Drop JXL (JPEG XL) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.
Save the ICO, or download everything as one ZIP if you converted several files.
The JXL to ICO converter is part of this page and runs inside your browser. Your images are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
JPEG XL does not open in most browsers or apps yet. ICO holds several sizes in one file, which is what favicons and Windows shortcuts need. JXL is at home in high-quality photo archives; ICO is the usual choice for website favicons and Windows app icons.
ICO holds a single still image, so an animated JXL does not stay animated. The defaults suit most files. Under Options you can pick which icon sizes go into the file.
JPEG XL is the JPEG committee's modern successor to JPG, standardised in 2022. It compresses better than JPG at the same quality and can also store images losslessly. Software support is still limited.
Opens in Safari 17 or later and a handful of image apps; most other browsers do not display it by default
JXL converterAn ICO file bundles the same icon at several sizes, such as 16, 32 and 48 pixels, so Windows or a browser can pick the sharpest one. It is still the most compatible way to ship a favicon.
Opens in Windows and every browser (as favicon.ico)

No. The JXL to ICO conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
The picture is scaled down: an icon file holds small square copies of it (16, 32, 48 and 256 pixels by default), so anything larger loses detail and a picture that is not square gets empty space around it. Each size is stored without further loss. You can pick the sizes under Options.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the JXL file, press Convert and save the ICO. There is nothing to install.
Pictures of up to 120 megapixels are accepted (for example 12,000 by 10,000 pixels); a larger one is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
