PDF to JSON Converter – Extract PDF Data to JSON Online

Extract text from digital PDFs and convert to JSON directly in your browser. No server upload, no external processing — your file never leaves your device.

Limitation: This tool supports digital (text-based) PDFs only. Scanned image PDFs require OCR and are not yet supported.

Page-by-Page: Each page extracted as a separate JSON object.
Text-Based PDFs: Works with PDFs created by word processors or exported from software.
Privacy-First: Parsing runs entirely in the browser via pdf.js.
Download JSON: Save the extracted structure as a .json file.

How to Extract PDF Data to JSON

Click Upload PDF or drag and drop a .pdf file. The tool reads each page and outputs a JSON array where each element is a page object with a page number and content string. Click Download JSON to save the result.

Digital vs Scanned PDFs

Digital PDFs ✓

Created by word processors, exported from software. Text layer is embedded. This tool works.

Scanned PDFs ✗

Pages stored as images. Text must be read by OCR. Not supported in this version.

Processing Extracted JSON

After extracting, view the result as a JSON table to scan content across pages, or use the JSON validator to confirm the structure. For structured spreadsheet data you can import from Excel directly — see our Excel to JSON converter.

Frequently Asked Questions

Is my data safe with this JSON tool?

Yes. This tool uses 100% client-side processing. Your JSON data never leaves your browser and is never sent to our servers, ensuring maximum privacy and security.

Does this tool work offline?

Once the page has loaded, all processing happens locally in your browser. You can disconnect from the internet and the tool will continue to work — no server connection is required to format, validate, or convert your JSON.

Is there a file size limit?

No server-side limits apply because everything runs in your browser. Practical limits depend on your device's memory, but modern browsers handle JSON files of tens of megabytes without issue.

What types of PDFs are supported?

This tool extracts text from digital (text-based) PDFs — files that contain selectable text. Scanned PDFs that are images of pages require OCR and are not currently supported. If your PDF was produced by a word processor or exported from software, it is likely text-based.

How is the extracted text structured?

Text is extracted page by page. Each page becomes an object in the output array with a 'page' number and a 'content' string. For documents with clearly labelled sections, the structure will reflect the visual layout as much as the PDF's text layer allows.

Why doesn't my scanned PDF work?

Scanned PDFs store pages as images, not text. Extracting data from them requires Optical Character Recognition (OCR), which is computationally intensive and not yet available in this tool. Use a desktop OCR tool to convert scanned pages to text first.

Is the file uploaded to your servers?

No. PDF parsing is done entirely in your browser using pdf.js. Your file is never sent to any server — it stays on your device throughout the process.
