PNG is a lossless format that supports transparency. This free PNG-to-ICO converter changes your PNG images into ICO entirely in your browser, so your files are never uploaded to any server.

Frequently Asked Questions
How do I convert PNG to ICO?
Drag your PNG file (or several) onto the box, or click to choose them. Each file is converted to ICO instantly, then you click Download to save it. It's free with no signup.
Are my files uploaded to a server?
No. The conversion runs entirely in your browser using your device's own processing, so your images never leave your computer or phone. That makes it safe for private or sensitive pictures.
Can I convert multiple PNG files at once?
Yes. Drop as many PNG files as you like and each one is converted and listed with its own download button, so batch conversion is quick.
What sizes does the ICO include?
The generated .ico packs several standard sizes (16, 32, 48, 64, 128 and 256 pixels) into one file, so it works as a website favicon and as a Windows application icon.
Why convert a PNG to ICO instead of just using the PNG?
A browser's classic favicon.ico and a Windows .exe or shortcut icon both expect the .ico format, not a loose PNG. ICO is a container that holds the icon at several pixel sizes in one file, so the system can pick the right size for a tab, taskbar or desktop. Converting your PNG to ICO gives you that drop-in icon. For a full set with manifest sizes, pair this with the Favicon Generator.
Does the PNG's transparency survive the conversion to ICO?
Yes. ICO supports a full alpha channel, so the transparent background from your PNG is preserved and your icon shows with clean edges instead of a white box. The image stays the same lossless pixels; only the wrapper changes from PNG to the multi-size ICO container. Start from a square PNG so the smaller 16 and 32px versions stay sharp and centered.
