OpenImageIO is a C++ library and toolset for reading, writing, and processing images in nearly any file format through a format-agnostic plugin-based API, built for VFX and animation production. It includes command-line tools like oiiotool, an image viewer, and an ImageCache for scalable texture access.

Use cases

• convert images between file formats from the command line
• read and write EXR, TIFF, PNG, and other formats in a renderer or compositor
• compare two images for differences in a render pipeline
• inspect image metadata from the terminal
• cache large texture files for film production rendering

When to choose

• building VFX, rendering, or compositing software that must handle many image formats
• you need a robust, production-proven image I/O library with a plugin architecture
• you want command-line tools for batch image conversion and inspection

When to avoid

• you only need simple web image handling in a high-level language
• your project is not C++ and bindings are not acceptable
• you need GPU-accelerated image editing rather than I/O and processing
