Stickerfy

A small Python tool that automatically converts PNG files into classic sticker-style images for use as stickers or emojis.

Overview

Stickerfy creates clean sticker-style PNG images from existing transparent PNG files.

The script:

• removes transparent borders around images
• creates a clean sticker outline with rounded edges
• supports three border thickness options
• adds a subtle shadow effect
• processes all PNG files automatically in the same folder as the script

Features

• Automatic alpha-channel detection
• Clean rounded sticker borders
• Adjustable border thickness:
  • Thin
  • Normal
  • Thick
• Batch processing of multiple PNG files
• Transparent PNG output

Requirements

You need:

• Python 3.10 or newer
• PNG images with transparency (alpha channel)

Installation

1. Clone this repository or download the files.
2. Install the required Python packages:

python -m pip install Pillow numpy opencv-python

Usage

Place the PNG files you want to convert into the same folder as Stickerfy.py.

Open a terminal in this folder and run:

python Stickerfy.py

Stickerfy will automatically detect all PNG files in the folder, display them, and ask for the desired border thickness.
