The sizes you choose
Anything from 16 to 256 pixels, in one icon file.
Make a Windows .ico from any picture or SVG, with exactly the sizes you need from 16 to 256 pixels, and a macOS .icns when you need one.
How it works
Open Tools › Images › Windows icon and choose a picture or SVG.
Tick the sizes you want, and whether to crop to a square.
Use the .ico for your app, shortcut or folder.
What you get
Anything from 16 to 256 pixels, in one icon file.
SVGs are redrawn for each size instead of being scaled.
Non-square pictures get transparent margins, or crop them to a square.
Icons that Windows, resource compilers and icon editors all accept.
