How It Works
Upload Image
Drop or select any PNG, JPG, or WebP image.
Extract Colors
Dominant colors are detected using pixel analysis, all in your browser.
Copy & Download
Click any color value to copy it, or download the full palette as PNG.
Extract color palettes from images online to find dominant colors for branding, web design, or moodboards. ConverterUp's color palette tool analyzes any uploaded photo and returns the most representative colors with HEX, RGB, and HSL values ready to copy. Designers can build a swatch from a product photo, illustrators can sample from reference art, and developers can pull theme colors from a screenshot. The image is processed entirely in the browser using a quantization algorithm, so private screenshots and unreleased artwork never get uploaded to a remote service.
How color palette extraction works
The extractor runs a median-cut quantization algorithm on the image's pixels. It downsamples the photo into a manageable color space, recursively splits the most varied color buckets in half, then returns the centroid of each final bucket as a representative color. The result emphasizes coverage rather than vibrancy — large muted regions (sky, walls, skin) tend to rank above small saturated accents.
If you want vivid colors instead of dominant ones, increase the palette size to 10–12 colors and ignore the first two or three entries. Alternatively, crop the image to a region that emphasizes the colors you actually want before extracting.
Every pixel is processed locally in your browser through a Web Worker, so the algorithm runs without blocking the page and the image never reaches a remote server. That matters when you are sampling unreleased product photos, internal mockups, or screenshots with sensitive content.

Use cases: branding, UI themes, moodboards
Brand discovery: drop a hero photo, screenshot of a competitor's homepage, or product render and pull the colors that drive the visual identity. Copy the HEX values straight into a Figma styles panel or a Tailwind config.
UI theming from a screenshot: developers can pick a primary, secondary, and accent color from any mockup with a few clicks instead of pixel-peeping with the eyedropper.
Moodboards and editorial design: photographers and illustrators can build cohesive palettes from a reference image, then export the swatch for use in InDesign, Photoshop, or Procreate.
Accessibility checks: pair extracted colors with a contrast checker before locking them into a design system. A palette that looks good on a hero image often fails WCAG when used as text on a light background.

HEX, RGB, HSL — which color format to copy
HEX (#2DD4BF) is the most compact and universal — CSS, design tools, brand guidelines, and Tailwind all accept hex. It is the default when in doubt.
RGB (rgb(45, 212, 191)) is preferred when you need to expose an alpha channel via rgba(), or when working with image-processing libraries that operate on 0–255 channels directly.
HSL (hsl(172, 66 %, 50 %)) describes color in human terms — hue, saturation, lightness — making it the easiest format to edit. Shift hue by 30° for an analogous color, drop lightness by 10 % for a darker shade, all without leaving the format.

Frequently asked questions
How does the tool pick the dominant colors?
It uses a median cut quantization algorithm that groups similar pixels into clusters and returns the centroid of each cluster. The result emphasizes coverage rather than vibrancy, so muted backgrounds may rank above accent colors.
How many colors does it return?
By default the palette includes the top six colors. You can adjust the count between three and twelve depending on whether you want a tight brand swatch or a richer mood palette.
Can I extract a palette from a URL or screenshot?
Yes. Paste an image directly from your clipboard with Ctrl+V (or Cmd+V) — useful when grabbing a screenshot. Remote URLs need to be downloaded first because of browser cross-origin restrictions.
Can I export the palette to Figma or Tailwind?
Yes. Click Export and choose JSON, CSS variables, Tailwind config, or an Adobe .ase swatch. The exported file lists each color with its HEX, RGB, and HSL representation so you can drop it straight into your design system.
Are my images sent anywhere?
No. The image is decoded by the browser, downsampled in memory, and analyzed locally in a Web Worker. ConverterUp never receives the file or the resulting palette.
Which image formats can I analyze?
PNG, JPG/JPEG, WebP, AVIF, GIF, and BMP. For best results use a clean image without heavy watermarks, since text overlays and logos can be picked up as their own color cluster.
