Frequently Asked Questions
What is a Gradient Map?
A gradient map is a creative image adjustment that remaps the tonal values of an image to the colors of a gradient. Dark areas (shadows) are mapped to one color, bright areas (highlights) to another, and midtones to intermediate colors. This technique is widely used in professional photo editing, cinematic color grading, and graphic design to create striking duo-tone and tri-tone effects.
How does this online Gradient Map tool work?
Upload your photo (or use the built-in demo image), choose a preset gradient or customize your own shadow and highlight colors, then adjust the intensity slider. The tool converts each pixel's brightness to a grayscale value and maps it to the corresponding color on your gradient. Everything is processed locally in your browser using Canvas — your images are never uploaded to any server, ensuring complete privacy.
What image formats are supported?
The tool supports all common image formats including JPG/JPEG, PNG, WebP, and AVIF. Uploaded images can be up to 20MB in size. When downloading, the result is saved as a high-quality PNG file to preserve all color detail.
Can I use more than two colors in my gradient?
Yes! Click the + button next to the color pickers to add a midtone color stop. This enables tri-tone mapping: shadows map to the first color, midtones to the second, and highlights to the third. This creates even richer, more nuanced color effects. You can remove the midtone at any time by clicking the button again.
What does the Intensity slider do?
The Intensity slider controls how strongly the gradient map blends with the original image. At 100%, the image is fully converted using the gradient map (grayscale → gradient colors). At lower values, the mapped colors blend with the original image colors, creating a subtle tint effect. This gives you fine control over the final look — from a dramatic full remap to a gentle color wash.
Are my images uploaded to a server?
No — your privacy is paramount. All image processing happens entirely within your browser using the HTML5 Canvas API. Your photos are never transmitted, stored, or processed on any remote server. You can use this tool offline after the page loads.
What's the difference between a Gradient Map and a simple color filter?
A simple color filter applies a uniform color overlay across the entire image. A gradient map, on the other hand, intelligently assigns colors based on the brightness of each pixel. This preserves the tonal structure and contrast of the original image while replacing its color palette — resulting in a much more professional, dimensional look that retains image detail.
Can I use this tool for professional photo editing?
Absolutely. Gradient mapping is a staple technique in professional workflows — from cinematic color grading (the famous teal-orange look) to fashion photography and album cover art. This tool gives you instant, high-quality results you can download and use directly in your projects. For advanced editing, you can take the output into Photoshop, Lightroom, or similar software for further refinement.
