Frequently Asked Questions

Got questions? We've got answers.

Yes! Kaizen OCR works completely offline after installation. The only time internet is required is for initial license validation. All OCR processing, file conversion, and PDF operations happen entirely on your computer. Your documents are never uploaded to any server, ensuring complete privacy and security.
Tesseract is a traditional OCR engine that supports 100+ languages and works great for most documents. The AI-powered engine uses advanced machine learning models that excel at extracting tables, structured data, key-value pairs, and handling complex layouts. AI OCR is particularly effective for Asian languages, handwriting, and documents with mixed content. We recommend trying both to see which works best for your specific documents.
There's no limit on batch processing! You can add hundreds or even thousands of files at once. Simply drag and drop files or entire folders into the application. The software will process them one by one with a progress indicator showing the status. This is perfect for digitizing large document archives.
Kaizen OCR supports all major image formats including PNG, JPEG/JPG, TIFF, BMP, GIF, and WebP. For file conversion, we support 13 formats: PDF, Word (DOCX), Word (DOC), RTF, HTML, TXT, ODT, EPUB, PNG, JPEG, TIFF, BMP, and GIF.
Absolutely! Kaizen OCR handles both native (text-based) PDFs and scanned PDFs. For native PDFs, use "Direct Text Extraction" for fastest results. For scanned PDFs, choose either Tesseract or AI OCR engine. The software automatically converts each PDF page to an image and performs OCR to extract the text.
We offer 11 preprocessing steps to improve OCR accuracy: Remove Alpha Channel, Convert to Grayscale, Intelligent Upscaling, Advanced Denoising, Contrast Enhancement (CLAHE), Unsharp Masking, Morphological Gradient, Deskew, Adaptive Thresholding, Morphological Cleanup, and Add Border. You can enable any combination and reorder them as needed. These are especially useful for low-quality scans or photos of documents.
No subscriptions required! We offer two paid options: Pro Annual ($49/year) and Pro Lifetime ($99 one-time). The lifetime option is a single payment that gives you unlimited usage forever, including all future updates. No recurring charges, no hidden fees.
Kaizen OCR is currently available for Windows 10 and Windows 11. Both 64-bit versions are fully supported. We're considering Mac and Linux versions based on user demand — let us know if you're interested!
OCR accuracy depends on image quality, but with good quality documents, you can expect 95-99% accuracy. The AI engine typically performs better on complex layouts and Asian languages. For best results, use the preprocessing options to enhance image quality before OCR. The deskew, denoising, and contrast enhancement features can significantly improve accuracy on challenging documents.
Yes! We offer a 30-day money-back guarantee. If you're not satisfied with Kaizen OCR for any reason, contact our support team within 30 days of purchase for a full refund. We recommend trying the free version first to ensure it meets your needs before purchasing.
