How do I convert a JFIF image to ICO with this tool?

Upload your JFIF file, choose ICO as the output format, select your desired icon size (like 256x256), and click Convert. You can then download the .ico file for use in Windows or web development.

Why should I use ICO instead of keeping JFIF format?

JFIF is a JPEG-based format optimized for photos and does not support transparency or multiple image sizes. ICO files can contain transparent PNG data and multiple resolutions, making them the standard for Windows icons, favicons, and app shortcuts.

What happens to the quality and transparency when converting JFIF to ICO?

The converter decodes the lossy JFIF image and re-encodes it as a lossless PNG inside the ICO container, so no additional quality loss is introduced. However, since JFIF lacks an alpha channel, the ICO will be opaque unless you edit the result to add transparency separately.
