# How to convert an image to PVRTC format? (PVR or KTX file)

With TexturePacker's `--convert-texture` command line option you can easily convert a single image to a different format:

```bash
TexturePacker --convert-texture input.png \
              --pixel-format PVRTCII_4BPP --texture-format pvr3
```

The _pixel format_ specifies the compression algorithm to use, the _texture format_ describes the file container. The following formats are supported for PVRTC compression:

| Pixel format | Bits per pixel | Description |
| --- | ---: | :--- |
| `PVRTCI_2BPP_RGBA` | 2   | PVRTC compression, 2bit per pixel |
| `PVRTCI_4BPP_RGBA` | 4   | PVRTC compression, 4bit per pixel |
| `PVRTCI_2BPP_RGB` | 2   | PVRTC compression, 2bit per pixel, no transparency |
| `PVRTCI_4BPP_RGB` | 4   | PVRTC compression, 4bit per pixel, no transparency |
| `PVRTCII_2BPP` | 2   | PVRTC2 compression, 2bit per pixel |
| `PVRTCII_4BPP` | 4   | PVRTC2 compression, 4bit per pixel |

| Texture Format | Description |
| :--- | :--- |
| `pvr3` | PowerVR Texture Format. Native format for iOS and PowerVR GPUs. |
| `pvr3gz` | PowerVR Texture Format, compressed with gzip. Smaller on disk, decompressed at load time. |
| `pvr3ccz` | PowerVR Texture Format, compressed with zlib, cocos2d header. |
| `ktx` | Khronos Texture. Standard container for OpenGL ES textures. |
| `ktx2` | Khronos Texture (Version 2). Newer format with Basis Universal support. |
| `zktx` | Khronos Texture (gzip compressed). KTX file compressed for smaller storage. |

The [Image quality](https://www.codeandweb.com/texturepacker/documentation/texture-settings#image-quality) can be configured with `--pvr-quality <0-7>`, default value is 3.  
For other options (scaling, trimming transparency, ...) have a look at the [Image conversion](https://www.codeandweb.com/texturepacker/documentation/image-conversion) documentation.
