Windows icon recolor tool.

Find the ICO (right-click the shortcut, Properties, Change Icon shows the path), drop it here, change the color, download the PNG, pack it as ICO and set it as the shortcut's icon.

Yes. Drop a folder ICO, change the yellow to your color, pack it and apply it through the folder's Properties, Customize, Change Icon.

In C:\Windows\System32\shell32.dll and imageres.dll; an icon extractor pulls ICO files out of them. Third-party icon packs are easier.

Use the same new hex for every icon and keep the setting noted; the desktop ends up one color family.

You can recolor the icon; putting it back into an .exe needs a resource editor such as Resource Hacker. The icon is made here, the embedding elsewhere.

Turn on preserve shades: the gradient and shadows keep their lightness while the hue changes, so the Windows 11 look stays.

Drop the ICO, pick the color to change (click it in the preview or type its hex) and the color to change it to. Tolerance widens the match to nearby shades, which anti-aliased icon edges need: 10 to 20 is a good start.

Turn on preserve shades. The tool then keeps each pixel's lightness and swaps only its hue and saturation, so a folder keeps its shading and a gradient icon its depth.

The largest frame of the ICO is edited and the result is a PNG, which every editor opens and modern browsers accept as a favicon. For a classic favicon.ico, pack the PNG with the PNG to ICO tool.

No. The ICO is read and its frames decoded by JavaScript on your device; the page makes no request with your file. Load it, go offline and it still works.

No. The Windows icon recolor tool is free and opens without a sign-in, an account or an install.

Up to 100 MB per file, the limit the tool states under its drop area. A larger file is refused with a plain message instead of being decoded.

No, it takes one file at a time. If you drop or choose several, only the first is used; run the tool again for the next one.

The edit is written as a PNG because PNG stores every pixel exactly, with a full alpha channel, so the result can be edited again without a second round of loss.

No. The browser decodes the image and the tool writes a new file from its pixels, so camera EXIF, GPS position and text chunks in the original are not copied into the result. Keep the original file if you need them.

No. The result has the same width and height in pixels as the source.
