Frequently Asked Questions

Which sizes does the generated ICO file contain?
For maximum compatibility, every generated .ico file includes the four standard sizes: 16x16, 32x32, 48x48 and 256x256. This keeps your icon sharp on the desktop, taskbar and in different views.
Do I need to upload a square image?
No. The tool automatically fits your image to a 1:1 aspect ratio and centers it to meet ICO format requirements. For the best results, we recommend an image that is roughly square.
Is this service really private?
Absolutely. All file processing happens entirely inside your browser — images are never sent over the internet or stored anywhere. What happens on your computer stays on your computer.
Where can I use the generated .ico file?
The most common use is as a website favicon (the browser tab icon). It can also be used for Windows desktop shortcuts, folder icons and application icon resources.
