Why use a JPG to ICO converter
A JPG to ICO converter lets you create a Windows icon or website favicon from any image instantly. ICO is the standard icon format used by Windows for application icons, desktop shortcuts, and taskbar icons, and it is also the traditional format for website favicons — the small icon that appears in browser tabs, bookmarks, and browser history.
Creating an ICO file from your logo or image used to require specialist software like Photoshop with specific plugins. This free JPG to ICO converter makes the process instant — upload any image and download a properly formatted ICO file at any standard icon size in seconds.

The traditional favicon format is ICO, and most web servers and CMS platforms including WordPress expect a favicon.ico file. Using a JPG to ICO converter lets you turn your logo or brand image into a properly formatted favicon instantly.
Creating Windows application icons — Windows applications use ICO files for their icons — the image that appears on the desktop shortcut, in the taskbar, and in Windows Explorer. Developers creating Windows applications use a JPG to ICO converter to turn their app logo into the required ICO format.
Creating desktop shortcut icons — Windows allows you to customise the icons used for desktop shortcuts and folders. Using a JPG to ICO converter lets you create a custom icon from any image for use as a personalised desktop shortcut icon.

How to use this JPG to ICO converter — step by step
Upload your JPG or PNG image by clicking the upload button above. For the best result, use a square image with your logo or subject centred — ICO files are always square, so non-square images will be cropped or scaled to fit. Select your preferred ICO size from the dropdown — 32×32 for standard favicons, 16×16 for small browser tab icons, or larger sizes for application and desktop icons.
Click Convert to ICO. Your browser resizes the image to the selected dimensions and creates an ICO file. Download your ICO file and use it as your website favicon, Windows icon, or application icon.
Frequently asked questions about JPG to ICO conversion
What size should I use for a website favicon?
For a standard website favicon, 32×32 pixels is the most widely compatible size. For the very small browser tab icon, 16×16 pixels is used. Many modern websites provide multiple sizes — start with 32×32 for the best balance of quality and compatibility.
Can I use a PNG image instead of JPG?
Yes. This converter accepts both JPG and PNG images. PNG images with transparent backgrounds work especially well for ICO files since the transparency is preserved in the output.
Is my image safe when using this JPG to ICO converter?
Yes. Your image is converted entirely inside your browser. Nothing is uploaded to any server at any point.
How do I add the ICO file as my WordPress favicon?
In WordPress, go to Appearance → Customize → Site Identity → Site Icon and upload your ICO file or a PNG image. WordPress will handle the favicon automatically from there.
How is this JPG to ICO converter different from others?
Most online JPG to ICO converters upload your image to their servers. This converter runs entirely in your browser — no account needed, no upload, and completely free.
