Overview This app is a powerful tool for converting PDF files into Markdown format without requiring an internet connection. After conversion, only a single Markdown file is generated. Images embedded in the PDF will be processed and converted into text where possible; if no text can be recognized, they will not be displayed. Whether handling large or small PDFs, the app ensures smooth conversion, making it easier to manage and share your documents. Key Features - Offline Conversion: Convert PDF files to Markdown anytime, anywhere without the need for internet access. - No File Size Limits: Supports PDF files of any size, with no restrictions. - File Output: Generates a single Markdown file with a clear and structured format. - Easy Sharing: Quickly share the Markdown file via AirDrop or other commonly used apps. - User-Friendly: A simple and intuitive interface that makes file conversion and sharing effortless, even without technical expertise. This app is continuously being improved. It currently provides basic features such as extracting text from PDF files and sharing the results. If the PDF consists of images, the app will attempt to recognize text within those images; if recognition fails, the corresponding content will not be displayed. All operations are performed locally on your device, ensuring your data remains private and secure. Thank you for your understanding regarding any imperfections.
