Files
These sample files are generated on the page. Convert them to try it out, or add your own.
Click “Choose JPG files” or drop them on the page. You can add several at once.
ICO is already selected. The file will hold icon sizes from 16 to 48 px, and up to 256 px if the source image is large enough.
Click “Convert”, then download your ICO file. With several files, grab everything at once as a ZIP.
A JPG has no transparency, so the icon keeps its original background, often white, which shows up as an obvious square in a dark-mode tab or on a dark desktop. Before converting, also crop the image to a square, tight around the subject: with a rectangular image, the bands added on either side make the icon look smaller.
For a logo, start from its PNG or SVG version if you can, as it is often transparent and sharper than the JPG. Otherwise, cut out the JPG in an editing app, save it as PNG, then convert that PNG to ICO. The resulting file works as a favicon as well as an icon for a shortcut or a folder in Windows.
The most widely used photo format, introduced in 1992. Its lossy compression keeps files small, and it opens everywhere: phones, computers and social networks. It does not support transparency.
The Windows icon format. One file holds several sizes, from 16 to 256 pixels; it is the classic format for website favicons.
Rarely as it is. In a tab a favicon is shown at 16 or 32 px: a face or a single object, cropped very tightly, stays recognisable, but a landscape, a group photo or text does not. Simplify the image, boost the contrast and check how it looks at a small size before publishing.
The ICO format is square: for a round look, everything outside the circle must be transparent, which JPG cannot do. Crop the photo into a circle in an editing app, save it as a PNG with a transparent background, then convert that PNG to ICO: the transparency will be kept.
No. The file is read and converted by your browser, on your device. Nothing is sent to a server, and nothing is kept after you close the page.
The image is resized to the standard icon sizes (16, 24, 32 and 48 px, plus 64, 128 and 256 px when it is large enough), then saved losslessly. Start from an image of at least 256 px for a crisp icon.
As many as you like, for free and without signing up. Add them all, then download the results one by one or in a single ZIP. The maximum size depends on your device and browser, with a few caps that protect its memory (for example 20,000 files per archive or 5 million filled cells per workbook: see the home page FAQ); a file over one of them is not converted, and a message says so.
Formatomat is designed for recent browsers on computers, iPhone and Android, with no app to install. A conversion the browser cannot do (a format it cannot read or write) is refused with a message that says so.
