What is WeChat Sticker Maker?
The WeChat Sticker Maker is a powerful automation utility designed to bridge the gap between creative design and technical submission requirements. Using this tool from the Openclaw Skills collection, developers and designers can take a single composite image—such as a 6-grid, 9-grid, or 12-grid layout—and instantly generate a full suite of assets compatible with the WeChat Open Platform. It handles everything from pixel-perfect resizing to the generation of required metadata files, ensuring that your sticker packs are ready for upload without manual formatting.
WeChat Sticker Maker Use Cases
- Converting character design sheets into individual WeChat stickers
- Rapidly generating thumbnails and main sticker images in bulk
- Preparing submission-ready metadata and info templates for the WeChat sticker store
- Automating background removal for raw illustrations to create transparent stickers
How WeChat Sticker Maker Works
- Provide a source grid image and define the layout configuration (e.g., 3x3).
- Run the script via the CLI, optionally enabling the AI-powered background removal feature.
- The system slices the image into discrete stickers and applies standard WeChat dimensions (240x240 for main, 50x50 for icons).
- A structured output directory is created containing all images, metadata templates, and candidate covers.
- Review the generated meta.txt and info.txt files to finalize descriptions and meaning keywords.
WeChat Sticker Maker Setup
The tool automatically manages its own environment by creating a virtual environment on the first run. Use the provided shell script for the easiest experience:
# Basic usage to process a grid image
./skills/wechat-sticker-maker/scripts/run.sh /path/to/grid_image.png
# Process with AI background removal and 3x3 layout
./skills/wechat-sticker-maker/scripts/run.sh /path/to/image.png --remove-bg --layout 3x3
# Specify a custom output directory
./skills/wechat-sticker-maker/scripts/run.sh /path/to/image.png --output ./my_stickers
