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.
This tool runs 100% in your browser. All computation happens locally on your device — your input is never uploaded to any server. Results are for reference only.
This tool reads information out of images in two stages. First, optical character recognition (OCR) — powered by Tesseract.js running in a Web Worker — scans the pixels of your screenshot, receipt, or document and converts them into plain text. That raw OCR text is often messy: words are misread and layout is flattened. In the second stage a local language model receives that text and re-structures it according to the format you picked — JSON key-value pairs, a CSV table, simple Key: Value lines, or a Markdown table — following strict rules to only keep facts that are actually present and to clean up OCR artifacts. For JSON output the tool also parses the reply into a clean field list. Because both OCR and the model run in your browser, confidential documents never leave your device.
A screenshot is OCR'd into raw text with Tesseract.js, then a local LLM re-structures that text into JSON, CSV, key-value, or Markdown output.
Yuki screenshots a paper receipt from her local coffee shop and clicks Extract Data with JSON selected. She never uploads the image — both stages run locally.
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.
Extract text and structured data from screenshots, receipts, and document images. OCR + AI structuring. 100% in-browser, no upload, free.
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.
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.
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.
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.
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.
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.
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.
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.
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.
