# Introduction

# Image Transformations

Transform your images on-the-fly using our powerful transformation system. This guide explains how to use transformations to resize, crop, filter, and optimize your images.

## URL Format

Transformations are applied by adding them to the URL:

```
https://cdn.apexxcloud.com/f/{access_id}/{transformations}/path
```

For example:

```
https://cdn.apexxcloud.com/f/abc123/tr-w_500,h_300/images/photo.jpg
```

## Basic Format

Transformations follow a simple, consistent pattern:

```
tr-{parameter_name}_{value}
```

### Combining Transformations

Multiple parameters can be combined using commas:

```
tr-w_200,h_100
```

Multiple transformation sets can be chained using plus signs:

```
tr-w_200,h_100+g_face,c_crop
```

## Transformation Categories

Our transformation system is organized into five main categories:

1. **[Resize](/transformations/image/resize)** - Control image dimensions and scaling

2. **[Crop](/transformations/image/crop)** - Smart cropping and focal point control

3. **[Effects](/transformations/image/effects)** - Visual effects and styling

4. **[Overlays](/transformations/image/overlays)** - Text and image additions

5. **[Optimization](/transformations/image/optimization)** - Format and quality controls
