There are lots of questions relating to setting icons using electron-packager but none of the answers have worked for me – maybe the answers are out of date or not clear – but I need to ask again.

I am building on OSX for OSX & Windows. I've tried at least 20 variations on specifying the icon for electron-packager (the full cmd set is below). I've tried referencing icons withing the app folder (app/assets/WIN_logo.icns) as well as in an "icons" folder at the project root (icons/assets/WIN_logo.icns); I've tried using quotation marks, leaving off the extension and other stuff I can't even recall.

So please, can someone tell me, given the directory structure below, how I specify the icon for electron-packager to use.

-icon=assets/WIN_logo.icns
-icon=assets/WIN_logo.ico

  "package-mac": "electron-packager . --overwrite --tmpdir=false --platform=darwin --arch=x64  --prune=true --out=release-builds -icon=assets/WIN_logo.icns",
  "package-win": "electron-packager . --overwrite --tmpdir=false --platform=win32 --arch=ia32 --asar=true  --prune=true --out=release-builds -icon=assets/WIN_logo.ico"

For mac

1/ verify that the name of the icon is icon.icns 2/ verify that the icon size is at least 512x512px 3/ change --out=release-builds by --out=build

For windows

1/ verify that the name of the icon is icon.ico 2/ verify that the icon size is at least 256x256px 3/ change --out=release-builds by --out=build

source : https://www.electron.build/icons

these steps works for me.

Change -icon=assets/... to --icon=./assets/...

The icon argument should have two hyphens at the start and the path should start with ./.

[1] Icon path: The icon path is not relative to the project directory, but to the current location. (For me, the problem was that I assumed the former, as I thought it made sense with less redundancy.) In any case, one has to run either:

electron-packager projectDirPath outputName ... --icon=projectDirPath/iconPath/icon.png

Or if you are in the project directory:

electron-packager . outputName ... --icon=iconPath/icon.png

[2] Icon format: For macOS, both icon.png and icon.icns is accepted. For Windows, both icon.png and icon.ico is accepted.

[3] Icon size: For macOS, the dimensions must be at least 512x512px. For Windows, the dimensions must be at least 256x256px.
