Zen PDF is a lightweight, offline PDF editor built with Tauri and React. It lets you merge, split, reorder, rotate, compress, and export PDFs — locally on your machine with no network calls.

• Merge multiple PDFs into one document
• Split by page ranges or into single‑page PDFs
• Reorder pages via drag‑and‑drop and rotate per‑page
• Compression presets for output size/quality trade‑offs
• Export a single combined PDF or multiple PDFs (ZIP)
• Themes for the UI (e.g., Default, Gruvbox, Tokyo Night, Catppuccin, Dracula)
• Run OCR to make scanned PDFs searchable (desktop app)
• Search across loaded pages (native + OCR text) with highlights and match navigation
• Full page view and thumbnail grid view
• Zoom in/out in the full page view

• Install dependencies: npm install
• Run in development: npm run dev (starts Tauri dev with Vite)
• Build a desktop app: npm run build

Note for macOS signing: the Tauri config sets a placeholder signing identity. To produce signed binaries, replace the placeholder in src-tauri/tauri.conf.json:46 with your own Apple Developer ID Application identity or remove the field to sign locally via your keychain settings.

Notes

• OCR is available in the desktop app. The macOS bundle includes the Tesseract runtime and English language data so OCR runs locally without network calls.

• Requirements
  • Xcode Command Line Tools: xcode-select --install
  • Rust (via rustup) and Node.js 18+ with npm
  • Tauri CLI: npm install -g @tauri-apps/cli (optional; npm run build will also invoke it)
• Develop
  • npm run dev (runs Vite + Tauri dev)
• Build (unsigned by default)
  • npm run build (produces a .app/.dmg under src-tauri/target/release)
  • To sign/notarize, set a valid signingIdentity in src-tauri/tauri.conf.json or sign via your keychain. Unsigned builds may require removing quarantine: xattr -dr com.apple.quarantine "Zen PDF.app"

• Requirements
  • Rust (stable) and Node.js 18+ with npm
  • System packages
    • Debian/Ubuntu: sudo apt update && sudo apt install -y libwebkit2gtk-4.1-dev libgtk-3-dev libayatana-appindicator3-dev librsvg2-dev patchelf
      • If libwebkit2gtk-4.1-dev isn’t available, try libwebkit2gtk-4.0-dev.
      • If libayatana-appindicator3-dev isn’t available, try libappindicator3-dev.
    • Arch: sudo pacman -S --needed webkit2gtk gtk3 libappindicator-gtk3 librsvg patchelf
    • Fedora: sudo dnf install -y webkit2gtk3-devel gtk3-devel libappindicator-gtk3 librsvg2-devel patchelf
    • openSUSE: sudo zypper install -y webkit2gtk3-devel gtk3-devel libappindicator3-gtk3 librsvg-devel patchelf
• Develop
  • npm run dev
• Build bundles
  • tauri build --bundles appimage,deb (Debian/Ubuntu) or tauri build --bundles appimage,rpm (Fedora/openSUSE)
  • Outputs land under src-tauri/target/release/bundle/
• Notes
  • The dmg bundle target in tauri.conf.json is macOS-only and ignored on Linux. Pass Linux bundles explicitly as above.
  • AppImage portability depends on glibc; for widest compatibility, build on the oldest distro/version you intend to support.
  • ARM/aarch64 is supported if the matching system packages are available. Prefer building on the target architecture.

• error while loading shared libraries: libwebkit2gtk-4.1.so.0 — install WebKitGTK runtime/dev packages (see above; may be 4.0 on some distros).
• patchelf: command not found — install patchelf using your distro’s package manager.
• Blank or failing window on start — ensure webkit2gtk and gtk3 are installed; try launching from a terminal to see errors.

• Building Intel binaries from Apple Silicon is not recommended due to Apple toolchain and WebKit constraints. Build natively on an Intel Mac for the best results.
