Frequently Asked Questions
The converter generates 16x16, 32x32, and 48x48 pixel versions of your image, all packed into a single .ico file. These cover the most common display sizes for favicons and desktop icons.
A square PNG of 256x256 pixels or larger gives the best results. The converter will resize it to the needed dimensions. Non-square images will be fitted with preserved aspect ratio.
Yes. PNG alpha transparency is preserved in the ICO file. Your icon will have proper transparent areas that blend seamlessly with any background.
Save the file as favicon.ico and place it in your website's root directory. Browsers will find it automatically. You can also link to it explicitly with: <link rel='icon' href='/favicon.ico'>
For maximum compatibility, use ICO. While modern browsers accept PNG favicons, Internet Explorer and some edge cases still require ICO. Many sites provide both: an ICO fallback and PNG for modern browsers.
Yes, but square images work best for icons. Non-square images will be fitted into the square icon frame with the aspect ratio preserved and transparent padding added.
The generated ICO file can be used as an application icon, but embedding it in an .exe file requires a resource editor or build tool like Visual Studio.
No. The converter processes the PNG in your browser with no size restrictions. However, for icons, starting with a clean 256x256 or 512x512 PNG produces the best results.
