Vintage Filter

Give your photos a warm aged look with lifted reds, muted blues, soft grain, and a gentle vignette — like a well-kept print from decades ago.

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.

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.
