Extract text and structured data from screenshots — OCR + AI, 100% in your browser
Upload an image (screenshot, document scan, receipt) and click "Extract Data" to get structured text.
To extract data: upload an image — the tool uses Tesseract.js OCR to read text, then AI structures it into JSON, CSV, or key-value pairs, all in your browser.
FreeToolHub AI Data Extractor is a free browser-based tool that extracts structured data from images using OCR and AI, no signup, no upload.
About this tool
Extract text and structured data from screenshots, receipts, and document images. OCR + AI structuring. 100% in-browser, no upload, free.
What Is the AI Data Extractor?
The AI Data Extractor combines browser-based OCR (Optical Character Recognition) with AI-powered text structuring to extract data from images. Upload a screenshot, receipt, invoice, form, or any document image, and the tool first extracts all text using OCR, then uses a local AI model (SmolLM2) to structure the text into your chosen format — JSON, CSV, key-value pairs, or markdown table. Everything runs in your browser with no data upload.
Who Should Use This Tool?
This tool is for anyone who needs to digitize information from images: professionals digitizing receipts for expense reports, students extracting data from textbook screenshots, developers parsing data from UI screenshots, and anyone who needs to convert image-based information into structured, machine-readable data. The tool is especially useful for batch-processing receipts and invoices where manual data entry is tedious.
How Does This Tool Work?
The process has two stages: (1) OCR — the tool uses Tesseract.js, a browser-based OCR engine, to extract all text from the uploaded image. This works entirely offline after the initial OCR language data is loaded. (2) AI Structuring — the extracted text is sent to the SmolLM2 AI model running locally in your browser, which analyzes the text and structures it into your chosen format (JSON, CSV, key-value, or markdown). The AI cleans up OCR artifacts, identifies field names and values, and organizes the data into a useful structure.
Frequently asked
Is my image sent to a server?
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.
What image formats are supported?
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.
What output formats are available?
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.
How accurate is the OCR?
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.
Can I extract data from tables?
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.
Is this data extractor free?
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.
