Imageio is a mature Python library for reading and writing image and video data, including animated images, volumetric data, and scientific formats like DICOM and TIFF. It provides a simple, consistent API (imread/imwrite/imiter) that returns NumPy arrays and supports 295+ formats across Windows, Linux, and macOS.

Use cases

• read and write images in python
• convert png to jpg
• create animated gifs from frames
• read video files with ffmpeg
• load dicom medical images
• read multi-page tiff stacks
• capture frames from a webcam
• load images as numpy arrays

When to choose

• you need a simple, unified API for reading/writing many image and video formats
• you work with scientific or volumetric imaging data like TIFF or DICOM
• you want images returned directly as NumPy arrays for use with NumPy/SciPy/scikit-image
• you need cross-platform support with minimal core dependencies

When to avoid

• you need advanced image manipulation features like filtering or transforms rather than just I/O
• you need GPU-accelerated image processing
• you are not working in Python or the NumPy ecosystem
