jpeg
What is a .jpeg file?
JPEG is a lossy raster image format based on discrete cosine transform compression, identical in encoding to files using the .jpg extension. It stores 8-bit truecolor without transparency and supports both baseline and progressive scan encodings. It is the dominant format for photographic content.
How to use a .jpeg file
Use an example JPEG to exercise image libraries, metadata and color-profile extraction, and thumbnail or transcode pipelines, verifying consistent handling regardless of the .jpg or .jpeg extension.
