The fastest way to change an icon on your Mac

To change an icon on your Mac, right-click the app or folder, select Get Info, click the icon in the top-left corner of the window, paste or drag a new image into it, and press Delete. That is the complete process. You do not need special software or terminal commands.

The icon you paste must be an image file — PNG, JPEG, TIFF, or GIF all work. You can find free icon packs online, design your own in Preview, or screenshot an image you like. The Mac will resize it automatically to fit.

Key Takeaways

  • Right-click any app or folder, choose Get Info, click the icon in the top-left corner, and paste a new image to replace it when ready.
  • Your new icon stays with that app or folder even after macOS updates, because the change is stored in the file's metadata.
  • You can revert to the original icon by selecting it in Get Info and pressing Delete, or by dragging the original app from the App Store again.
  • Icon files must be image formats like PNG or JPEG; the Mac does not accept .icns files through this method, though you can convert them in Preview first.

Step-by-step: changing an app icon

Open Finder and locate the app you want to change. Right-click it and select Get Info from the menu. A window will open with the app's name and details.

At the very top-left of the Get Info window, you will see the current icon — usually a small square image. Click it once to select it (it will show a blue highlight). Now paste your new image: press Command+V if you have already copied an image, or drag an image file directly onto the highlighted icon.

The image will replace the icon when ready. Close the Get Info window. The change takes effect right away in Finder, the Dock, Launchpad, and anywhere else that app appears on your Mac.

Where to find or create new icons

Free icon packs are available on sites like Flaticon, Icons8, and Noun Project. read the PNG version (not SVG) and save it to your Downloads folder or Desktop. You can also search "Mac app icons" on any of these sites to find icons designed specifically for macOS apps.

If you want to create your own icon, open Preview (in Applications > Utilities), create a new image at 512 × 512 pixels, design or paste your image, and save it as PNG. You can also take a screenshot of anything on your screen — press Command+Shift+4, drag to select, and the image goes to your clipboard ready to paste.

For folder icons, the same process works. Right-click the folder, Get Info, click the icon, and paste your image. This is useful for organizing folders by color or theme.

How to change icons for multiple apps at once

If you want to change several app icons to match a theme, you will need to repeat the Get Info process for each one — there is no batch tool built into macOS. However, you can speed this up by keeping your new icon image copied to the clipboard, then moving quickly through each app's Get Info window and pasting.

Some third-party apps like Folder Colorizer or LUT Robot offer icon themes that change multiple apps at once, but they require installation and may not work on the latest macOS versions. The manual method is more reliable and takes only a few seconds per app.

Reverting to the original icon

To undo a change and restore the original icon, open Get Info for that app again, click the custom icon at the top-left, and press the Delete key. The original icon returns when ready.

If Delete does not work, drag the app from the App Store again to your Applications folder, and when prompted, choose to replace the existing app. This restores the original icon along with the app itself. Your settings and data inside the app are not affected.

Icons that stay changed after macOS updates

When you change an icon through Get Info, the change is stored in the app's metadata on your Mac, not in the app's code. This means your custom icon survives macOS updates, security patches, and even moving the app to a different folder.

The only time you lose a custom icon is if you delete the app entirely and reinstall it fresh from the App Store, or if you use Migration Assistant to move your Mac to a new computer and something goes wrong during the transfer. In normal use, your icon changes are permanent.

Troubleshooting: icon changes that do not work

If you paste an image and nothing happens, the image format may not be supported. Try converting it to PNG in Preview: open the image, go to File > Export, and choose PNG from the Format dropdown. Then try pasting again.

If the icon appears but looks blurry or stretched, the image may be too small. Icons work best at 512 × 512 pixels or larger. You can resize any image in Preview by going to Tools > Adjust Size and entering the new dimensions.

If Get Info will not let you click the icon, the app may be protected by your Mac's security settings. Try moving the app to a different folder first, or restart your Mac and try again. System apps like Finder cannot have their icons changed this way.

Frequently Asked Questions

Can I change the icon of a system app like Mail or Safari?

No. System apps built into macOS are protected and do not allow icon changes through Get Info. You can change icons for third-party apps you read from the App Store or elsewhere, but not for Mail, Safari, Finder, or other built-in tools.

What image size works best for a Mac icon?

Icons look sharpest at 512 × 512 pixels, but any size from 256 × 256 up to 1024 × 1024 will work. The Mac automatically scales the image down to fit the icon space. Smaller images (under 256 pixels) may look blurry when enlarged.

Will my custom icon show up in the Dock and Launchpad?

Yes. Once you change an icon through Get Info, it appears everywhere — Finder, the Dock, Launchpad, Spotlight search results, and anywhere else the app is displayed on your Mac.

Can I use .icns files directly?

Not through Get Info. The .icns format is Apple's native icon format, but Get Info only accepts standard image files like PNG and JPEG. You can convert an .icns file to PNG in Preview by opening it and exporting as PNG, then use that PNG as your icon.

What happens if I change an icon and then update macOS?

Your custom icon stays in place. macOS updates do not overwrite custom icons stored in app metadata. The only exception is if an update replaces the entire app file, which is rare and usually only happens with major version upgrades.
