Why convert PNG to ICO?
PNG files are best for screenshots, logos and graphics with sharp edges or transparency. ICO is the better choice for website favicons and Windows app icons. It opens in browsers and Windows, while PNG opens in every browser, phone and image editor.
ICO is lossless, so nothing your PNG file contains is thrown away on the way.

What happens to your file
Your browser decodes the picture with its own built-in image decoder, draws it onto an invisible canvas at full resolution, and re-encodes the pixels in the new format. This is the same code your browser uses to show images on every web page, so it is fast, and the pixels never leave the tab.
Tips for a clean conversion
- Drop a whole folder's worth of PNG files at once. They convert one after another and you can download everything as a single ZIP.
- Keep your original PNG files until you have checked the results. Converting back later is rarely lossless.
- ICO keeps everything it receives, so the result is only ever as good as the PNG file you start with.
