+# Image Format Converter (PNG ⇆ JPEG)
+
+A simple yet powerful **Python script** that converts all **PNG files to JPEG** or **JPEG files to PNG** in a specified folder using the [Pillow](https://pypi.org/project/Pillow/) library.
+
+---
+
+## Features
+
+- Converts all images in a folder between **PNG** and **JPEG** formats  
+- Automatically skips invalid image files  
+- Saves converted images in a `converted/` subfolder (originals remain safe)  
+- Simple CLI-based input for folder path and target format  
+- Clear console messages for every step  
+
+---
+
+## How It Works
+
+1. The program scans the specified folder for image files (`.png`, `.jpg`, `.jpeg`).
+2. Based on the user’s chosen output format:
+   - Converts all **PNG → JPEG**, or  
+   - Converts all **JPEG → PNG**.
+3. Converted images are saved into a new `converted/` subfolder.
+
+---
+
+## Requirements
+
+Make sure you have **Python 3.7+** installed, then install the Pillow library:
+
+```bash
+pip install pillow
+````
+
+---
+
+## ▶️ Usage
+
+Run the script using:
+
+```bash
+python convert_images.py
+```
+
+When prompted:
+
+* Enter the folder path where your images are stored
+* Enter the desired target format (`jpeg` or `png`)
+
+**Example:**
+
+```
+Enter the folder path containing images: ./photos
+Enter target format ('jpeg' or 'png'): jpeg
+Converted: sample1.png → sample1.jpeg
+Converted: flower.png → flower.jpeg
+Conversion complete! 2 files saved to './photos/converted'
+```
+
+---
+
+## Example Folder Structure
+
+```
+photos/
+ ├── flower.png
+ ├── sky.png
+ └── convert_images.py
+```
+
+After conversion:
+
+```
+photos/
+ ├── flower.png
+ ├── sky.png
+ ├── convert_images.py
+ └── converted/
+      ├── flower.jpeg
+      └── sky.jpeg
+```
+
+---
+
+## Notes
+
+* The script does **not overwrite** original images.
+* Only `.png`, `.jpg`, and `.jpeg` formats are supported.
+* Large image folders may take longer to process.
+

+"""
+A Python utility script to convert all PNG files in a folder to JPEG, or
+all JPEG files to PNG.
+
+This script uses the Pillow (PIL) library for image processing.
+
+Features:
+- Converts all images in a folder between PNG and JPEG formats.
+- Maintains original file names (only changes extensions).
+- Handles errors gracefully (e.g., invalid image files or missing folder).
+- Creates an output subfolder named 'converted' to avoid overwriting originals.
+
+Usage:
+    python convert_images.py
