## 🧠 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**](/ocr-tool) performs **client-side recognition**, meaning:
– Your image never leaves your device
– No data is transmitted to servers
– No privacy risk, no third parties
It’s ideal for confidential or sensitive content such as contracts, IDs, or personal documents.

## ⚡ 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**](/image-compressor) before OCR — it loads faster and processes better.
