Icon Requirements

Windows

ICO format with multiple embedded sizes for different contexts

macOS

ICNS format with all sizes for dock and app bundle

Linux

Multiple PNG sizes for different desktop environments

Best Practices:

Use a square image with transparent background for best results
Start with at least 1024x1024px for optimal quality across all sizes
Avoid thin lines and small text that may not scale well
Test your icon on different colored backgrounds

How to use the Electron Icon Generator

1Choose a square source image with a transparent background when your design requires it.
2Upload the image or drag it into the generator. Files up to 10 MB are supported.
3Review the preview, then generate the Electron icon package.
4Download the ZIP and place the Windows, macOS, and Linux assets in your application build directory.
5Reference the appropriate icon path in Electron Forge, Electron Builder, or your packaging configuration.

Common uses

Prepare a new Electron application for Windows, macOS, and Linux packaging.
Replace a starter icon with production-ready desktop application assets.
Generate consistent platform files without installing a separate icon conversion utility.
Create an organized icon package for Electron Forge or Electron Builder.

Choosing a source image

Use a high-resolution square image for the cleanest results. A 1024 by 1024 PNG provides enough detail for the largest macOS icon while also scaling down cleanly for Windows and Linux.

Keep important artwork away from the outer edge. Platform launchers may add masks, shadows, or visual padding around the final application icon.

Generated Electron icon formats

Windows packages use an ICO container with multiple resolutions. macOS packages use ICNS, while Linux applications commonly ship a collection of PNG files at standard sizes.

The downloaded ZIP separates these formats by platform so you can copy the correct file or directory into your packaging setup.

Private browser processing

Your source image is resized and packaged in the browser. It is not uploaded to the WebUtils server, which makes the tool suitable for unreleased application artwork.

Frequently asked questions

What image size should I use for an Electron icon?

A square 1024 by 1024 PNG is recommended. Smaller images can be converted, but they may appear soft at larger macOS icon sizes.

Does the generator create real ICO and ICNS files?

Yes. The package includes a multi-size ICO file for Windows, an ICNS file for macOS, and individual PNG sizes for Linux.

Is my icon uploaded to a server?

No. Resizing, format generation, and ZIP creation happen locally in your browser.

Can I use a JPEG source image?

The generator accepts image files, but PNG is the best choice when you need transparency around the icon artwork.
