OCR (Optical Character Recognition) functions by analyzing text images and converting them to editable format through pattern and shape recognition. Several factors can impact OCR performance: Image clarity and resolution - unclear or low-quality images yield poor results. Typography - decorative or unusual fonts may not be accurately identified. Document state - tilted, rotated, or damaged files can decrease accuracy. Visual interference - complex backgrounds or watermarks can disrupt text recognition. Handwritten content presents particular challenges for OCR systems. For optimal results, use high-resolution, well-illuminated scans with standard, clear typefaces.

Languages reading right-to-left (Arabic, Hebrew) and Asian character systems (Chinese, Japanese, Korean) may need specialized handling and could take longer to process. Font compatibility issues might impact how converted documents appear in certain languages. For optimal results with non-Latin scripts, use documents with standard, legible fonts.
