Question 1

Is my image sent to a server?

Accepted Answer

No. Both the OCR engine and the AI model run 100% in your browser. Your image is processed locally and never uploaded. There is no signup, no account, and no data collection.

Question 2

What image formats are supported?

Accepted Answer

The tool supports PNG, JPG, JPEG, and WebP formats. For best OCR results, use high-resolution images with clear text. Blurry or low-contrast images may produce inaccurate results.

Question 3

What output formats are available?

Accepted Answer

Four formats: JSON (structured key-value pairs), CSV (comma-separated table), Key-Value (simple "Key: Value" lines), and Markdown (formatted table). You can switch formats before or after extraction.

Question 4

How accurate is the OCR?

Accepted Answer

OCR accuracy depends on image quality, text clarity, and font. Tesseract.js works well with printed text, screenshots, and scanned documents. Handwritten text or very stylized fonts may not be recognized accurately. The AI structuring step helps clean up common OCR errors.

Question 5

Can I extract data from tables?

Accepted Answer

Yes. The AI model attempts to preserve tabular structure when extracting data. For CSV and markdown output, the data is formatted as a table. For JSON output, table rows are converted to structured objects.

Question 6

Is this data extractor free?

Accepted Answer

Yes, 100% free with no signup, no API key, no usage limits, and no watermark. The OCR engine and AI model both run in your browser, so there are no server costs.
