❓ FAQ
Does the image need to be square?
Conversion still works, but non-square images may be cropped or stretched. A square source image is strongly recommended.
Why are multiple sizes needed in an ICO file?
Different contexts use different sizes: browser tabs use 16 px, bookmarks use 32 px, and the Windows taskbar uses 48 px.
Is the transparent background preserved?
Yes. The ICO format supports transparency.
Are my files uploaded to a server?
No. All processing happens locally in your browser.
