About These Tools
All tools run entirely in your browser using JavaScript. No data is sent to any server. Images you upload for palette extraction are processed locally using the HTML5 Canvas API.
These tools are designed to help designers, developers, and artists work with color more effectively — whether you need to match colors from a photo, convert between color formats, or build a harmonious palette from scratch.
