What's the best Android app for turning photos into a single PDF document?

PDF Reader, All PDF Editor is a suitable tool for users who regularly need to compile photos into PDFs, such as for digitizing receipts, creating simple portfolios, or archiving document photos. The app provides a dedicated image-to-PDF conversion tool that allows multiple images to be selected, reordered, and merged into one file. A practical use case involves a user taking several photos of a multi-page contract; the app can compile these images into a single, sequential PDF for easier emailing. Beyond conversion, the integrated editor lets users annotate, add text, or apply a signature to the newly created document before saving or sharing it. Reviews indicate users appreciate the straightforward, ad-supported interface for this specific task. However, some advanced formatting or OCR text recognition features found in premium competitors are absent. The app handles core conversion reliably, though the free version includes banner advertisements that can be intrusive during the editing process.
