How to Change Folder Icons on Mac (2026 Step-by-Step Guide)

The default blue folder on macOS gets the job done — but after a few dozen of them, your desktop turns into a sea of identical blue rectangles. Changing folder icons is the fastest way to find things at a glance and make your desktop feel like yours. Here's exactly how to do it.

First: what macOS already does for you

Since macOS 26 Tahoe, Finder has a built-in option. Control-click any folder and choose Customize Folder — you get a row of preset colours, plus a symbol or an emoji to sit on the folder. Applying a Finder tag now tints the folder icon itself rather than just adding a coloured dot next to the name. It carries over to macOS 27 Golden Gate, and it takes about three seconds.

It's genuinely useful, and it's also where the built-in feature stops:

• You get Apple's preset colours — not a palette you chose.
• The mark on the folder is a system symbol or an emoji — not artwork.
• Every Mac running Tahoe or later has exactly the same options, so nothing you make looks like yours.

For an actual designed folder — illustration, texture, a matching set across your whole desktop — you still need to apply your own image. That's the rest of this guide, and it works on every macOS version from Big Sur through Golden Gate. (New to macOS 27? See how folder icons work on macOS 27 Golden Gate.)

The quick method: paste any image

This is the fastest way and works with any picture (PNG, JPG, or an .icns file).

1. Open the image you want to use. In Preview, press Cmd + A to select all, then Cmd + C to copy it.
2. Select the folder you want to change and press Cmd + I to open the Get Info window.
3. Click the small folder icon in the top-left corner of the Get Info window (a thin blue outline appears around it).
4. Press Cmd + V to paste. Done — your folder instantly wears the new icon.

That's it. No third-party apps, no Terminal.

The clean method: use an .icns icon pack

If you downloaded a proper icon pack, you'll have .icns files — these are made for exactly this and look crisp at every size.

1. Select your folder and press Cmd + I (Get Info).
2. Drag the .icns file directly onto the small folder icon in the top-left of the Get Info window.
3. Release. The icon updates immediately.

Because .icns files contain multiple resolutions, the icon stays sharp whether you're viewing it tiny in the sidebar or huge on the desktop.

How to change it back

Made a mistake or want the default blue folder again?

1. Select the folder, press Cmd + I.
2. Click the icon in the top-left of the Get Info window so it's highlighted.
3. Press Delete. The original folder icon comes right back.

Tips for a tidy desktop

• Use a consistent set. A matching icon pack (same style, same palette) looks far more intentional than random icons from different sources.
• Colour-code by purpose. Pink for personal, blue for work, green for finances — your eyes find folders before you even read the labels.
• Keep the icon files somewhere safe. If you ever reinstall macOS or get a new Mac, you'll want them again.

Where to get folder icons that actually look good

Free icons scattered across the web are often low-resolution or wildly mismatched. If you want a desktop that looks designed rather than thrown together, start with a curated, matching set.

FolderIcons offers original, hand-crafted folder icon skins made as complete sets — animals, minimal, gaming, seasonal and more. Every download includes the .icns files for Mac plus a step-by-step install guide, so the steps above take seconds. Browse the gallery (three skins are free for every member), unlock the sets you love, and own them forever.

Your folders, your style.
