How to adjust color temperature with Kelvin?

Select your file, enter a color temperature in Kelvin to set the white point — lower values are warmer, higher values are cooler.

What does Kelvin Tuner do?

It sets the white point to a specific color temperature in Kelvin — lower values give a warm amber tone; higher values give a cool blue cast.

Is this the same as Lightroom's Temperature slider in Kelvin mode?

Yes — both set white balance using a Kelvin value. Lower values add warm amber tones; higher values add cool blue tones, matching Lightroom's color temperature behavior.

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.

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.

Chroma Offset

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.

sRGB

Convert to sRGB

This tool takes an image that you has and converts it to sRGB. It does it by using the ICC sRGB color profile and changing the colors of your image accordingly.
