About PNG to ICO

PNG is a versatile image format, especially for web graphics with transparency. However, for favicons or Windows desktop icons, the ICO format is specifically required. Our PNG to ICO converter makes it easy to take your high-quality PNGs and generate standard .ico files, including multiple resolutions within a single file for optimal display across different devices.

This tool operates with Client-Side Rendering (CSR). Your images are processed entirely within your web browser's memory, utilizing JavaScript to handle the conversion. This guarantees that your original artwork and converted icons are never uploaded to our servers, ensuring your privacy and data security.

How to Convert PNG to ICO

  1. Upload PNG: Drag your .png files into the drop zone, or click to select them from your computer.
  2. Review Files: Ensure your PNGs are listed correctly. You can convert multiple images in one go.
  3. Convert: Click "CONVERT TO ICO". The tool will generate different sizes (16x16, 32x32, 48x48, 256x256) from your source PNG.
  4. Download: Your new .ico files will be automatically downloaded, ready for use as favicons or desktop icons.
