PaperWise: Scan Images to PDF

PaperWise is a productivity app by Aishwarya Prateek that turns images from your camera or gallery into PDF documents. It is a free, open-source tool designed for quick scanning of documents, receipts, and notes, with a focus on privacy and simplicity. The app lets you select multiple images, arrange them, and then export a single PDF file, all without displaying ads or requesting unnecessary permissions.

At its core, PaperWise is about giving you control over your scans. You can pick photos from your gallery or capture new ones directly within the app, then reorder, crop, or remove images before generating the final document. You also have options to choose the page size—such as A4, Letter, or Fit to Image—and to adjust the PDF quality to balance file size against clarity. This makes it useful for students digitizing notes, professionals archiving paperwork, or anyone who wants a lightweight scanning tool.

The app is especially appealing to privacy-conscious users because all files are saved locally on your device, meaning you keep ownership of your data. It also includes dark and AMOLED Black themes for comfortable use in low-light settings. With a small footprint of 9.7 MB and support for Android 5.0 and up, PaperWise is a straightforward choice for beginners who need a reliable, no-frills way to create PDFs from images.
