About ICO and PNG

ICO is designed for icons. Multi-resolution icons are packed into a single file.

PNG output is lossless and keeps the alpha channel intact.

ICO files are read by the convertexa engine that ships with this page, so the conversion is identical whether you use this tool or the general converter. The output is produced with the same codec settings for every visitor, which means the same input always produces the same result.

Limitations

  • Only the largest icon inside the .ico file is converted.

Frequently asked questions

How do I convert a ICO file to PNG?

Add your ICO file to the box above. convertexa detects the format from the file content, applies the ICO to PNG conversion and gives you the result to download. The whole operation runs inside your browser.

Are my ICO files uploaded anywhere?

No. The conversion runs in a sandboxed worker on your own device. Your file never leaves the browser, and nothing is stored on a server.

Is the ICO to PNG conversion lossless?

Yes. This conversion preserves all of the source data, so the PNG file is equivalent to the original ICO file.

Is there a size limit?

For reliable results keep the input under 40 MB. Very large files run out of memory in the browser rather than failing quietly.

Which browsers are supported?

Any current version of Chrome, Edge, Firefox or Safari on a desktop. The conversion engines need WebAssembly and Web Workers, both of which are standard since 2018.
