What is OCR and Why Extract Text from Images?

OCR (Optical Character Recognition) is technology that converts images containing text into editable, searchable text. OCR helps you digitize text from many sources: photos of documents, invoices, receipts — no manual retyping needed. Scan books, newspapers, magazines — create searchable digital versions. Screenshots containing text — quickly extract content. Whiteboard photos, notes — store as text. This tool is especially useful when you need to extract content from images for editing, translation, or storage.

Frequently Asked Questions

What is OCR?

OCR (Optical Character Recognition) is technology that converts images containing text (photos, scans, screenshots) into editable, copyable, and searchable text.

How accurate is the OCR?

Accuracy depends heavily on image quality. With clear, high-contrast images and standard printed fonts, accuracy can reach 95-99%. Handwriting, decorative fonts, blurry images, or complex backgrounds will have lower accuracy.

Is my image uploaded to a server?

NO. The tool uses Tesseract.js running entirely in your browser via WebAssembly. Images are never sent anywhere — 100% local processing on your machine. Completely safe for sensitive documents.

Why is the first OCR slower?

The first time you use it, Tesseract.js needs to download language data (trained models) for your selected language, about 10-15MB per language. This data is cached in the browser, so subsequent uses will be much faster.

What image types give the best results?

Printed text on a plain background works best. Ensure good contrast, horizontal orientation, and at least 300 DPI resolution. Avoid handwriting, decorative fonts, or images with complex backgrounds for best accuracy.
