Supports .ico and .cur files
ICO files are containers that hold multiple versions of the same icon at different sizes and color depths, allowing browsers and operating systems to choose the most appropriate version.
How it works
This tool examines your favicon.ico file and shows you detailed information about each image size contained within it. A properly formatted favicon.ico file typically contains multiple image sizes to support different use cases.
When you upload a favicon, the inspector extracts and displays each image variant, showing you the exact dimensions, bit depth, and format used. Icons up to 64x64 pixels are shown at their actual size without any scaling.
Simply drag and drop your favicon.ico file or click to select a file. The inspection happens entirely in your browser - no files are uploaded to any server.
