Format Explanation
- ICO Format: The standard icon container format for Windows. It stores multiple icon sizes (16x16 to 256x256) in a single file, allowing the OS to choose the best resolution for any context.
- Source PNG: Before packaging, your image is resized into a sequence of standard PNGs. We recommend using a high-res PNG with a transparent background for the best results.
- Website Favicon Tip: A favicon.ico usually includes 16x16, 32x32, and 48x48 sizes for broad browser compatibility. Place the file in your website's root directory.
