1. What is Image Resizing?
Image resizing is the process of changing an image's width and height. It’s commonly used to make large images fit better within a web layout or to create thumbnails for faster loading pages.
How It Works
For example, resizing a 4000x3000 image to 800x600 reduces its pixel count, often lowering file size indirectly.
Benefits
- Faster display on web pages
- Improved layout fit
- Responsive design compatibility
2. What is Image Compression?
Image compression reduces the file size of an image without changing its visible dimensions. It removes unnecessary data using algorithms.
Types of Compression
- Lossless: No quality loss; ideal for graphics and icons.
- Lossy: Some quality loss; best for photos and web images.
3. Key Differences Between Image Resizer and Image Compressor
| Feature | Image Resizer | Image Compressor |

| Changes Dimensions? | Yes | No |
| Affects Quality? | Yes, when scaled improperly | Yes, depending on settings |
