# PDF to JSON Converter

> Export a PDF as JSON — both the recovered document structure and the raw line geometry.

PDF to JSON Converter runs entirely in your browser. The PDF is parsed on your own device with pdf.js, its paragraphs, headings and tables are recovered from the text layer and written into a genuine JSON file. Nothing is uploaded, which is the reason to use this on a contract, a payslip or a medical letter.

## FAQ

### Is my PDF uploaded to a server?

No. The document is parsed and converted by JavaScript running in this tab. It never touches the network, which you can confirm in your browser's network panel.

### Why is the output empty?

The PDF is a scan — an image of a page with no text underneath. Nothing can be extracted from it without OCR, which is a separate process. The tool says so rather than handing back an empty file.
