Optical Character Recognition (OCR) transforms images of text into editable, searchable text. Whether you need to extract text from a scanned document, screenshot, or photo of a sign, modern OCR tools make it possible with high accuracy.
What Makes OCR Work?
Traditional OCR analyzed character shapes pixel by pixel. Modern OCR engines like Tesseract.js use neural networks trained on millions of text samples across multiple languages. This allows them to:
Recognize text even when slightly rotated or skewedHandle mixed fonts and sizes in the same imageDetect text in 100+ languagesProcess both printed and handwritten text (with varying accuracy)When to Use OCR
Common use cases include:
Scanning documents**: Convert paper documents to searchable PDFs or text filesExtracting code from screenshots**: Copy code from error messages or configuration screensReading signs and menus**: Translate or copy text from photos taken while travelingData entry automation**: Extract information from invoices, receipts, and formsAccessibility**: Convert image-based text to screen-reader-compatible formatsHow Our OCR Tool Works
Our OCR tool runs Tesseract.js entirely in your browser:
Upload any image (PNG, JPEG, WebP, BMP, TIFF)Select the text languageClick "Extract Text"The Tesseract.js worker processes the image locallyCopy the extracted text or download it as a TXT fileSupported languages: English, Spanish, Japanese, French, German, Italian, Portuguese, Chinese (Simplified), Russian, Arabic, Korean.
Tips for Better OCR Results
**Higher resolution**: 300 DPI or above gives much better accuracy than 72 DPI**Good contrast**: Dark text on light background works best**Straight text**: Rotate images so text is horizontal**Clean images**: Remove noise, shadows, and artifacts when possible**Correct language**: Always select the actual language for best character recognition**Crop to text area**: Remove borders and irrelevant parts of the imagePrivacy First
Unlike cloud-based OCR services that send your images to remote servers, our tool processes everything on your device. Sensitive documents like medical records, contracts, and personal letters stay private. After loading the page, you can go offline and OCR still works.
