What happens if the hotkey does not work? Check if the application is running. Look for the icon in your top menu bar. If the icon is missing, open it again from your Applications folder. Also, ensure you gave the app permission in your system settings under Security & Privacy.
Can I stop the app temporarily? Yes. Either quit the application from the menu bar or disable the hotkey in the settings menu.
Does this support Windows? This specific application is designed for macOS.
Is this service free? Yes. You can download and use the software at no cost.
If you experience trouble, open a new issue on the repository page. Provide details about your macOS version and describe the step where the problem occurs. Clear reports help identify fixes faster.
We believe in minimal data collection. This tool does not use trackers. It does not monitor your activity outside of the specific hotkey listener required to perform the conversion. Everything remains on your device.
