Offline PDF Toolkit: Bindery

EduPlay Connect

About this app

Bindery is a privacy-focused PDF toolkit for Android — every core tool runs entirely on your device. No cloud uploads, no accounts, no ads, no trackers. Your existing documents never leave your phone.

FEATURES

📖 Booklet Maker — turn any PDF into a foldable, print-ready booklet (a rare fully offline Android tool)
🔗 Merge — combine multiple PDFs into one
🔄 Rotate & reorder pages
🔢 Page numbering
📷 Scan to PDF — turn photos into PDFs with automatic perspective correction
💧 Watermarking
📄 Built-in reader — landscape mode, night mode, fast rendering

WHY IT'S PRIVATE

Most "free" PDF tools quietly upload your files to a server to do the actual work. Bindery doesn't — merging, scanning, converting, and booklet-making all run locally, using your device's own processor. The only feature that touches the network is optional: importing a PDF from a URL you provide. Everything else — everything that happens to files already on your phone — stays local.

OPEN SOURCE

Bindery is licensed under GPL-3.0 — the source code is public, so you can verify these claims yourself instead of just trusting them.
