How to convert GIF to JXL

  1. Add your GIF GIFs

    Drop GIF 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.

  2. JXL is already chosen

    Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.

  3. Download

    Save the JXL, or download everything as one ZIP if you converted several files.

Why ToAny

  • Private by construction

    The GIF to JXL converter is part of this page and runs inside your browser. Your GIFs are never sent to ToAny or to anyone else.

  • No upload, no queue

    Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.

  • Free, without an account

    No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.

GIF to JXL: what to expect

GIF is limited to 256 colours and produces very large files for anything longer than a few seconds. JPEG XL gives excellent quality for its size. GIF is at home in short looping clips and reactions; JXL is the usual choice for high-quality photo archives.

The defaults suit most files. Under Options you can set the quality and resize the result.

If the GIF is animated, only its first frame is converted and the result is a still picture. The JXL encoder is a WebAssembly module that downloads the first time you convert to JXL and is cached afterwards.

GIF vs JXL

GIF

GIF image

GIF is a 1987 format that survives because it loops silently everywhere. Each frame can use at most 256 colours, so photos and video look grainy and files are far larger than an equivalent MP4.

JXL

JPEG XL image

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

Questions

Are my GIFs uploaded anywhere?

No. The GIF to JXL conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Does converting GIF to JXL reduce quality?

A little: ToAny writes JXL in its lossy mode, so a small amount of detail is traded for a much smaller file. At the default setting the difference is hard to notice. You can raise the quality under Options; there is no lossless setting.

Can I convert several GIF files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert GIF to JXL on Windows, Mac, iPhone or Android?

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 GIF file, press Convert and save the JXL. There is nothing to install.

Is there a file size limit?

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.
