Frequently Asked Questions
Which sizes should I include?
For a website favicon, include at least 16×16 and 32×32. For Windows app icons, also add 48×48 and 256×256. Including multiple sizes ensures the OS picks the best resolution for each display context.
What image formats are supported as input?
Any format your browser can render: PNG, JPG/JPEG, WebP, GIF, BMP, and SVG. For best results use a square image with transparent background (PNG).
Is this ICO compatible with all browsers and Windows?
Yes. The generated ICO uses embedded PNG data per size, which is supported by all modern browsers and Windows Vista and later.
Is my image uploaded to a server?
No. All conversion is done locally in your browser using the Canvas API. Nothing is uploaded.
