Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To convert PNG to ICO, upload one PNG, choose how it should be framed inside the square icon canvas, pick a transparent or solid background, and export. The converter generates a single .ico file containing the standard embedded sizes, all without sending the image to a server.
A square source PNG produces the cleanest icon, but you can use fit framing to keep the whole image visible with padding, or fill framing to crop it edge to edge. Transparency is preserved when the source artwork and chosen background allow it, which keeps favicons crisp against any page color.
An .ico file is the classic Windows and web icon format, most commonly used as a site favicon (favicon.ico) and for desktop application and shortcut icons. Because a single .ico can embed several resolutions, browsers and the operating system pick the size they need from one file.
This page keeps the job focused on turning one PNG into one ICO, rather than burying it inside a larger favicon bundle generator. That makes it the fast path when all you need is a clean .ico for your site or app.
Short answers for the questions people usually have before trying a utility like this.
Yes. This is a free PNG to ICO converter that runs in your browser with no signup and no watermark.
Yes. The export includes the standard embedded icon sizes inside one .ico file for broader compatibility across browsers and Windows.
Yes. Transparent background is supported when the source artwork and the chosen background allow it, so favicons stay crisp on any color.
No. The conversion runs locally in your browser, so your PNG never leaves your device.
A square PNG of at least 256 by 256 pixels works best, since the converter can scale it down cleanly to every embedded icon size.
