About ICNS
Apple made ICNS for Mac OS 8.5 in 1998, and every Mac app still keeps its icon in one, in its bundle under Contents/Resources. Folders, disks and documents get theirs the same way.
An ICNS holds one icon drawn at several sizes, from 16 × 16 up to 1024 × 1024, with Retina copies at twice the pixels. Newer icons keep PNG or JPEG 2000 pictures inside, older ones packed pixels with a mask for their transparency.
No browser shows ICNS. Filepeek reads every picture in it, the biggest first, each a page named by its size, and Export saves the page on show as PNG with its transparency.

Questions
How do I open an ICNS file?
Drop it on this page or press Peek an ICNS. It opens at its biggest size, with every other size a page away.
How do I convert ICNS to PNG?
Open it, go to the size you want, then choose Export and Save as PNG, which keeps its transparency.
Where is a Mac app's icon?
In the app's Contents/Resources folder, as an .icns file, often AppIcon.icns. Drop that file on this page.
Is my icon uploaded?
No. It opens inside your browser and never leaves your device.
