Frequently asked questions
- Is the ICO converter free?
- Yes, completely free with no registration required. Convert unlimited images to ICO format. All processing happens locally in your browser.
- What is a favicon.ico file?
- A favicon.ico is a special image file that contains one or more small icons, used by web browsers to display in tabs, bookmarks, and shortcuts. ICO format can bundle multiple sizes into one file.
- Why include multiple sizes?
- Different browsers and devices use different favicon sizes. 16x16 for tabs, 32x32 for bookmarks, 48x48 for Windows taskbar, 180x180+ for iOS home screen icons. Including multiple ensures crisp display everywhere.
- Do I need technical knowledge?
- Basic HTML knowledge helps. After downloading favicon.ico, upload it to your website root, then add the link tag to your HTML head section. We provide the exact code to copy.
- What image formats can I convert?
- Upload JPG, JPEG, PNG, WebP, GIF, and SVG files. The tool converts them to ICO format which all modern browsers support.
- Why is my favicon blurry?
- Blurry favicons usually means the original image is low resolution. Our tool maintains quality, but starting with a higher resolution image will produce better results. Make sure to include larger sizes (128px, 256px) for retina displays.
- Can I use a photo as favicon?
- Yes, but simple logos or icons work better. At 16x16 pixels, photos become barely recognizable. Consider using the main brand element or first letter styled nicely.
- Are my images safe?
- Absolutely. The conversion happens entirely in your browser using JavaScript. Images are not uploaded to any server. Your files stay on your device.
