ICO to PNG converter
Open any .ico file and see every image packed inside it. Save the size you need as a PNG with transparency, or take them all.
What you’ll find inside an .ico
Most favicon.ico files hold 16, 32 and 48 px images; Windows application icons usually add 24, 64, 128 and 256. Older icons may carry the same size several times at different colour depths (4-bit, 8-bit and 32-bit), from the days when displays could only show 16 or 256 colours. This tool shows each one separately so you can pick the best.
If you want to rebuild the icon from the largest PNG, drop it into the PNG to ICO converter, or into the favicon generator for a full modern package.
Questions people ask
How do I convert ICO to PNG?
Drop the .ico file on this page. Every image stored inside it is listed with its size and colour depth; save any one as a PNG, or download them all in a zip.
Why are there several images in one .ico?
An .ico is a container. Windows and browsers pick the stored size closest to what they need, so icon makers include 16, 32, 48 and often 256 px versions.
Does it work with old icons from Windows XP and earlier?
Yes. Besides PNG-compressed icons, the converter decodes classic bitmap icons in 1, 4, 8, 24 and 32-bit colour, including the transparency mask.
Is the file uploaded?
No. The .ico is parsed byte by byte in your browser with JavaScript.
