π What is OCR?
Optical Character Recognition (OCR) is a technology that converts different types of documents β such as scanned paper documents, PDFs, or images captured by a digital camera β into editable and searchable text.
This tool uses Tesseract.js, a JavaScript port of Google's Tesseract OCR engine, which runs entirely in your browser using WebAssembly. This means:
- β Your files never leave your device β complete privacy
- β No file size limits (performance may vary)
- β Works offline after the first load
- β No registration, no API keys, no hidden costs
πΌοΈ Supported File Types
- PDF documents β Scanned or image-based PDFs
- JPEG / JPG β Most common image format
- PNG β Lossless format with transparency support
- BMP β Bitmap images
- TIFF β High-quality images, often used in scanning
- GIF β Animated or static images
For best results, ensure your document has good contrast and clear text. Handwritten text may have lower accuracy.
π How OCR Works Under the Hood
- File Loading β Your file is read locally using the FileReader API.
- PDF Rendering β For PDFs, PDF.js renders each page to a canvas element without any external dependencies.
- Image Processing β The canvas image data is passed to Tesseract.js for analysis.
- Text Recognition β Tesseract.js identifies character shapes and converts them to machine-encoded text.
- Result Display β Extracted text is displayed, with page separators for multi-page PDFs.
π‘ Pro Tips for Better OCR Accuracy
- Use high-resolution scans (300 DPI or higher) for better results.
- Ensure the text is upright and not skewed.
- Select the correct language for the document β matching the language improves accuracy significantly.
- For small text, consider increasing the image resolution before scanning.
β Frequently Asked Questions
Yes, absolutely. All processing happens locally in your browser using Tesseract.js and PDF.js. No files are uploaded to any server β your documents remain on your device at all times. This makes the tool ideal for sensitive documents like contracts, invoices, or personal records.
The tool supports over 100 languages including English, Spanish, French, German, Italian, Portuguese, Chinese (Simplified & Traditional), Japanese, Korean, Arabic, Russian, Hindi, and many more. Select your language from the dropdown for optimal accuracy.
Tesseract.js is optimized for printed text recognition. While it can recognize some handwriting, accuracy may be lower. For best results, use scanned documents with clean, printed text.
