PDF Toolbox started as a small app to remove passwords from PDF files and has evolved into a comprehensive PDF management solution. The app provides various PDF manipulation capabilities entirely offline.

The app includes features for merging multiple PDFs, splitting PDF documents, compressing file sizes, protecting PDFs with passwords, unlocking secured PDFs, optical character recognition (OCR), rotating pages, resizing documents, and creating PDFs directly from camera captures. All processing occurs locally on the device without requiring internet connectivity.

The application operates completely offline, ensuring user privacy and security by processing all PDF files locally on the device rather than uploading them to external servers. This approach eliminates the need for internet connectivity during PDF operations.

The primary benefit is maintaining complete privacy and security since files never leave the user's device. The app serves users who need to manipulate PDF documents while ensuring their sensitive information remains confidential and secure.

The target users include anyone needing PDF manipulation tools with privacy concerns, as the app requires no internet connection and processes files locally. It's designed for users who prioritize data security and want to avoid uploading sensitive documents to cloud services.
