Export the mapped coordinate data as a structured JSON file instantly.

A specialized data extraction tool built for developers, data scientists, and ML engineers. Instead of a flat text dump, this utility parses the PDF binary stream and exports every text segment as a structured JSON object. It includes the exact physical location (X,Y coordinates), width, height, and font dictionary properties. This is the ideal tool for training layout-aware OCR models or building precise automated data scrapers without uploading sensitive datasets to a cloud server.

Key Features

Precise Coordinate Mapping

Exports the exact bounding box (X, Y, width, height) of every text node.

Font Detection

Includes the internal PDF font-name ID for typography extraction.

Browser-Based Privacy

The entire binary text stream is parsed locally in your RAM; no data is sent to our servers.

Frequently Asked Questions
