About this tool
ICO files hold several sizes of an icon, and most editors and websites cannot open them. This converter extracts the largest, sharpest image inside and saves it as a lossless PNG with transparency intact, ready for editing or for use anywhere a normal image is expected.
About the formats: ICO is the Windows icon container: one file holding the same picture at several sizes (16, 32, 48, 256 pixels and so on) so the system can pick the right one. It is still what browsers look for as favicon.ico and what Windows uses for program and folder icons. PNG (Portable Network Graphics) is a lossless image format with full transparency support. It is the standard choice for screenshots, logos, icons, and anything with sharp edges or text, but it produces much larger files than JPG or WebP for photographs.
How to use it
- Drop your ICO files into the box above, or click to browse. Nothing is uploaded.
- Click Convert to PNG and wait a moment.
- Download the results individually or all at once as a ZIP.
Questions
Which size is extracted from the ICO?
The largest image in the file, which is normally the 256 pixel version. Use the resize tools afterwards if you need a specific smaller size.
Is transparency kept?
Yes. Transparent icon backgrounds stay transparent in the PNG.
Is it free, are files uploaded, which browsers work: the general questions are answered once for the whole site.
