I Built a Free Color Palette Extractor That Never Uploads Your Images

说明与用途

一个完全在浏览器中运行的颜色调色板提取工具，实时返回主导颜色的 HEX、RGB 和 HSL 值，无需上传图像。

问题

Designers and developers often need to extract color schemes from images but hesitate to upload sensitive assets to external services.

结果

Instant, privacy‑preserving extraction of dominant color palettes from any image, enabling designers to quickly obtain usable hex codes without external uploads.

工作流

• Open the Color Palette Extractor on SamToolkit
• Drag or drop an image (PNG, JPG, WebP) into the interface
• The tool decodes the image, buckets similar colors, and sorts by frequency
• View the preview swatch strip
• Copy the desired hex codes with one click
• Paste the codes directly into CSS or design files

证据

Every tool on SamToolkit runs entirely in your browser using Blazor WebAssembly — nothing you upload ever touches a server.

Drop in any image — a photo, a mockup, a brand logo — and the tool analyzes the pixel data locally and returns a ready‑to‑use palette
