A square image works best (logo or icon)
Convert a PNG into a Windows .ico icon — the format Windows uses for application icons, shortcuts, and classic favicons. Your PNG is resized and packaged into the .ico structure locally in your browser, so nothing is uploaded, and transparency from the source is preserved.
What this tool does
- A Windows-compatible .ico built from your PNG
- Transparency preserved, so the icon has no solid box behind it
- Suitable for app icons, desktop shortcuts, and favicon.ico
- In-browser conversion — the PNG never leaves your device
How to use it
- Select or drop a PNG — a square one gives the cleanest icon.
- The browser resizes and packages it into the .ico format.
- Download the .ico file.
Frequently asked questions
- What size PNG should I use?
- Start square, at 256×256 or larger. Icons are square, so a square source avoids distortion, and a larger source downsizes cleanly. A tiny or oblong PNG looks rough as an icon.
- Will an ICO work on Mac or Linux?
- ICO is a Windows format. macOS uses .icns and Linux desktops usually use PNG icons, so an .ico is mainly for Windows apps and web favicons.
- Need several sizes in one file?
- Use the Favicon Generator, which bundles multiple icon sizes into a single .ico for different displays.
