FAQ

What sizes are inside the .ico file?

Layers of 16, 32, 48, 64, 128 and 256 px are packed into one file, so Windows picks the right one for each view.

Why does my icon look blurry?

Small sources upscale poorly. Start from a square image of at least 256 px — 512 px or more is ideal.

Is my image uploaded?

No. The icon is built with a canvas in your browser and never leaves your device.
