Lumine tool · runs in your browser
Chat Mosaic
Turn an image or video into a colored Minecraft Bedrock chat animation. Nothing is uploaded—the browser reads the file, maps each pixel to the closest Bedrock chat color, and creates an importable Lumine settings file.
01 · Source
Choose your media
Images become one frame. Videos are sampled at the frame rate you choose.
The selected file stays on this device. It is decoded with the browser's image/video APIs and is never sent to Lumine.
02 · Shape
Tune the chat canvas
The other dimension follows the source ratio automatically.

Chat rows / frame

Blank rows appended with me\n§ſ after each frame.
Default is 30 fps, matching the proxy's original chat animation timing.
Use /.mosaic in Bedrock after importing the settings.
Bedrock palette matching
Every pixel is matched against the exact RGB foreground colors documented by the Minecraft Wiki, including Bedrock's material colors.

Build an import file
Export alias-only settings, or append the generated alias stack to an existing Lumine settings JSON.
The tool refuses to start a conversion when its conservative output estimate is above the browser import budget.
A note about Bedrock compatibility
Chat Mosaic uses Bedrock's section-sign colors. The classic colors are joined by Bedrock material colors such as Minecoin Gold, Quartz, Emerald, Diamond, Amethyst, Resin, and Light Blue. Java Edition does not interpret every one of those codes the same way.
Palette reference: Minecraft Wiki · Formatting codes. The row timing and alias format follow Lumine's original chat animation module.
