Image Color Extractor
An image color extractor pulls the dominant colors out of any photo or picture and hands you a ready-to-use palette. Upload an image, and this free tool reads its pixels, finds the six colors that cover the most of the picture, and shows each one as a swatch with its HEX code and RGB values. Click a swatch to copy its HEX code straight into your design tool, website, or document.

How it works
Every digital image is a grid of tiny colored squares called pixels, and every pixel has a red, green, and blue value between 0 and 255. A photo of a beach, for example, is mostly made of sky-blue pixels at the top, sand-colored pixels at the bottom, and a band of sea in between. To find the dominant colors, this tool draws your image onto a hidden canvas, reads the color of thousands of sampled pixels, and counts how often each shade appears. The shades with the biggest counts win, and the top six become your palette.
Counting exact shades would not work well on its own, because a real photo rarely repeats the exact same shade twice. A blue sky might contain hundreds of slightly different blues — one pixel is (70, 130, 200), the next is (72, 131, 201) — and counting each one separately would split the sky into hundreds of tiny groups. So the tool first groups similar shades together, rounding each red, green, and blue value down to the nearest multiple of 16, which turns those near-identical blues into a single bucket. Each bucket keeps the average color of the pixels inside it, so the result is a clean, representative shade.
Before any counting starts, the tool checks that your file really is an image. It reads the first few bytes of the file — the magic bytes — and matches them against the known signatures for PNG, JPEG, GIF, BMP, and WebP. A PNG file always starts with the bytes 89 50 4E 47, a JPEG starts with FF D8 FF, a GIF starts with the letters "GIF8", a BMP starts with "BM", and a WebP file starts with "RIFF" followed by "WEBP".
The tool also shows two useful facts about your image alongside the palette: its dimensions in pixels (width by height) and its file size in kilobytes or megabytes. A large photo, say 4000 by 3000 pixels, has twelve million pixels, so the tool samples a subset of them — up to about ten thousand evenly spaced pixels — which keeps the result fast without changing the ranking. Small images are sampled in full. The percentage shown under each swatch is the share of sampled pixels that fell into that color bucket, so the six percentages together tell you how much of the picture your palette actually explains.
Once the palette appears, each swatch is a button. Clicking it copies the HEX code to your clipboard, ready to paste into a design app, a website stylesheet, or a slide deck. The RGB values are shown too, because some tools ask for red, green, and blue numbers instead of a HEX code. The two formats describe the same color: HEX #2563EB is the same as RGB (37, 99, 235).
Worked example
Take a holiday photo of a beach: a bright blue sky across the top half, a strip of turquoise sea, pale sand at the bottom, and a white beach umbrella in one corner. Upload it and press Extract colors.
Step 1: The tool reads the file, confirms the magic bytes match a JPEG, and loads the image. It reports the size — for example, 4032 by 3024 pixels and 3.4 MB.
Step 2: It draws the photo on a canvas and samples about ten thousand pixels spread evenly across the whole picture.
Step 3: Similar shades are grouped into buckets. The many slightly different sky blues fall into one bucket, the sand tones into another, and the sea greens into a third.
Step 4: The buckets are ranked by pixel count. The sky-blue bucket is biggest, at about 28% of the sampled pixels, so it becomes color number one.
Step 5: The tool shows the palette: sky blue #4A90D9 at 28%, sand #E3CFA5 at 19%, sea turquoise #3FA7A0 at 14%, white #F5F5F0 at 9%, deep blue #2C5F8A at 8%, and warm brown #8A6D4B at 6%.
Try it yourself: upload any photo with a clear sky and press Extract colors. The top swatch will be a sky blue, and clicking it copies its HEX code. That code is the exact shade you can reuse for a website header, a presentation background, or a matching paint swatch — no guessing from a color picker required.
FAQ
What is an image color extractor?
An image color extractor is a tool that reads the pixels of a photo or picture and lists the colors that appear most often in it. Instead of guessing which shades a picture uses, you get an exact palette: the top colors with their HEX codes and RGB values. Designers use it to build color schemes from photos, to match a logo color, or to pick a background shade that fits an image.
How does the extractor find the dominant colors?
The tool draws your image onto a canvas, reads the red, green, and blue value of thousands of sampled pixels, and groups very similar shades together into buckets. Each bucket is counted, and the six buckets with the most pixels become your palette, ranked from most common to least. Grouping similar shades matters, because a photo of a blue sky contains hundreds of slightly different blues, and without grouping they would each look like a separate color.
What image formats can I upload?
You can upload PNG, JPEG, GIF, BMP, and WebP images. The tool checks the first bytes of the file, called magic bytes, to confirm the format is really one of those types, rather than trusting the file name alone. If you upload a different kind of file, such as a PDF or a text file, the tool shows a friendly error message and asks you to choose an image instead.
Are my images uploaded to a server?
No. Everything happens in your own browser on your own device. Your image is read with the FileReader API, drawn on a canvas, and analyzed locally, and it is never sent to any server. That also means the tool works offline once the page has loaded, and there is no limit on how many images you can check in a row.
How do I copy a color from the palette?
Click any swatch in the palette and its HEX code is copied to your clipboard, so you can paste it straight into a design tool, a website stylesheet, or a document. Each swatch also shows its RGB values underneath, in case the tool you are pasting into needs red, green, and blue numbers instead of a HEX code. The percentage under each swatch tells you how much of the image that color covers.
