About Extrator de Texto OCR

OptiPix OCR Text Extractor uses Tesseract.js, the leading open-source OCR engine compiled to WebAssembly, to recognize and extract text from images directly in your browser. It supports over 100 languages including English, Spanish, French, German, Chinese, Japanese, Korean, Arabic, and many more. Simply drop an image containing text — a document scan, a screenshot, a photo of a sign, a receipt — and the tool will extract all readable text in seconds. The extracted text is fully editable, so you can correct any recognition errors before copying or downloading. Unlike cloud OCR services, your documents never leave your device, making this ideal for sensitive documents like medical records, legal papers, or financial statements. The Tesseract engine downloads language data on first use (about 15 MB per language) and caches it for offline use. Recognition accuracy is excellent for clean printed text and reasonable for handwritten or stylized fonts.

How It Works

The tool uses Tesseract.js, a WebAssembly port of the Tesseract OCR engine. It preprocesses the image, applies text detection algorithms to locate text regions, then uses trained neural network models for each language to recognize individual characters and words with high accuracy.

Use Cases

•Digitize printed documents and receipts
•Extract text from screenshots for editing
•Convert photos of whiteboards or notes to text
•Extract text from signs and labels in foreign languages
•Archive handwritten notes as searchable text

Frequently Asked Questions

What languages are supported?

Over 100 languages are supported including English, Spanish, French, German, Portuguese, Italian, Chinese (Simplified and Traditional), Japanese, Korean, Arabic, Hindi, and many more.

How accurate is the text recognition?

Accuracy is excellent for clean printed text in good lighting (95%+ for most documents). Handwritten text, unusual fonts, and low-quality images may produce lower accuracy.

Can I extract text from PDFs?

The tool accepts image files. For PDFs, you would first need to convert PDF pages to images (using a screenshot or PDF-to-image tool) and then run OCR on those images.

How large is the language data download?

Each language pack is approximately 10-15 MB. It downloads once on first use for your selected language and is cached for offline use.

Can I edit the extracted text?

Yes. The extracted text appears in an editable text area where you can correct any errors, then copy to clipboard or download as a text file.
