About the Image to ICO Converter
The Img Stop Image to ICO Converter turns ordinary pictures into .ico icon files. It opens JPG, PNG, WebP, SVG, AVIF, GIF and BMP images and saves them either at one size (16, 32, 48, 64, 128 or 256 px) or as one multi-size .ico that holds 16, 32, 48 and 256 px together. Images that are not square are centred on a transparent square, so nothing is stretched or cut off.
A multi-size .ico is the best choice for website favicons and Windows icons, because the browser or Windows picks the size that fits each place. Everything is done in your browser: your images are not uploaded, there is no sign-up and no watermark, and you can convert many files at once.

- Start with a square image of at least 256 × 256 px for the sharpest result.

Frequently asked questions
How do I convert an image to ICO for free?
Add the image to the Img Stop Image to ICO Converter, choose a size or the multi-size option and click Convert. The .ico file is made in your browser and you download it straight away – no sign-up or watermark.
Which ICO size should I choose?
For a favicon or a Windows icon, choose the multi-size .ico. It holds 16, 32, 48 and 256 px, and the browser or Windows uses the size that fits. Pick a single size only when a program asks for one exact size.
What happens to an image that is not square?
Icons are square, so the image is scaled to fit and centred on a transparent square. Nothing is stretched or cropped; the empty sides simply stay transparent.
Can I convert several images to ICO at once?
Yes. Add as many images as you like, even in different formats. All of them are converted with the same size setting and you can download them together as a ZIP.
Are my images uploaded?
No. The conversion runs in your browser and your images never leave your device.
