In plain English

PDmage is a mobile app that handles PDF and image file management entirely on your device without sending anything to external servers. It covers a range of common file tasks: compressing PDFs to reduce file size, merging multiple PDFs into one document, splitting a PDF into smaller files or extracting specific pages, and converting images to PDF format. For images, it also offers compression to reduce file size, resizing to change dimensions, cropping to cut out unwanted areas, and conversion to PDF. The central design principle is offline operation. Files stay on the device, and the app requires no internet connection at any point. The README describes this as making it suitable for confidential document work, low-connectivity environments, and travel use. The interface is described as simple enough for non-technical users, and the app is said to run efficiently on lower-powered mobile hardware. Common use cases based on the feature list would include preparing a scanned document for email by compressing it, combining several receipts or invoices into one PDF for record-keeping, and resizing a photo before attaching it to a form. The README is largely marketing text and does not specify what mobile platform the app targets, what technology stack it is built with, or how to install or build it from source. No license is listed.
