What is JPEG?
JPEG is an image compression standard developed by the Joint Photographic Experts Group. Files commonly use either the .jpeg or .jpg extension. JPEG is widely used for photographs and normally uses lossy compression.
JPG and JPEG refer to the same image format. This converter decodes the image and encodes its pixels as JXL; it does not preserve the original JPEG bitstream.
What is JXL?
JXL is the file extension for JPEG XL, an image format designed for efficient image compression. JPEG XL supports lossy and lossless compression as well as transparency, making it suitable for both photographs and graphics.
This JPEG to JXL converter creates still, 8-bit sRGB images. Choose high quality to balance detail and file size, or lossless to preserve the decoded pixels. File-size savings are not guaranteed, and JPEG XL support varies between browsers and image applications. Keep your original JPEG files for compatibility.
