Convert images to JPEG XL
Turn almost any image – JPG, PNG, HEIC, RAW, PSD, TIFF, SVG and more – into small, sharp .jxl files. Everything happens in your browser; your images are never uploaded.
Best for photos. 85–90 is usually impossible to tell from the original.
Higher makes smaller files but takes longer.
Converted on your device with libjxl (WebAssembly). Nothing is sent or stored.
How it works
Add your images
Drag them into the box, tap “Choose images” or paste a screenshot with Ctrl+V. You can add many images at once.
Pick a setting
“Smaller file” suits photos. “Lossless” keeps every pixel and suits screenshots, logos and graphics. Higher effort makes slightly smaller files but takes longer.
Download
Each image gets a download button showing the new size. Changed the settings? Tap “Apply new settings” to convert again.

About JPEG XL
What is JPEG XL?
JPEG XL (.jxl) is a modern image format that makes smaller files than JPG and PNG at the same quality. It supports lossless and lossy compression, transparency, wide colour and high bit depth.
Lossless or smaller file?
Lossless gives an image identical to the original and suits screenshots, logos and graphics – often much smaller than PNG. "Smaller file" (lossy) makes far smaller files and suits photos.
Can it convert animated GIFs?
Yes. Animated GIF, APNG and animated WebP become animated JPEG XL with the same frame timing and looping. Not every program plays animated JPEG XL yet – some only show the first frame.
Why did my JPG get bigger?
A JPG is already compressed. Converting it losslessly stores every pixel exactly, which takes more space. Use "Smaller file" for JPG photos.
Are my images uploaded?
No. The converter runs in your browser with WebAssembly. Your images never leave your device.
Is there a size limit?
No fixed limit, but very large images (above about 50 megapixels) can be slow or fail on phones and older computers, because everything happens in your browser.
Which programs can open .jxl files?
Safari, recent versions of Windows and macOS, and apps like GIMP, Photoshop, Affinity and IrfanView can open JPEG XL. Not every browser shows .jxl yet, so keep a JPG or WebP version for websites.
