Frequently asked questions
What image formats can I convert to ICO?
Any common raster image your browser can read works, including PNG, JPG/JPEG, WebP and GIF. PNG or WebP with transparency give the cleanest favicon because the areas around your icon stay transparent.
Are my images uploaded to a server?
No. This image to ICO converter runs 100% in your browser. Your image is read and converted locally on your device and is never uploaded, stored or sent anywhere.
What sizes does the .ico file contain?
The generated .ico packs three icon sizes in one file: 16x16, 32x32 and 48x48 pixels. Browsers and operating systems automatically pick the sharpest size for tabs, bookmarks and shortcuts.
Will my image be stretched or distorted?
No. Your image is scaled to fit (contain) and centered on a transparent square for each size, keeping the original aspect ratio. Nothing is cropped or stretched.
Is this a real ICO file for a favicon?
Yes. The tool hand-assembles a standards-compliant multi-size ICO file with a proper header and PNG-based icon entries, so it works as a favicon.ico and as a Windows icon.
What image should I use for the best favicon?
Use a square, high-contrast image with a simple design and, ideally, a transparent background. Small details can get lost at 16x16, so keep the artwork bold and centered.
