Everything you need

📄

Two-panel view

Load odd and even pages into separate panels — via drag & drop or the open dialog.

🔀

Smart interleaving

Pages are automatically interleaved in the correct order. Optionally reverse even pages if needed.

🗂️

Automatic pairing

Drop two files at once — the app detects which file belongs where based on the filename.

⚡

Batch mode

Watch a folder — new PDF pairs are detected and merged automatically.

🔒

100% privacy

Fully offline. No data leaves your Mac. No trackers, no cloud services.

🍎

Native macOS

Built with SwiftUI for macOS 13+. Fast, lightweight, and native-feeling.
