+# 🖼️ Image Resizer (GUI)
+
+A **lightweight Python desktop app** to resize images (JPG/PNG/BMP/GIF) with ease.
+Built using **Tkinter** for GUI and **Pillow** for image processing.
+
+---
+
+## ✨ Features
+
+- 📂 Select one or more images.
+- 📏 Resize by **custom width & height** (in pixels).
+- ➗ Resize by **percentage scale** (e.g., 50%).
+- 💾 Save resized images in an **output folder** with `_resized` suffix.
+- ⚡ Lightweight, dependency-minimal, and beginner-friendly.
+- 🌑 Modern dark-themed interface.
+
+---
+
+## 📂 Project Structure
+
+```
+image_resizer/
+│── app.py           # Full application (GUI + logic)
+└── output/          # Resized images are saved here
+```
+
+---
+
+## 🛠️ Requirements
+
+- Python 3.8+
+- [Pillow](https://pypi.org/project/pillow/) (PIL fork, for image processing)
+
+Install dependency:
+
+```bash
+pip install pillow
+```
+
+---
+
+## 📖 Usage
+
+1. Click **“📂 Select Images”** → choose one or more images.
+2. Enter either:
+
+   - **Width + Height** (pixels), or
+   - **Scale (%)** (e.g., 50 = half size).
+
+3. (Optional) Choose a custom output folder.
+4. Click **“⚡ Resize”** → resized images will be saved with `_resized` suffix.
+
+---
+
+## 🖼️ Supported Formats
+
+- JPG
+- PNG
+- BMP
+- GIF
