No login required for first 1000 images. Should be enough for you. If not, contact me and I'll add more for free.
Why Choose Our LCH Extractor?
Professional-grade image processing directly in your browser. Perceptual color separation for advanced design workflows.
Advanced Color Control
Extract Luminance, Chroma, and Hue based on CIELCH(ab). This model is a cylindrical transformation of CIELAB, making it more intuitive for humans to work with color intensity and hue separately.
100% Private
Processing happens entirely in your browser. Your images never leave your computer.
Batch Processing
Process multiple images at once and download them as a single ZIP file.
Intuitive Analysis
RGB pixels are transformed into the CIELAB color space.
AB coordinates are converted to polar form (Chroma and Hue).
Individual L, C, or H components are isolated for analysis.
Frequently Asked Questions
Common questions about LCH channel extraction
What is LCH color space?
LCH (Luminance, Chroma, Hue) is a cylindrical transformation of the CIELAB color space. It is more intuitive for humans because it separates color into brightness, intensity, and hue.
Why use LCH instead of RGB?
RGB is hardware-oriented, while LCH is human-oriented. LCH allows for more precise and perceptually uniform color adjustments, which is critical for professional design and accessibility.
Is the extraction accurate?
Yes, our tool uses standard mathematical formulas for RGB to CIELAB and then to LCH conversion, ensuring high precision in channel separation.
Can I download all channels at once?
Yes, the batch processing feature allows you to extract channels from multiple images and download them as a single ZIP file.
