Subset of the OpenGL API for embedded systems

OpenGL for Embedded Systems (OpenGL ES or GLES) is a subset of the OpenGL computer graphics rendering application programming interface (API) for rendering 2D and 3D computer graphics such as those used by video games, typically hardware accelerated using a graphics processing unit (GPU). It is designed for embedded systems like smartphones, tablet computers, video game consoles and PDAs. OpenGL ES is the "most widely deployed 3D graphics API in history".

Several versions of the OpenGL ES specification now exist. OpenGL ES 1.0 is drawn up against the OpenGL 1.3 specification, OpenGL ES 1.1 is defined relative to the OpenGL 1.5 specification and OpenGL ES 2.0 is defined relative to the OpenGL 2.0 specification. This means that, for example, an application written for OpenGL ES 1.0 should be easily portable to the desktop OpenGL 1.3; as the OpenGL ES is a stripped down version of the API, the reverse may or may not be true, depending on the particular features used. OpenGL ES comes with its own version of shading language (OpenGL ES SL), which is different from OpenGL SL. Version 1.0 and 1.1 both have common (CM) and common lite (CL) profiles, the difference being that the common lite profile only supports fixed point instead of floating point data type support, whereas common supports both.

OpenGL ES 1.1 added features such as mandatory support for multitexture, better multitexture support (including combiners and dot product texture operations), automatic mipmap generation, vertex buffer objects, state queries, user clip planes, and greater control over point rendering. Actual Version is 1.1.12.

The OpenGL ES 3.2 specification was publicly released in August 2015. New capabilities in OpenGL ES 3.2 include:
Geometry and tessellation shaders to efficiently process complex scenes on the GPU. Floating point render targets for increased flexibility in higher precision compute operations. ASTC compression to reduce the memory footprint and bandwidth used to process textures. Enhanced blending for sophisticated compositing and handling of multiple color attachments. Advanced texture targets such as texture buffers, multisample 2D array and cube map arrays. Debug and robustness features for easier code development and secure execution. Actual State is 3.2.6 July 2019.

Some more extensions are developed or in Development in Mesa for next OpenGL ES Version (see Mesamatrix). Next generation API is Vulkan.

Android Extension Pack (AEP) is a set of OpenGL ES 3.1 extensions, all bundled into a single extension introduced by Google in 2014. This allows applications to use all of the features of the set of extensions, while only testing for the presence of a single one. The AEP was officially added to Android Lollipop to provide extra features like tessellation over what was officially in the GLES 3.1 revision. OpenGL ES 3.2 update is largely made up of the AEP additions, which are already present in desktop OpenGL.

OpenGL ES (and OpenGL) is deprecated in Apple's operating systems, but still works in up to at least iOS 12.

There is currently no plan for a new core version of OpenGL ES, as adoption of Vulkan has been deemed to displace it in embedded and mobile applications. Development of extensions to OpenGL ES continues as of 2017.
