Compress JPG images into JPEG XL
Looking to compress JPG photos? Convert JPG to JXL and compare the output size. The result is a .jxl file, not a smaller .jpg file. File-size savings vary by image and quality setting.
A few things to know.
What is a JXL file?
JXL is the file extension for JPEG XL, an image format supporting lossy and lossless compression, transparency, and more. This tool creates still JXL images.
Is this JXL converter free?
Yes. Convert images without an account or a subscription. Processing happens on your device.
Will my converted image always be smaller?
No. File size depends on your source image and compression settings. Already compressed images can become larger. Compare the sizes shown after conversion.
Can I open JXL files in any browser?
Support varies between browsers and image applications. Check your destination's JPEG XL support before replacing original files. Keep your originals for compatibility.
Are animation and original metadata preserved?
No. This converter creates still, 8-bit sRGB images and does not preserve camera metadata, HDR, or animation. Lossless mode preserves decoded pixels, not the original JPEG bitstream.
