🖼️ What is an ICO File?

An ICO file is a graphics format used for icons in Microsoft Windows. It can contain multiple images at different sizes (16×16, 32×32, 64×64, 256×256) and color depths within a single file. ICO files are commonly used for application icons, website favicons, and desktop shortcuts.

🌐 Why Convert ICO to PNG?

PNG is a universally supported image format that works across all operating systems, browsers, and design applications. Unlike ICO, PNG is not limited to Windows environments. PNG supports full transparency (alpha channel) and lossless compression — making it ideal for web graphics, app design, and digital art.

Converting ICO to PNG is useful when you want to use an icon image in web projects, edit it in design software like Photoshop or Figma, or share it with users on non-Windows systems.

🔒 Is My File Safe?

Completely. This converter runs entirely in your browser using JavaScript — no files are ever uploaded to a server. Your ICO file stays on your device at all times, and once you close the page, nothing is stored or accessible. This makes it one of the most private image converters available.

📐 Does It Preserve Quality?

Yes. The conversion uses your browser's built-in Canvas API to render the ICO image and export it as a PNG — preserving the original pixel dimensions and transparency. The result is a lossless, high-quality PNG file ready for immediate use.
