Why Use This OCR Tool?
Traditional OCR services require uploading your images to cloud servers, raising privacy concerns. Our OCR tool runs entirely in your browser using Tesseract.js, a JavaScript port of the powerful Tesseract OCR engine compiled to WebAssembly.
Common Use Cases:
- Extract text from screenshots for editing
- Digitize printed documents and receipts
- Convert scanned PDFs to editable text
- Extract text from photos of whiteboards or notes
- Accessibility: Make image text searchable and screen-reader friendly
Tips for Best Results:
- Use high-resolution images with clear, legible text
- Ensure good contrast between text and background
- Avoid skewed or rotated text when possible
- Use images with standard fonts (handwriting may have lower accuracy)
Frequently Asked Questions
How accurate is the OCR?
Tesseract.js provides excellent accuracy for printed text, typically 95%+ for clear images. Accuracy depends on image quality, font clarity, and language. For best results, use high-resolution images with good contrast and avoid handwritten text.
Is my image data secure?
Yes, absolutely. All OCR processing happens entirely in your browser using JavaScript and WebAssembly. Your images and extracted text never leave your device or get sent to any server.
What image formats are supported?
The OCR tool supports JPG, PNG, WebP, GIF, BMP, and other common image formats. The maximum file size is 10MB to ensure smooth processing on all devices.
Does this work offline?
Yes! Once the page loads and the Tesseract.js model is cached (~2-4 MB), you can use this tool completely offline. Our PWA ensures the tool remains available even without internet.
Can it recognize handwritten text?
Tesseract is optimized for printed text and may have lower accuracy with handwritten text. For best results with handwriting, ensure very clear, legible writing with good contrast.
Will this work on my mobile phone?
Yes! The tool is optimized to run on mobile browsers. Processing may take slightly longer on lower-end devices, but it works reliably on both iOS and Android.
What languages are supported?
Currently, the tool is configured for English text. Tesseract supports 100+ languages, and we may add multi-language support in the future based on user demand.
Why is the first extraction slow?
The first time you use the tool, it needs to download the Tesseract.js OCR engine (~2-4 MB). After this initial download, the engine is cached and subsequent extractions are much faster.
