    "creationDate": "2026-04-02T09:14:00Z"
  },
  "pageCount": 12,
  "pages": [
    {
      "pageNumber": 1,
      "width": 595.28,
      "height": 841.89,
      "text": "Q2 Financial Report...",
      "lines": [
        {
          "text": "Q2 Financial Report",
          "x": 56.7, "y": 780.2,
          "fontSize": 24, "fontName": "Helvetica-Bold"
        }
      ]
    }
  ]
}

How it works

1

Upload your PDF

Drag and drop or click to select a PDF file from your device. It is read locally — never uploaded.

2

JSON is generated

The engine reads every page and structures metadata, text, and line coordinates into clean, machine-readable JSON.

3

Copy or download

Copy the JSON to your clipboard or download it as a .json file, ready for your scripts and pipelines.

What extracts well — and what has limits

Extracts well

  • Digital PDFs of any size — invoices, reports, forms
  • Document metadata (title, author, dates)
  • Per-line positions, font names, and font sizes
  • Page dimensions for coordinate mapping

Known limits

  • Scanned PDFs — no text layer, OCR needed (available in the ParseDocu API)
  • Tables come as positioned lines, not rows — see table extraction
  • No semantic labels — the API can extract fields like totals or dates
  • Images and vector graphics are not exported

Frequently asked questions

What does the JSON output include?

The output includes document metadata (title, author, creation and modification dates), and for each page: its dimensions, the full text content, and every text line with its position coordinates and font information.

Is my PDF uploaded to a server?

No. The entire extraction happens in your browser using JavaScript (PDF.js). Your file never leaves your device — safe for invoices, contracts, and any confidential document.

What are the text coordinates useful for?

Coordinates let you reason about layout programmatically: detect columns, find a value positioned to the right of a label (like a total on an invoice), rebuild reading order, or crop a region of interest. They are the raw material of document layout analysis.

Is the JSON schema stable across files?

Yes. Every conversion produces the same shape — metadata plus an array of pages, each with dimensions, text, and lines — so you can write parsing code once and run it on any PDF.

Does it work with scanned PDFs?

No — scanned PDFs are images without a text layer. They need OCR, which is available through the ParseDocu API for both scans and photos of documents.

Does it extract tables as structured rows?

Not directly: you get every cell as a positioned text line, which lets you rebuild simple tables from the coordinates. For ready-to-use rows and columns, the ParseDocu API has a dedicated table extraction endpoint.

Is this tool really free?

Yes — free, unlimited, no account required. It is our way of showing what ParseDocu does before you try the API.

Can I convert PDFs to JSON programmatically?

For automated pipelines, use the ParseDocu API: one POST request returns structured output at scale, with OCR and table extraction included, and connectors for Zapier, Make, and n8n. The free tier includes 1,000 credits.

Need OCR, field extraction, or automation?

The ParseDocu API turns digital and scanned PDFs into structured data at scale — via REST, Zapier, Make, or n8n. Start with 1,000 free credits.
