完全ガイド: PDFのOCR
OCR (Optical Character Recognition) transforms scanned documents and images into searchable, selectable text. When you scan a paper document, the result is essentially a picture of the text — it looks like text but your computer treats it as an image, making it impossible to search, copy, or edit. iLoveDoc's PDF OCR tool analyzes the visual patterns in your scanned pages and converts them into actual digital text that can be searched, copied, and indexed. The OCR engine recognizes characters in multiple languages and handles various fonts, sizes, and even slightly skewed or degraded text. The resulting PDF is a "sandwich" format where the original scanned image is preserved as the visible layer while invisible, searchable text is added behind it. This means your document looks exactly the same but you can now search for words, copy text passages, and use screen readers for accessibility. Processing happens entirely in your browser for privacy.
