In simple English
This tool puts your artwork onto blank product photos like t-shirts and hoodies. You draw a colored box on your template image to show where the art goes. The tool finds that box and fills it with every design you have. It saves hours of manual work in graphic editor programs. It costs nothing to use, and runs right on your own computer.
What it is
A Python package and command-line tool that automates product mockup creation. It scans template images for colored placeholder boxes and blends your design files into them in batches.
What it is good for
Print-on-demand sellers, e-commerce store owners, and marketing teams who need to generate hundreds of product variants without editing each image by hand.
- Processes multiple designs and mockup templates in fast parallel batches.
- Detects angled and rotated placeholder boxes automatically.
- Supports output in PNG, JPEG, and WebP formats.
- Requires Python installed on your computer and comfort with the command line.
- Needs careful color selection for placeholder boxes so the detector does not get confused.
- Lacks a graphical user interface, so all adjustments happen through text commands.
