Frequently asked questions
What sizes should an .ico include?
Common: 16, 32 for classic tabs; 48, 64 optional; 128 and 256 for high-DPI/Windows scaling.
PNG vs ICO?
Modern browsers accept PNG favicons. An .ico bundles multiple sizes in one file, which still helps in some environments.
Best source image?
Square logo (≥512×512). Transparent PNG is ideal. Use Pad/Fit if your logo isn’t square.
What does the ICO Generator do?
Build a multi-size ICO favicon from a JPG, PNG, or other supported source image.
How should I interpret a ICO Generator result?
Read the displayed labels and validation messages together, then verify important findings against the original source. The result is a practical aid, not proof beyond the data it can inspect.
