# The Ultimate Guide to Image Compression in 2025

Image compression is more important than ever in 2025. With the rise of high-resolution displays and mobile-first web design, understanding how to optimize your images can make or break your website's performance.

## What is Image Compression?

Image compression is the process of reducing the file size of digital images while maintaining acceptable visual quality. There are two main types:

### Lossy Compression
- Permanently removes some image data
- Smaller file sizes
- Best for photographs (JPEG)

### Lossless Compression
- Preserves all original image data
- Larger file sizes but perfect quality
- Best for graphics and logos (PNG)

## Modern Image Formats

### JPEG
The most widely supported format, perfect for photographs with complex color gradients.

### PNG
Ideal for graphics, logos, and images requiring transparency.

### WebP
Google's modern format offering superior compression and quality.

### AVIF
Next-generation format with even better compression than WebP.

## Best Practices for 2025
