Frequently Asked Questions
Yes, absolutely. Unlike other online converters that upload your images to remote servers, JXL Converter works 100% client-side. All processing happens locally in your browser, so your files never leave your computer.

Absolutely! Our tool supports batch conversion. You can drag and drop multiple .any files at once, and they will be processed simultaneously.
Since the tool runs entirely locally on your machine, there are no server-side size limits! However, processing extremely large files (e.g. over 50MB) may consume significant browser memory and CPU.
No installation or registration is required. Our converter is a web-based utility that works directly inside any modern web browser like Chrome, Firefox, Safari, and Edge.
JPEG XL decoding and encoding are computationally heavy. The converter uses WebAssembly to run the codec in the browser, which might briefly utilize your CPU.
If your source image has transparency and you convert to ANY (which may not support it or is standard lossy like JPG), the transparent areas will be filled with a solid white background.
Most conversions are completed in a fraction of a second. For large files or formats that rely on heavy WebAssembly decoding (like JXL), it might take a few seconds depending on your device's CPU speed.
Your original files remain completely untouched on your device. The converter only reads the data to generate a new converted version in memory, which you can then download.
