About OCR to JSON (Text and Word Boxes)

Extracts text using the same OCR engine as our other tools, but returns structured JSON — the full text, an overall confidence score, and individual word-level data including each word’s position in the original image.

Every field in the output comes directly from what Tesseract actually returns — nothing is fabricated or estimated. If a field isn’t present in the underlying OCR result, it’s simply not included, rather than filled with a guessed value.

Useful specifically for feeding OCR results into another script, program, or automated workflow expecting structured data rather than plain text.

Frequently Asked Questions

How do I convert an image to JSON?

Upload a JPG, PNG or WebP, run the OCR, and download ocr-result.json. This tool reads text, so the JSON holds the full recognized text, an overall confidence score, and every word with its confidence and bounding box. It does not describe the picture.

How do I convert an image to a JSON file?

Click Download JSON after recognition to save ocr-result.json. Each word entry has text, confidence and bbox coordinates. You can also copy the JSON from the box. Nothing is invented: fields the OCR engine does not return are left out.

Does OCR to JSON extract fields like totals or dates?

No. It returns raw text and word positions, not labeled fields. For receipts use Receipt OCR, and for invoices use Invoice OCR. Both pull out fields such as total and date using pattern matching and let you edit them before exporting JSON.

Is the image uploaded when I convert it?

No. OCR runs inside your browser, so the image never leaves your device. The first use downloads about 15MB of OCR engine and English language data, which is then cached. Only English is supported for this tool.
