Try reducing the file towards a 20KB limit in your browser. Reaching the target is not guaranteed; check the saved file size and output quality. The browser decodes one icon image for canvas processing. The output does not preserve a multi-size ICO directory. Check the extension before using it as a Windows icon or favicon. A 20 KB budget is most useful for small, tightly cropped graphics. Simplify the source before sacrificing text readability. If the form rejects this result, check both its exact byte limit and the required extension.
