Frequently asked questions
Will my PNG lose quality when converted to ICO?+
No — we embed your PNG directly inside the ICO container, preserving the original pixels and transparency.
Can I convert transparent PNG images to ICO?+
Yes. The ICO format fully supports the PNG alpha channel, so transparency carries over to the output.
Can ICO files contain multiple sizes?+
Yes. A single ICO can store many resolutions (e.g. 16, 32, 48, 256). Windows and browsers pick the best size automatically.
Can I use the ICO file as a favicon?+
Absolutely. Save it as favicon.ico in your site root, or reference it via a <link rel='icon' href='/favicon.ico'> tag.
Is this tool free?+
Yes, completely free with no watermarks, no signup, and no upload to our servers — everything runs in your browser.

Learn more about PNG to ICO Converter
PNG to ICO conversion is the fastest path from a flat logo file to a Windows-ready icon or browser favicon. Our converter embeds your PNG pixels inside a multi-resolution ICO container so 16×16 through 256×256 sizes stay sharp in the taskbar, Start menu, and browser chrome. Because processing runs entirely in your browser, transparent PNGs keep their alpha channel and nothing uploads to a remote server. Use this tool when you already have a square PNG and need favicon.ico, a desktop shortcut icon, or legacy ICO assets for installers and Electron apps.
