What is a JPG to ICO converter?

A JPG to ICO converter takes a JPEG photograph or illustration and turns it into a Windows icon file. ICO is a special container format that holds several images at different sizes inside a single file — most commonly 16×16, 32×32, 48×48 and 256×256 pixels. Windows, browsers and applications pick the best size for the context: a tiny 16 px icon for a taskbar, a 32 px icon for a desktop shortcut, a 256 px icon for File Explorer's large-thumbnail view. Using a single ICO gives you crisp icons everywhere without maintaining separate files.

This tool runs entirely inside your browser using JavaScript and the HTML canvas API. Your JPG files stay on your device and are never uploaded to a server, so you can convert private logos, personal photos or confidential artwork without any third party ever seeing them.

Frequently Asked Questions

Add your JPG files to the drop zone, tick the icon sizes you want, then click Convert to ICO. Each JPG is resized to every selected size and packaged into a single multi-size ICO file you can download immediately.

ICO is a container image format that holds multiple images at different sizes in a single file. It's primarily used for Windows application icons and website favicons, where a single ICO provides crisp icons for every display context.

For favicons, 16, 32 and 48 px cover most browsers and tabs. Adding 64, 128 and 256 px gives you higher-resolution versions for bookmarks, desktop shortcuts and retina displays. A good default is 16, 32, 48 and 256.

JPG does not support transparency, so the ICO will have a solid background (usually white or whatever the JPG shows). If you need a transparent icon, start from a PNG source instead.

No. The conversion happens entirely inside your browser using JavaScript and the HTML canvas API. Your JPG files never leave your device.
