Elephicon is a free, open-source Mac utility that converts PNG images into native Apple .icns and Windows .ico icon files with a single drag-and-drop.
What is Elephicon?
Elephicon is a lightweight macOS app that takes a PNG and spits out production-ready icon bundles — the .icns format macOS expects for application icons and the .ico format Windows software still requires. If you've ever shipped a side project, a menubar app, or a Tauri/Electron build and found yourself wrestling with iconutil at 1 a.m., this is the tool that makes that pain disappear.
The workflow is genuinely frictionless. Drop a high-resolution PNG (ideally 1024 × 1024 px) onto the window, pick your output format — or generate both at once — and you're done. No Terminal incantations, no third-party icon sets, no Photoshop export panel to configure. Elephicon handles all the internal resolution slices that .icns and .ico demand, so the finished file works correctly at every size from 16 px to the full retina canvas.
What does Elephicon do best?
Elephicon's greatest strength is turning a one-PNG source into a correctly-structured multi-resolution icon bundle without any friction or configuration. Where a tool like GIMP or Pixelmator Pro requires you to manually build icon canvases at each required size, Elephicon does the resizing and packaging internally in a few seconds.
Because it targets the precise formats that Apple's own toolchain and Windows installers expect — not just any image file renamed with a new extension — the icons it produces load cleanly in Finder, the Dock, App Sandbox, and Electron's build pipeline alike. I've shipped several small utilities with icons created entirely in Elephicon, and none have triggered the dreaded blurry-icon syndrome that plagues hand-rolled attempts.
- Drag-and-drop interface — no menus to navigate, no save dialog to dismiss
- Dual-format output — generates both .icns and .ico in one pass when needed
- Multi-resolution bundling — all required size variants are created automatically from your single source PNG
- Zero configuration — sensible defaults mean the first run is also the correct run
- Native Apple Silicon support — runs on both arm64 and x86-64 Macs
Is Elephicon free?
Yes — Elephicon is completely free to download and use. It is published as open-source software on GitHub under a permissive licence, so you can inspect the code, build from source, or install via Homebrew Cask with a single command. There are no in-app purchases, no watermarks on exported icons, and no usage caps.
Who should use Elephicon?
Independent Mac developers and anyone shipping cross-platform desktop apps will get the most out of Elephicon. If you're building with Tauri, Electron, or plain Swift and need to hand off a polished icon file to your build system, Elephicon removes what would otherwise be a small-but-annoying manual step. Designers handing off assets to developers will also find it useful — export your final logo as a 1024 px PNG from Figma or Sketch, run it through Elephicon, and the developer gets an immediately usable asset.
It's less interesting if you need deep icon-editing capabilities — for that, something like Pulsar or dedicated icon editors gives you per-size fine-tuning that Elephicon intentionally omits. Elephicon is a converter, not an editor, and it makes no apology for that focus.
What are the best Elephicon alternatives?
The closest comparable free tools are Image2icon (freemium, broader format support, photo-effect layer) and the command-line combination of sips + iconutil that ships with Xcode Command Line Tools. For Windows-only .ico generation, GIMP's export plugin or online converters get the job done, but neither produces the .icns side of the equation. If you're already in a Node.js build pipeline, the png2icons npm package does something similar programmatically. Elephicon wins over all of these when the priority is a native Mac GUI that's fast, offline, and free of account sign-ups.
How does Elephicon compare to Image2icon?
Image2icon has a richer feature set — photo effects, custom text overlays, folder icon replacements — but many of those features sit behind a paid upgrade. Elephicon does one thing and does it for free, forever. For developers who only need the raw conversion step and want a tool that installs in seconds and never asks for money or permissions, Elephicon is the cleaner choice. Image2icon is better for designers who want to stylise icons visually before exporting.
