Supported image formats
Guide
Edit on GitHub ✎
If you have the GD library (available at Gd) you will also be able to create and manipulate images.
Setup
Required
If you have the GD library (available at Gd) you will also be able to create and manipulate images.
The format of images you are able to manipulate depend on the version of GD you install, and any other libraries GD might need to access those image formats.
Note
libgd-2.1.0 or higher is required. Alternatively, use the bundled GD library that ships with PHP.
Note
The GD library requires zlib >= 1.2.0.4.
You may wish to enhance GD to handle more image formats.
| Image format | Library to download | Notes |

jpeg | Jpeg | When building the jpeg library (prior to building PHP) you must use the --enable-shared option in the configure step. If you do not, you will receive an error saying libjpeg.(a|so) not found when you get to the configure step of building PHP. |
png | Libpng | |
xpm | Libxpm | It's likely you have this library already available, if your system has an installed X-Environment. |

You may wish to enhance GD to deal with different fonts. The FreeType 2 library is supported.
