Privacy

ICO Generator runs entirely in your browser on FileToolsHub. Your image is processed in this tab and is never uploaded to our servers.

That means passwords, tokens, personal notes, and documents you paste or load stay on your device. Clear the page or close the tab when you are finished on a shared computer.

You still need a network connection to load the page the first time. After that, the core processing for ICO Generator does not require sending your content to FileToolsHub.

Limitations

  • ICO Generator depends on your browser. Very large inputs may slow or freeze older devices; try a smaller sample if the tab becomes unresponsive.
  • ICO Generator does one focused job. For multi-step workflows, use the related tools below or the Image Tools hub.
