TinyIcon

A tiny windows icon file (.ico) creator.

Define your wanted resolutions, import image, save. Done!

Features

Multi-resolution icons: pick the sub-images your .ico should contain from 8×8 up to 256×256
Colour depth: 24-bit and/or 32-bit entries, selectable independently of each other
Import a source image (.png, .bmp, .jpg, .gif, .tiff) that gets downscaled into every sub-image
Non-square sources are fitted and centred with transparent padding, so the aspect ratio is kept
Full alpha transparency for 32-bit entries; 24-bit entries use a 1-bit mask
Automatic encoding per sub-image: PNG for 256×256 32-bit entries, classic DIB/BMP for the rest
Detail view with zoom (Ctrl +/-/*, or mouse wheel), pan (right mouse drag, right click recentres)
Keyboard shortcuts for the whole workflow: Ctrl+N (new icon), Ctrl+I (import image), Ctrl+S (save icon)
Remembers your window placement and the last resolution selection between runs
