Why convert JPG to ICO?
Icons have to be small and square, so a photo needs resizing to several sizes at once. This produces a single ICO containing all of them, ready to use as a favicon or application icon.

Making an icon from a photo or JPG logo
JPG has no transparency, so an icon made from a JPG will have a solid background — usually white or whatever color surrounds the subject. That's fine for photos and square logos with a colored background; for a logo that should float on any background, start from a transparent PNG or SVG instead.
Localvert creates 16, 32 and 48 pixel versions inside one ICO file, which is what browsers and Windows use.
Crop to a square first
If the JPG isn't square, the icon is stretched to fit, which distorts faces and logos. Crop the image to a square in any photo editor (or your phone's Photos app) so the important part sits in the middle, then convert.
Is it safe?
Yes. This conversion runs entirely inside your browser, and your JPG file is never sent to a server. Metadata such as location is also removed automatically.

Frequently asked questions
Can I make the background transparent?
Not from a JPG — the format doesn't store transparency. Remove the background in an image editor and save as PNG, then use PNG to ICO.
Will JPG compression artifacts show?
At icon sizes the image is shrunk so much that most artifacts disappear. Starting from a large, high-quality JPG gives the cleanest result.
Where do I put the ICO for my website?
Upload it as favicon.ico to the root of your site, or link it in the page head with <link rel="icon" href="/favicon.ico">.
Is it really free?
Yes. Converting JPG to ICO is free with no sign-up and no watermark. The free plan handles several files per batch; an optional premium licence removes ads and raises the limits.
Are my files uploaded anywhere?
No. Your JPG files are read and converted by your browser on your own device. You can confirm it by opening your browser's developer tools and watching the Network tab while you convert: no file upload ever appears.
