How to shift chroma in an image?

Select your file and set the chroma offset value — positive values increase color intensity, negative values reduce it.

What does Chroma Offset do?

It shifts the chroma (color intensity) of every pixel in OkLab color space without changing hue or lightness.

How is Chroma Offset different from Saturation Adjust?

Chroma Offset applies a flat additive shift in OkLab; Saturation Adjust multiplies existing chroma values proportionally.

What file formats can I export?

You can export as PNG, JPEG, WebP, TIFF, BMP, or HEIC.

Is this tool free to use?

Yes — completely free, no account needed. Your images are processed entirely in your browser and never uploaded to a server. Downloads have no watermarks.

Applies a uniform chroma shift in the OkLab color space to adjust color intensity without changing hue or luminance. This produces perceptually consistent saturation changes, avoiding the artifacts common in RGB or HSV-based adjustments.

Saturation Adjust

Increase or decrease image saturation online. Perfect for vivid enhancements or muted artistic looks.

Vibrancy

The Vibrancy Effect tool adaptively boosts color saturation while preserving natural-looking tones. Unlike traditional saturation adjustments that uniformly increase chroma across all colors, vibrancy intelligently applies stronger boosts to less saturated colors and milder adjustments to already vivid colors, resulting in more balanced and visually appealing results.

Warmth Adjust

Warmth adjusts the color temperature of your image to make it feel cooler or warmer by simulating different lighting conditions. Slide right for golden, cozy tones and left for cooler, crisper tones—while keeping neutrals and skin tones balanced.

Kelvin Tuner

Adjust the color temperature of your image by setting a specific white point in Kelvin. Perfect for correcting color casts from different lighting conditions or creating a warmer/cooler aesthetic. D50 is our default, you can adjust from there.

Shadow Tint

This tool applies a selective chroma shift to shadow areas of an image, allowing you to add color offset (shifts in red and blue channels) specifically to the darker regions. Use it to create stylized color grading effects or enhance shadow details with custom color adjustments while preserving the highlights and midtones.
