CatOCR

CatOCR is a free online optical character recognition service designed to convert text from images and scanned PDFs into editable digital text. The core functionality revolves around extracting written content from various image formats—including photographs, screenshots, scanned documents, and PDF files—without requiring any software installation or account registration. Users can upload images by dragging and dropping them into the designated area, clicking the local file selection button, or pasting directly from the clipboard using Ctrl+V. The system then processes the image and returns the recognized text in a clean, copyable format. The tool supports multiple languages, with primary emphasis on Chinese and English, but it also handles other common languages with reasonable accuracy. This makes it suitable for a wide range of use cases, from converting scanned business cards and handwritten notes to digitizing printed articles, menus, street signs, and textbook excerpts. The recognition engine runs entirely on the backend, so users do not need to download any software or worry about device performance limitations. One of the distinguishing features is batch processing capability. Users can upload multiple images at once, and the tool will process them sequentially, extracting text from each file and presenting the results in a single, consolidated interface. This is particularly useful for digitizing multi-page documents, series of receipts, or collections of presentation slides. After recognition, the extracted text can be copied to the clipboard with a single click, or exported directly as a Word document (.docx) for further editing, formatting, or sharing. The Word export preserves basic paragraph structure and line breaks, which reduces the need for manual refo
