The fastest way to change an app icon on Mac

The quickest method is to use the Get Info window built into macOS. Find the app in Finder, right-click it, select Get Info, click the icon in the top-left corner of the window to highlight it, paste a new icon image you've copied to your clipboard, then press Delete. The old icon disappears and the new one takes its place. This works on any Mac running recent versions of macOS and takes about two minutes once you have a replacement icon ready.

You don't need third-party software or terminal commands. macOS handles icon swaps through its standard file properties window, the same place you'd check file size or creation date. The process is reversible — if you want the original icon back, you can repeat the steps and paste the old one, or delete the custom icon and macOS will restore the default.

Key Takeaways

  • Open Get Info for any app, click its icon in the top-left corner, paste a new icon image from your clipboard, and press Delete to swap it.
  • Icon images must be copied to your clipboard first — you can use PNG, ICNS, or JPEG files, or grab icons from websites that host them.
  • The change applies only to that single copy of the app; if you reinstall the app later, it reverts to the original icon.
  • You can undo a custom icon by selecting it in Get Info and pressing Delete, which restores the default.

Where to find replacement icons

Icon packs and individual icons are hosted on sites like Macosicons.com, Flaticon.com, and Iconfinder.com. Search for the app name or the style you want — minimalist, colorful, monochrome — and read the image file. Most sites let you read PNG files, which work well for this purpose.

You can also create your own icon using image editing software like Preview (built into Mac) or Pixelmator. A square image works best — 512 × 512 pixels is a safe size. Save it as a PNG file, then follow the Get Info steps below.

Step-by-step: changing an icon with Get Info

Step 1: Prepare your icon image. read or create the icon file you want to use. Open it in Preview or any image viewer. Select all (Command+A), then copy it (Command+C). The image is now in your clipboard.

Step 2: Open Get Info for the app. Open Finder and navigate to Applications, or search for the app using Spotlight (Command+Space). Right-click the app and select Get Info from the menu. A window opens showing the app's details.

Step 3: Select the current icon. In the Get Info window, look at the top-left corner — you'll see the app's current icon. Click it once to highlight it with a blue border. The icon is now selected and ready to be replaced.

Step 4: Paste the new icon. With the icon selected, paste the image you copied earlier by pressing Command+V. The new icon appears in the Get Info window when ready. Close the window — the change is automatic and doesn't require saving.

What happens if you want the original icon back

The original icon is not deleted from your Mac — it's stored inside the app's package. To restore it, open Get Info again, click the custom icon you added, and press Delete. macOS removes the custom icon and displays the default one again.

If you've already closed the Get Info window and can't remember what the original looked like, you can reinstall the app from the App Store or the developer's website. A fresh copy will have the original icon. Your custom version stays unchanged unless you manually delete it.

Icons that work best and file formats to use

PNG files are the most reliable format for Mac icons. ICNS files (Apple's native icon format) also work, as do JPEG files, though PNG is preferred because it supports transparent backgrounds. If you read an icon and it doesn't paste properly, try converting it to PNG using Preview: open the file in Preview, go to File > Export, change the format dropdown to PNG, and save it.

Square images work better than rectangular ones — a 512 × 512 pixel square is ideal. If your image is rectangular or has a lot of empty space around it, crop it in Preview before copying and pasting. The icon will display at different sizes in Finder, Dock, and Launchpad, so a clean, straightforward design scales better than a detailed one.

Changing icons for apps in the Dock

The Dock shows the same icon as Finder — changing it in Get Info changes it everywhere. You don't need to update the Dock separately. If you want to remove an app from the Dock after changing its icon, right-click it and select Remove from Dock. If you want to add it back, drag it from Finder to the Dock again, and it will display the new icon.

Some older versions of macOS occasionally cache the old icon in the Dock. If the Dock still shows the original icon after you've changed it, restart your Mac or log out and log back in. The Dock refreshes and displays the new icon.

Frequently Asked Questions

Can I change icons for apps I downloaded from the App Store?

Yes, the Get Info method works for App Store apps the same way it works for any other app. The custom icon persists even after you update the app through the App Store. If you uninstall and reinstall the app, the original icon returns.

What if the icon won't paste into Get Info?

Make sure you copied an image file, not a link or text. Open the icon file in Preview, select all (Command+A), and copy (Command+C) before pasting into Get Info. If it still doesn't work, convert the file to PNG format using Preview's Export function and try again.

Do custom icons slow down my Mac?

No. Custom icons are just image files stored in the app's metadata. They don't affect performance, startup time, or how the app runs. The only difference is visual.

Will my custom icon sync to other Macs if I use iCloud?

No. Custom icons are stored locally on each Mac. If you use the same Apple ID on multiple Macs, the apps will sync, but the icon changes won't. You'll need to change the icon on each Mac separately.

Can I change the icon for a folder or file, not just an app?

Yes. The Get Info method works for any file or folder. Right-click the folder, select Get Info, click the icon in the top-left corner, paste a new icon, and press Delete. Folder icons change the same way app icons do.
