## Questions

### Do files leave my computer?

Files, pasted text and generated results are processed in this browser. They are not uploaded to a conversion server. Engine downloads can require internet access; large operations depend on the memory and CPU available on this device.

### Can I convert files without internet access?

The website and required engine assets must load first. Processing runs on this device; a fresh visit or an uncached engine still requires internet access.

### How long can I download completed results?

Results stay in this browser tab until you remove them or reload/close the page. Download anything you want to keep. Saved downloads are independent of the browser workspace.
