Favicons and the
ICO Standard

The ICO format is a legacy container for Microsoft Windows icons, but it remains the most compatible format for **website favicons** across all desktop browsers. A single ICO file can store multiple versions of an image at different sizes and bit depths, ensuring your logo looks sharp in both the address bar and as a shortcut icon.

Pixel-Perfect Clarity

XennConvert's ICO generator uses high-fidelity resampling to ensure that even at 16x16 pixels, your brand remains recognizable and clear.

Modern Workflow

Stop using insecure online generators that track your assets. Convert your private app icons locally with our zero-upload architecture.
