Convert PNG to a real .ico file
Upload a PNG and choose which sizes to bake into the icon - the result is a genuine multi-resolution .ico file that works as a website favicon, a Windows app icon, or a desktop shortcut icon. Everything happens locally in your browser, so your image is never uploaded.
How to use it
- Choose a PNG image or drop it in.
- Pick the sizes you need (16/32/48 covers most favicons).
- Press Convert, then download your .ico file.
Which sizes should you pick?
For a standard website favicon, 16×16, 32×32 and 48×48 cover virtually every browser tab, bookmark bar and Windows shortcut use case. Add 128×128 or 256×256 if you also want a crisp, high-resolution icon bundled in the same file for app packaging or high-DPI displays.
Common uses
- Creating a favicon.ico for a website
- Making an icon for a Windows desktop application
- Converting a logo PNG for use in software installers
- Replacing a low-resolution or single-size .ico with a multi-size one
