World's simplest online Portable Network Graphics (PNG) to LAB color converter. Just import your PNG image in the editor on the left, and you'll get individual LAB color model components on the right. In the tool options below, you can select which individual channel to export – Lightness (L), A (green-red), and B (blue-yellow). Free, quick, and very powerful. Import a PNG – extract its LAB color model channels. Created with love by team Browserling.

This browser-based utility converts a PNG image into its LAB color components. Unlike RGB, which is based on how screens display colors using red, green, and blue light emitting diodes, LAB is designed to more closely match human vision. It consists of three components: L, A, and B. The "L" channel stands for "Lightness" and represents the brightness of each pixel, ranging from 0 (black) to 100 (white). The "A" channel represents the green-red component, with negative values indicating green and positive values indicating red. The "B" channel represents the blue-yellow component, with negative values indicating blue and positive values indicating yellow. The LAB model is particularly useful for high-end color correction and image editing, as it separates brightness from color information. The LAB color space is also sometimes referred to as L*a*b* and CIELAB. When applied to a PNG file, this tool splits the image into these three channels. Each channel can be viewed and extracted individually, or you can generate three separate images with the channels displayed side by side at once. You can also view these channels in grayscale tones to better understand the intensity distribution in them without the color information. Png-abulous!

In this example, we extract only the A channel from a PNG photo of four autumn leaves. As you can see, the leaves contain different hues – red, orange, yellow, and light green. Since the A channel maps the green-red axis of LAB color space, we can clearly observe how certain leaf regions lean toward red (pink tones) and others toward green (cyan tones). This separation reveals hidden color relationships that are not as obvious in the original PNG. (Source: Pexels.)
In this example, we convert a PNG image of colorful macaroons into "A" and "B" channels from the LAB color space. The "A" channel highlights the red and green variations in the macaroons, while the "B" channel reveals the blue and yellow components. By visualizing both channels side by side, we can analyze how chromatic components are spatially distributed in the image and contribute to the overall color palette. (Source: Pexels.)
In this example, we split a PNG image of a basket of vegetables into all three LAB channels and display them in grayscale. The Lightness (L) channel emphasizes the luminance (brightness) of each vegetable, while the A and B channels reveal the color spectrums in terms of red-green and blue-yellow content. The grayscale filter helps us focus on the relative intensity distribution within each LAB channel instead of the spatial encoding of luminance and chromaticity. (Source: Pexels.)
