Why Convert JPG to ICO?

An ICO file is what Windows and web browsers reach for when they need a small square icon: a favicon in the address bar, an app shortcut, a desktop launcher. A JPG photo isn't one.

Pack it into the .ico container and you get a file the operating system and your site's icon tag actually accept, favicon and all, which a bare .jpg never manages on its own.

Frequently Asked Questions

What size should the JPG be first?
Icons are tiny and square, so crop the JPG to a square and resize it to 256 pixels or smaller before converting. A large rectangular photo makes a blurry, oddly shaped icon.
Can ICO show the JPG's detail?
Only a little. At favicon sizes like 16 or 32 pixels, fine detail disappears no matter the source. Simple, high-contrast artwork reads far better as an icon than a busy photo.
Does ICO support transparency?
The ICO format does, but a JPG source has no transparency to carry over. Start from a PNG if you need a transparent icon background.
Where do I use the resulting .ico?
Drop it at your site root as favicon.ico, or point a <link rel="icon"> at it. On Windows it also works as a shortcut or application icon.
Is this conversion free, and is my file private?
Yes. The conversion runs in your browser tab, nothing is uploaded, and no account is needed. The only limit is size: 25 MB for this format. Bigger files route to the desktop app.
