PNG to ICO is a free browser-based converter that transforms PNG images into ICO format entirely in your browser. The conversion happens entirely in your browser using the Canvas API — no file ever reaches a server. This is useful when a platform requires a specific format, when you need to reduce file size by switching to a more efficient format, or when you need to add or remove transparency support. The output is available for download immediately after processing.
