Free PNG to ICO converter online
Need a ICO instead of a PNG? This free converter turns PNG files into ICO images right in your browser. Add as many files as you like, adjust the settings and download the results individually or together as a ZIP.
PNG is a lossless format: it never throws image data away, so text and sharp edges stay crisp and it supports full transparency. The trade-off is file size: a photo saved as PNG is often 5 to 10 times bigger than the same photo as JPG. PNG files can hold hidden text chunks with software names, authors and dates.
ICO is the Windows icon format and the classic format for website favicons. A single .ico file can hold several sizes (16x16, 32x32, 48x48 up to 256x256) so the operating system or browser can pick the sharpest one.
