Which image formats can I convert to ICO?

You can convert JPG, PNG, BMP, WEBP, and GIF images into the ICO icon format. Each input file becomes a standalone .ico file.

Does the converter keep transparency?

Yes. When you convert from formats that support an alpha channel, such as PNG or WEBP, the transparent background is preserved in the resulting ICO file.

What size should my icon be?

Leave the width and height blank to keep the source size, or set a custom value. Common Windows icon sizes are 16x16, 32x32, 48x48, and 256x256 pixels; choose the size that matches where the icon will be used.

Can I convert several images at once?

Yes. Upload multiple images, click Convert All, and then use Download All to receive every converted icon together in a single ZIP archive.
