About PDF Toolkit

PDF Toolkit is an open-source Android app for working with PDF documents on the device itself. It combines document management (merging PDFs and images, splitting, compressing, reordering, rotating, extracting and deleting pages), conversion (images to PDF, PDF to images, HTML to PDF, camera scanning) and editing (annotating, signing, filling and flattening forms, locking, unlocking and watermarking). It also includes OCR for pulling text out of PDF pages, plus image compression, resizing, format conversion and EXIF metadata removal.

The project states that processing happens on-device with no cloud or servers, no internet permission, no account requirement and no data collection or tracking. It is distributed through F-Droid, Google Play and GitHub Releases as separate build flavors; the Play Store flavor uses Google ML Kit OCR, while the F-Droid and opensource flavors use Tesseract and are described as free of proprietary dependencies. The app is Android-only, and pricing is not stated in the source.
