🧠 What Is OCR?

OCR (Optical Character Recognition) is the process of recognizing and extracting text from images, scanned documents, or photos.
It enables you to convert printed or handwritten text into machine-readable content.

Common use cases:

• Scanning receipts, invoices, or contracts
• Digitizing books, forms, and printed documents
• Copying text from screenshots
• Translating printed material into other languages
• Archiving old handwritten notes

OCR bridges the gap between the physical and digital worlds, turning static images into usable text data.

⚙️ How OCR Works

OCR relies on several key steps:

1. Image Preprocessing
   The tool enhances image contrast, removes noise, and aligns text.

2. Text Detection
   It identifies blocks, lines, and words using deep learning models.

3. Character Recognition
   Each character is analyzed against trained models using neural networks.

4. Post-Processing
   The recognized text is corrected using language models and dictionaries.

Modern OCR systems use AI and machine learning to continuously improve accuracy — even for tricky fonts or curved text.

🔒 Why Client-Side OCR Is Safer

Most online OCR tools send your files to remote servers, which means your data may be stored or analyzed elsewhere.
Our OCR Tool performs client-side recognition, meaning:

• Your image never leaves your device

⚡ Tips for Best OCR Accuracy

To get clean, precise results:

1. Use clear, high-resolution images.
2. Avoid glare or shadows over text.
3. Align the text horizontally when taking photos.
4. Use black text on a light background if possible.
5. For handwriting, write clearly with consistent spacing.

Bonus Tip: If your image is large, first optimize it using our Image Compressor Tool before OCR — it loads faster and processes better.
