WebP to JXL: What Is JXL and Should You Use It?
People search for “WebP to JXL” because they heard JXL is the next format after WebP. This guide explains what JXL really is, why converting to JXL today is usually a mistake, and what to use instead.
What is JXL?
JXL stands for JPEG XL. It is a newer image format designed to replace JPG. It can store photos at high quality in smaller files than JPG, and it supports transparency like PNG. On paper, it is better than both JPG and WebP.
The problem is support. Most phones, photo editors, chat apps and upload forms cannot open JXL files yet. A file that no one can open is not useful, no matter how good its compression is. That is why PixelTools does not offer a WebP to JXL converter yet — it would make your files harder to use, not easier.
What to use instead of JXL today
- JPG — for photos you need to share, upload or print. Opens almost everywhere.
- PNG — for transparency, logos, screenshots and lossless quality. Files are larger for photos.
- WebP — for the smallest file on a website that supports it. Good for web, bad for forms that only accept JPG/PNG.
- JXL — wait until your apps and forms support it. Do not convert important photos to a format you cannot open.
If you ended up with a WebP file that will not open or upload, the fix today is not JXL — it is JPG. Convert WebP to JPG with the tool below, and your file will work in almost every app and form.

JXL is a newer image format designed to replace JPG. It can compress better than JPG and WebP and supports transparency and high quality. It is promising, but most phones, editors and forms do not support it yet.

Not yet. Because most apps cannot open JXL files, converting to JXL would make your file harder to use. For compatibility today, convert WebP to JPG or WebP to PNG instead.
