Why

Unlike iLovePDF, Smallpdf and most online PDF tools, nothing is uploaded to a server. Every operation happens client-side (in the browser or in the desktop app's WebView), so your documents stay on your machine. That makes it faster, private, and usable offline.

Develop

npm install
npm run dev        # http://localhost:1420
npm run build      # production web build → dist/
npm run typecheck  # tsc --noEmit

Deploy

See DEPLOY.md for web (Vercel/Netlify), macOS .dmg, and Windows .msi/.exe. See BUILD.md for native build prerequisites (Rust, Android SDK, signing).

Quick native build (all platforms via CI):

git tag v0.1.0 && git push origin --tags

GitHub Actions builds macOS + Windows + Linux + Android installers and attaches them to a release.

Privacy

• No backend. No analytics. No account.
• Files are processed in memory and never transmitted.
• AI features (Summarize/Translate) are optional and use a key/provider you choose; the free translation provider (MyMemory) and the local extractive summarizer need no key.

Security

See SECURITY.md for the security model and how to report vulnerabilities.
