ComfyUI-SaveAsICO

ComfyUI-SaveAsICO is a simple ComfyUI node which allows you to save generated images as .ICO files.

Features

• Saves a multi-size .ICO file with full alpha transparency (frames are stored as PNG, supported since Windows Vista)
• Offers three size presets:
  • Application: 64, 128, 256
  • Favicon: 16, 32, 48
  • Windows: 16, 24, 32, 48, 64, 128, 256
• Downscales each smaller size directly from the 256x256 source using Lanczos resampling
• Saves a 256x256 .PNG next to each .ICO, which is also shown as the node preview
• Supports batches, saving one .ICO and one .PNG per image
• Supports the filename prefix tokens %width%, %height%, %year%, %month%, %day%, %hour%, %minute%, %second%, and %batch_num%
• Passes the input images through to its output for further processing
