Image to ICO Converter
Convert any image — PNG, JPG, WebP, GIF or BMP — into a Windows .ico with every size you need packed into one file. It runs entirely in your browser.
What is an ICO file?
An .ico is the Windows icon format. Unlike a PNG or JPG, a single .ico can hold the same picture at several sizes — 16×16 for the taskbar, 32×32 and 48×48 for the desktop, 256×256 for large/high-DPI views. Windows automatically picks the right size for each place it shows your icon. That is why exporting a single-size PNG rarely looks right as an app icon: you actually want a multi-resolution ICO, which is exactly what this tool builds.

Frequently asked questions
What image formats can I convert to ICO?
PNG, JPG/JPEG, WebP, GIF and BMP. For sharp icons a square source (e.g. 256×256 or larger) works best.
Does it make a true multi-size icon?
Yes. Every size you tick is packed into a single .ico file, which is what Windows and browsers expect — not one flat image.
Are my images uploaded?
No. The conversion runs in your browser with the Canvas API; your image never leaves your device.
Is it free?
Completely — unlimited, no sign-up, no watermark.
