ICO Viewer Instructions
ICO Viewer is a free online ICO parser tool requiring no installation, running entirely inside your browser. Upload an ICO file and it will automatically detect all icons stored within, display real-time previews and complete file information.
Operation Steps
Upload ICO File Click the upload box and select an .ico file from local folders. You can also drag and drop ICO files directly onto the upload zone for fast uploads. This tool only supports ICO format; standard images like PNG/JPG cannot be parsed.
Preview All Icons Once loaded, every distinct icon size packed inside the ICO will be displayed separately for clear size comparison.
View Full File Info After upload you can check complete file metadata:
- File Name: Original file name
- File Size: Storage space occupied
- Dimensions: Pixel width and height of each icon
- Icon Count: Number of different icon sizes included in this ICO
Common Troubleshooting
- Upload failed? Ensure your file ends with .ico. Archives, photos and documents are not supported.
- Are my files sent to a server? All parsing runs locally in your browser. No files are uploaded to cloud servers to protect your privacy.
- What ICO file sizes are supported? Regular icon files work perfectly. Extra large ICO files may take a short while to load and render.
