Complete Guide: LAB to XYZ Converter
Everything you need to know about using this tool effectively
The LAB to XYZ Converter transforms CIELAB (L*a*b*) color values to CIE XYZ using the standard conversion formulas and D65 reference white point. CIE XYZ is an intermediate color space used in conversions between LAB and RGB. The tool accepts L*, a*, b* inputs and produces X, Y, Z values. All processing happens in the browser.
This tool implements the LAB-to-XYZ conversion formulas: it computes the f-inverse functions from L*, a*, b* using the D65 reference white (X=0.95047, Y=1.0, Z=1.08883), then recovers X, Y, Z through the piecewise function.
Converting LAB to RGB
Use LAB to XYZ as an intermediate step to convert LAB values to RGB.
Color science calculations
Convert LAB measurements to XYZ for use in color appearance models.
ICC profile workflows
Convert between color spaces in ICC color management pipelines.
Cross-space color comparison
Convert LAB values to XYZ to compare with measurements in the XYZ space.
Enter L*, a*, b* values
Type the LAB components (L* 0-100, a* and b* typically -128 to 127).
View the XYZ values
The tool shows the X, Y, Z components.
Copy the result
Copy the XYZ values.
L* is lightness (0-100). a* is the green-red axis. b* is the blue-yellow axis.
The D65 white point is the standard for sRGB and most modern color work.
XYZ values are typically in the range 0-1 for normalized data.
Combine with an XYZ to RGB converter for a full LAB to RGB pipeline.
What is LAB?
CIELAB (L*a*b*) is a perceptually uniform color space where L* is lightness, a* is the green-red axis, and b* is the blue-yellow axis.
What is XYZ?
CIE XYZ is a device-independent color space based on human cone responses. It serves as an intermediate for conversions between other color spaces.
Is my data sent to a server?
No. All conversion happens in your browser. Nothing is transmitted.
What illuminant is used?
D65, which is the standard illuminant for sRGB and most modern color science.
Can I convert XYZ to RGB?
Yes. Use an XYZ to RGB converter as the next step in the conversion pipeline.
