How To Add an Icon to a File: Personalizing Your Files

Adding a custom icon to your files is an easy way to personalize your computer and make your files more recognizable. Whether you want to assign icons that match the file type or simply use an image you like, customizing icons can help you identify files quicker and make your system more aesthetically pleasing.

This guide will walk you through everything you need to know to change file and folder icons on Windows, Mac, and Linux operating systems.

Finding and Preparing Custom Icons

The first step is to find or create an image you want to use for the new icon.

Icon Requirements:

  • Square dimensions (equal width and height). Many icons are already square, but you may need to crop other images.
  • Simple design with a transparent background. Complex backgrounds don’t render well at small sizes.
  • Saved as an ICO (Windows), ICNS (Mac), or PNG (Linux) file.

Here are some ways to find icons:

  • Icon websites – Many free icon sites like IconArchive and IconFinder have libraries of icons to browse and download.
  • Convert images – Convert your own images like photos or logo files to icon files using free online converters like ICO Convert or FileZigZag.
  • Extract app icons – Extract an icon from another app or system file using a free utility like Greenfish Icon Editor.

Once you’ve found or made an icon file, it’s ready to assign to files.

Changing Icons in Windows 10/11

To customize a file or folder icon on Windows:

  1. Right-click the file/folder and select Properties.
  2. Click the Customize tab > Change Icon.
  3. Click the new icon file > OK.

To reset back to the default system icon, repeat steps 1-2 and click Restore Default.

To make your icon apply to all files of that type:

  1. Right-click an example file > Properties.

This will now set any file with this extension to show the custom icon by default.

To customize a file or folder icon on Mac:

  4. Go back to the file info window and click the icon, then Paste.

The selected image will replace the previous icon.

Changing Icons on Linux

Most Linux desktop environments like GNOME don’t show desktop icons by default. To enable this:

  1. Search for “Desktop Icons” extension and install.
  2. Restart the desktop or log out and in again. A desktop folder should now be available to store files.

To customize file and folder icons once desktop icons are enabled:

  1. Right-click on the file/folder > Properties.
  2. On the Image tab, click the folder icon.
  3. Select the new icon file > Open.

The icon will now reflect the selected image.

Icon Design Tips

  • Stick to simple shapes and silhouettes for maximum clarity at small sizes.
  • Use distinct colors and imagery so icons are easy to visually distinguish.
  • Make icons represent the file or program function when possible.
  • Create an icon set or theme for a cohesive look across your system.

Troubleshooting Issues

If your custom icons revert back to generic images, try these tips:

  • Confirm the icon file is still located in its original folder. If Windows/Mac can’t find it, it will revert.
  • Check the icon file meet size and format requirements for the OS.
  • Try reassigning the icon using the steps for your OS.
  • Restart your computer to refresh the icon cache.

Be careful when changing system file and folder icons. It’s best to only modify copies or personal files and folders to prevent issues.
