The Best Tool to Digitize Scanned Documents

In the modern paperless office, dealing with scanned documents (like invoices, contracts, or old book pages) is a common challenge. Unlike "native" PDFs where you can select text, scanned PDFs are essentially images wrapped in a PDF file. You cannot search, edit, or copy text from them. TranslateInHindi.com's Scanned Document Reader solves this by using cutting-edge Optical Character Recognition (OCR) technology.

How OCR Technology Works

Our tool uses the Tesseract OCR engine, an open-source library originally developed by HP and now maintained by Google. It breaks down the document processing into several steps:

1. Pre-processing: The image is converted to grayscale, and noise (like coffee stains or scan lines) is reduced. The image is also "deskewed" to correct any tilt.
2. Segmentation: The AI identifies blocks of text, paragraphs, and lines.
3. Character Recognition: It matches the pixel patterns of each character against a database of fonts.
4. Post-processing: The system uses a language model (English) to correct spelling errors and ensure the output makes grammatical sense.

Common Challenges with Scanned Docs

While our tool is powerful, the quality of the output depends heavily on the quality of the input scan. Here are common issues:

• Low Resolution: Scans below 300 DPI (Dots Per Inch) may result in errors.
• Handwriting: While printed text is recognized easily, handwriting is much harder for AI to decipher. (Use our Handwriting OCR tool for that!)
• Complex Layouts: Multiple columns, tables, or text wrapped around images can sometimes confuse the line-reading order.

Security and Privacy

We understand that scanned documents often contain sensitive information. Our tool processes files entirely within your web browser (client-side) using WebAssembly. This means your confidential contracts and financial statements never leave your computer. We do not store or view your files.
