+# CONVERT_JPEG_to_PNG
+
+This project contains a simply python script to change file extension from .jpeg to .png
+
+## Requirements
+Pillow module
+
+`pip install pillow`
+
+## Two methods:
+
+I accomplished this task in two ways
+### Using Terminal
+- Add the image in jpeg format with name as 'input' in this folder.
+- Run converter_terminal.py script
+- output image will be generated in this folder
+
+### Using GUI
+Just run the converter_GUI.py script and pick any jpeg image from any location and then press 'Convert Jpeg to Png'
