Which operating systems are supported?

Windows 10 and 11 (64-bit), macOS on Apple Silicon and Intel, and Linux (AppImage and .deb).

Does PDFTara Studio work offline?

Yes. The PDF tools run on your device. The optional AI Copilot can connect to locally hosted models such as Ollama or LM Studio.

Why does Windows or macOS show a security warning?

The app is not yet code-signed. On Windows choose "More info" and then "Run anyway". On macOS right-click the app, choose "Open", then confirm.

How do I know if my Mac is Apple Silicon or Intel?
