How to extract colors from a WebP

Extracting colors from a WebP with this tool means loading one image, reviewing the detected palette ranked by how often each color appears, and exporting it in the format you need, all in the browser with no upload. For animated WebP, you can analyze a selected frame.

Beyond a quick glance at dominant colors, this tool produces a real palette you can hand off to design and front-end work. You can copy HEX codes, generate a block of CSS custom properties, or export structured JSON for use in tooling and build pipelines.

  • Open a still or animated WebP in the browser
  • For animated WebP, pick the frame to analyze
  • Review colors sorted by frequency
  • Copy HEX, or export CSS variables or JSON

Why this beats a simple color summary

A simple list of dominant colors is enough for a quick visual check, but real handoff work needs an actual palette export. That is why this tool exports HEX, CSS variables, and JSON directly rather than just showing swatches.

Sorting the palette by frequency also tells you which colors define the image versus which appear only at the edges, which helps when you are building a theme, matching brand colors, or documenting an asset.

Tips

Getting a better result out of WebP Palette Extractor

Specific settings and thresholds, not general advice.

  • This is an exact frequency count, not a quantization. Every distinct RGBA value in the frame is tallied and sorted by how many pixels use it, and the percentage shown is that color's real share of the image to one decimal place.
  • Because the count is exact, a photographic WebP can contain tens of thousands of unique colors and the top 256 will be a slice of a smooth gradient rather than a design palette. The tool is at its most useful on flat artwork, UI screenshots, icons, and charts.
  • On a logo, the top entries are often edge blends rather than brand colors, because antialiasing generates a long tail of near-duplicates. The high-percentage entries are the real fills. Anything sitting at a fraction of a percent is almost certainly an edge pixel.
  • You can cap the list at 64, 128, or 256 entries, or take all of them. The cap keeps the top by pixel count, so it never silently drops a major color, only the long tail.
  • For an animated WebP, each frame is decoded separately and the palette is per-frame. That is the way to catch a frame whose colors drifted, for example a compression pass that shifted one frame's background by a few levels.
Limits

What WebP Palette Extractor does not do

The honest boundary, so you do not lose time finding it yourself.

  • WebP input only, still or animated.
  • It counts exact RGBA values. It does not cluster perceptually similar colors into one entry.
  • There is no color-name, contrast-ratio, or accessibility analysis attached to the entries.
  • It reads the image and never modifies or re-encodes your WebP file.

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

Is the WebP palette extractor free?

Yes. The WebP Palette Extractor is completely free and runs in your browser with no sign-up or upload.

Does it stay local?

Yes. Palette extraction and export happen entirely in your browser, so your WebP file stays on your device and is never uploaded.

Can I export CSS variables directly?

Yes. The tool prepares a CSS custom-property export you can paste straight into front-end code, alongside HEX and JSON options.

Can I inspect a specific animation frame?

Yes. For an animated WebP, you can choose a frame and extract the palette from that specific frame.

Does it work on mobile?

Yes. The extractor runs in the browser, so you can pull a WebP palette on a phone or tablet with the file staying on your device.

Why does my palette have hundreds of near-identical colors?

Because the extraction counts exact RGBA values, and antialiasing, gradients, and lossy compression all generate long tails of near-duplicates. A logo with soft edges genuinely contains hundreds of blend colors. Look at the percentage column: the entries carrying real weight are the fills, and everything at a fraction of a percent is edge noise.

Can I extract the palette from one frame of an animation?

Yes. Animated WebP files are detected from the file header and decoded frame by frame, and the frame selector lets you count colors in any single frame. Palettes can differ between frames after a lossy encode, which is exactly the kind of drift this makes visible.

What formats can I export the palette in?

Three. A plain text list of hex values, one per line, for pasting anywhere. A CSS file of custom properties, ready to drop into a stylesheet. And a JSON file that keeps the pixel count, the percentage, and the alpha value for each entry, which is the one to use if you are feeding the palette into a script.

Is this the same as the dominant colors in the image analyzer?

No, and the difference matters. The analyzer quantizes the image into a small set of representative colors, which is what you want for a mood board. This counts exact values with no clustering, which is what you want when you need the literal hex codes that are actually in the file.

Does the WebP get uploaded?

No. The file is decoded in the page and every pixel is counted on your device, so an unreleased asset stays local. The only network call is a credit counter carrying the tool name.
