Images to ICO Converter
Image to ICO converter is a useful tool that allows you to convert images to ICO format
ICO is what your browser tab's tiny icon actually is, technically. Same format Windows uses for desktop app icons. The clever bit: a single ICO file can hold several sizes of the same image bundled together, 16x16, 32x32, 48x48, so whatever's displaying it grabs the size it needs instead of stretching one image awkwardly.
If you've ever tried uploading a plain PNG as a favicon somewhere and gotten a rejection error, this is why. Most upload fields want a real ICO file, not an image with the extension renamed (that trick doesn't actually work, the file format itself has to match).
Upload your logo, and we'll build a proper multi-size ICO file out of it, ready to drop into your site's root folder or app icon settings.
