Drop WebP 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 JXL, or download everything as one ZIP if you converted several files.
The WebP to JXL 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.
WebP is still rejected by plenty of desktop apps, older software and upload forms. JPEG XL gives excellent quality for its size. WebP is at home in images on websites; 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 WebP 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.
WebP is Google's image format for the web. It is typically a quarter to a third smaller than JPG or PNG at similar quality and supports both transparency and animation. Browsers handle it well; older editors, printers' portals and some messaging apps do not.

WebP converterJPEG 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

No. The WebP to JXL conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
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.
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 WebP file, press Convert and save the JXL. 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.
