Convert ICO to PNG
What is ICO?
ICO
ICO stores multiple bitmap images at various sizes and color depths (1-bit to 32-bit with alpha) in a single file. Designed for Windows application and website favicons. Contains multiple representations (16×16, 32×32, 48×48, 256×256) for different display contexts. Can store both BMP and PNG formats internally. Maximum 256×256 pixels per image. Supports transparency.
- ICO uses lossless compression for perfect quality image storage
- Opaque image data converts to PNG without utilizing transparency features
- No transparency support—requires opaque backgrounds
What is PNG?
PNG
PNG uses lossless Deflate compression, preserving exact pixel values without quality loss. Supports full alpha channel transparency (256 levels) unlike JPG. Ideal for graphics with sharp edges, text, logos, or images requiring transparency. Typically larger file sizes than JPG for photographs due to lossless compression. Maximum resolution 2,147,483,647×2,147,483,647 pixels. Supports indexed color palettes and metadata chunks.
- PNG uses lossless compression for perfect quality image storage
- Alpha channel transparency requires background color for ICO conversion
- DEFLATE compression reduces file size without data loss
- Supports 24-bit RGB color (16.7 million colors)
- Universal browser and device support—no compatibility concerns
