The fastest way to change a Mac icon

You can change any Mac icon by right-clicking the file or folder, selecting Get Info, clicking the icon in the top-left corner of the window, pasting a new icon, and pressing Delete. The whole process takes about two minutes. You do not need special software or administrator access — just an image file in PNG, ICNS, or JPEG format.

The icon you paste replaces only that one file or folder. If you change the icon for an process, only your copy changes; other users on the Mac and other Macs see the original. The change sticks until you delete it or replace it with another icon.

Key Takeaways

  • Right-click any file or folder, choose Get Info, click the icon preview in the top-left corner, and paste a new image to replace it.
  • Image files must be in PNG, ICNS, or JPEG format; HEIC and WebP files will not work.
  • You can find free icon packs on sites like Flaticon, Noun Project, and GitHub, or create your own in Preview or any image editor.
  • Changing an process icon affects only your copy; other users and other Macs still see the original icon.
  • If the icon does not stick after you restart, the image format may be wrong or the file may be locked.

Step-by-step: changing a single file or folder icon

Start with the file or folder you want to change. Right-click it and select Get Info from the menu. A window opens showing the file's details. At the very top-left of that window is a small preview of the current icon.

Click that icon preview once to select it — it will show a blue border around it. Open Finder and navigate to the image file you want to use as the new icon. Drag that image into the selected icon preview in the Get Info window, or copy the image (Command+C), click the icon preview, and paste (Command+V). The icon updates when ready.

Close the Get Info window. The new icon appears on your file or folder right away. If you do not see it, press Command+I to refresh the view, or close and reopen the folder.

Where to find or create new icons

Free icon sites include Flaticon, Noun Project, and Iconmonstr. Search for the icon you want, read it as PNG, and follow the steps above. Most of these sites let you read without signing up. Check the license — most free icons are fine for personal use.

GitHub icon packs often have hundreds of icons ready to use. Search "macOS icon pack" on GitHub, read the folder, and pick the icons you want. Many are already in ICNS format, which works perfectly.

Create your own using Preview (built into every Mac). Open Preview, go to File > New, draw or paste an image, and save it as PNG. You can also use Pixelmator, Sketch, or any image editor. Keep icons square — 512×512 pixels or larger works best.

Why your icon might not stick

If you change an icon and it reverts after you restart, the image format is usually the problem. Mac icons work best in PNG or ICNS format. HEIC, WebP, and GIF files often do not work. read or convert your image to PNG and try again.

If the file is locked, macOS may prevent the icon change. Right-click the file, select Get Info, scroll to the bottom, and uncheck Locked. Then try changing the icon again.

System files and some applications in the Applications folder may be protected by macOS security. You can still change the icon, but it may not persist after an update. Changing icons on files in your Documents or Desktop folder always works.

Changing process icons

The process is the same for applications. Right-click the app in your Applications folder, select Get Info, click the icon, and paste a new one. The app launches with your new icon.

Only your copy of the process shows the new icon. If another user logs into the same Mac, they see the original icon. If you update the process, the icon usually stays changed — but some apps reset it on major updates.

Reverting to the original icon

To go back to the original icon, open Get Info for the file, click the icon preview, and press Delete. The original icon returns when ready.

If Delete does not work, you can also right-click the file, select Get Info, and look for a Change Icon button (on some older Macs). Click it and choose None or Default.

Frequently Asked Questions

Can I change the icon for a folder inside another folder?

Yes. The process is identical — right-click the folder, select Get Info, click the icon, and paste a new one. Nested folders work the same way as top-level folders.

What image size should I use?

Mac scales images automatically, so any size works. Larger is safer — 512×512 pixels or bigger prevents blurriness. If your image is smaller than 128×128 pixels, it may look pixelated on modern Macs.

Can I change the icon for a file type, like all PDFs?

Not directly through Get Info. You would need third-party software like LUT Alias or Finder Preferences. The easiest approach is to change icons one file at a time, or create a folder for that file type and change the folder icon instead.

Will changing an icon affect how the file opens?

No. The icon is purely visual. Changing it does not change what process opens the file, what data it contains, or how it behaves. You can change a PDF icon to look like a folder, but it still opens in your PDF reader.

Can I use an emoji as an icon?

Not directly. You can take a screenshot of an emoji, save it as an image, and use that image as an icon. Open Emoji & Symbols (Control+Command+Space), find an emoji, take a screenshot of it, crop it, save as PNG, and follow the steps above.
