Frequently Asked Questions about OCR PDF
What is OCR and how does it work?
OCR (Optical Character Recognition) is technology that converts images of text into machine-readable text. Our tool uses Tesseract.js, an open-source OCR engine, to analyze each page of your PDF or image, identify characters, and extract them as searchable text. The entire process runs locally in your browser.
What file types are supported?
We support PDF files (both text-based and scanned) as well as common image formats including JPG, PNG, and WebP. For PDFs, each page is rendered and processed individually for text extraction.
How accurate is the OCR?
OCR accuracy depends on image quality, text clarity, and font type. Clean, high-resolution scans with clear text produce the best results. Tesseract.js is a powerful OCR engine that handles most printed text well. For handwritten text or poor quality scans, accuracy may be lower.
Is my document secure during OCR?
Absolutely! The entire OCR process happens locally in your browser using Tesseract.js. Your PDF and images never leave your computer — no uploads to any server. This ensures complete privacy for your sensitive documents.
What languages are supported?
We support multiple languages including English, French, Spanish, German, Italian, Portuguese, Russian, Chinese (Simplified), and Japanese. Select the appropriate language for best results. Multi-language documents may require separate processing.
How long does OCR take?
Processing time depends on the number of pages, image quality, and your device performance. A single page typically takes 5-15 seconds. Larger documents may take longer. You'll see progress updates as each page is processed.
Can I download the extracted text?
Yes! After OCR is complete, you can copy the text to clipboard or download it as a TXT file. This makes it easy to use the extracted content in other applications.
