The ICO to PNG Converter extracts all embedded images from Windows icon files and converts them to individual PNG files with preview and download capabilities. Simply upload your ICO file and instantly view all contained sizes (16x16, 32x32, 48x48, 64x64, etc.) as separate PNG images ready for download.
Perfect for:
- Web developers extracting favicons for different device sizes
- Icon designers needing individual PNG sizes from ICO files
- App developers converting Windows icons for cross-platform use
- UI/UX designers organizing icon assets by size
- System administrators extracting program icons for documentation
Upload your ICO file, choose your preview layout, and download individual PNG images or bulk download all sizes at once. All processing happens client-side for complete privacy and speed.
How It Works
Our ICO to PNG Converter uses advanced binary parsing to analyze Windows icon file structure and extract embedded images. Here's the conversion process:
- ICO File Analysis: Parse the ICO header and directory structure to identify all embedded images and their properties
- Image Detection: Scan each embedded image to detect format (PNG, BMP) and extract size information (16x16, 32x32, etc.)
- Format Conversion: Extract embedded PNG images directly or convert BMP data to PNG using HTML5 Canvas
- Preview Generation: Create visual previews of each extracted PNG image with size labels and quality indicators
- Download Preparation: Package each PNG with proper filenames and provide both individual and bulk download options
All conversion happens locally in your browser using pure JavaScript – your ICO files never leave your computer. The tool handles both modern PNG-embedded ICO files and legacy BMP-based icons with full quality preservation.

Frequently Asked Questions
What ICO file formats and image sizes does this converter support?
This converter supports all standard Windows ICO files including modern PNG-embedded icons and legacy BMP-based icons. It extracts all common sizes including 16x16, 32x32, 48x48, 64x64, 128x128, and 256x256 pixels. The tool automatically detects embedded PNG images and converts BMP data to PNG format while preserving transparency and color depth.
Is ICO to PNG conversion secure and does it protect file privacy?
Yes, all ICO processing happens entirely in your browser using client-side JavaScript. Your ICO files never leave your computer or get uploaded to any server. The tool uses HTML5 FileReader API and Canvas for local processing, ensuring complete privacy and security for sensitive icon files and proprietary graphics.
Can this tool extract all sizes from a single ICO file simultaneously?
Absolutely! The converter automatically detects and extracts all embedded images from ICO files, displaying each size as a separate PNG preview. You can download individual sizes or use the bulk download feature to get all PNG files at once. Each extracted image maintains its original quality and transparency.
What's the difference between embedded PNG and BMP images in ICO files?
Modern ICO files often contain embedded PNG images for better compression and transparency support, while older ICO files use BMP format. Our converter automatically detects the format and handles both types: PNG images are extracted directly, while BMP data is converted to PNG using canvas rendering to ensure consistent output format.
Are there file size limits and what download options are available?
The tool supports ICO files up to 10MB in size, which covers virtually all icon files. Download options include individual PNG files with customizable filenames (by size, index, or original name), bulk download of all sizes, and optional ZIP packaging. All downloads maintain original image quality and proper PNG formatting.
