JPG to ICO Converter (Free Online)

Turn JPEG images into ICO icon files in your browser. Create favicons and Windows icons from JPG; choose layer sizes and download instantly. No server upload.

JPEG (JPG) photos work fine as a starting point. Because JPG does not support transparency, your ICO layers will have no alpha channel unless you switch to PNG or WebP for transparent icons.

How to convert JPG to ICO

Select your .jpg / .jpeg file in the tool above.
Pick sizes — use Recommended for typical favicon + Windows use, or toggle individual sizes (e.g. 48 and 32 for Explorer views).
Download the .ico file. Processing stays on your device.

When to prefer PNG or WebP instead

You need a transparent background → use PNG to ICO or WebP to ICO.
You have a logo with flat colors → SVG often scales best; see SVG to ICO.

FAQ — JPG to ICO

Why does my icon have a white or solid background?

JPEG compression does not store transparency. If you need a transparent icon, export your artwork as PNG or WebP first, then convert.

Can I use the ICO as a Windows app icon?

Yes. The downloaded ICO follows the common multi-resolution format Windows expects for shortcuts and executables (when you assign icons in properties).

Is there a file size limit?

Large JPEGs are accepted up to 5 MB per file in this tool. Very large photos may be overkill — consider resizing in an editor first for faster loading.
