PNG to ICO Converter
Processing entirely on your device — large files may take a moment.
Websites still expect a favicon.ico in the site root and Windows apps need ICO resources — converting from PNG takes seconds. If your files are still in PNG format, this page is the shortcut: PNG is a lossless image format that preserves every pixel exactly and supports transparent backgrounds, which makes it the standard for screenshots, logos and graphics containing text or sharp edges.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.
