About Palettum
Palettum is an open-source tool for recoloring images, GIFs, and videos with a custom palette. It is available as a web app and as a command-line tool. Each pixel can be snapped to its closest palette color, which suits pixel-art styles, or the palette can be blended as a filter for a smoother effect.
The repository includes instructions for building the command-line tool with Cargo and for running the web app locally with Bun. It also describes self-hosting the web app with Docker. The README marks the examples and installation sections as unfinished. Its macOS installation instructions use Homebrew, and other systems are pointed to precompiled binaries on the releases page.
