What is a PNG to ICO converter?
ICO (Icon) files are special image containers used by web browsers to display a website's "favicon"—the small icon you see in browser tabs, bookmarks, and shortcuts. Unlike standard images, ICO files can store multiple sizes (e.g., 16x16, 32x32, 48x48) in a single file.
Converting PNG to ICO is essential for web developers and site owners. It takes your high-quality logo or graphic and packages it into the correct format that browsers expect, ensuring your brand looks sharp on every device.
Why do I need an ICO file?
- Browser Tabs: The tiny icon next to your page title is an .ico file.
- Bookmarks: When users bookmark your site, the favicon helps them identify it quickly.
- Desktop Shortcuts: Saving a website to a desktop creates a shortcut using the favicon.
- Professionalism: A custom favicon is a standard requirement for any polished, professional website.
How to create a Favicon online
- Upload Image: Select your logo (PNG or JPG recommended). A square image works best.
- Preview: See how your icon will look in a browser tab.
- Convert: The tool automatically generates the .ico file with standard sizes (16x16, 32x32).
- Download: Save the `favicon.ico` file and upload it to your website's root directory.
