ex_image_info
A fast Elixir library to parse image binaries and extract dimensions, mime-type, and validity for 13+ formats.
What is ex_image_info?
ExImageInfo is an Elixir library that parses raw image binaries to extract metadata such as dimensions (width and height), mime-type, format variant, and validity. It solves the problem of quickly and accurately identifying image properties without loading the entire image or relying on external dependencies, supporting over 13 common and modern image formats.
Elixir developers building applications that need to process, validate, or analyze images—such as content management systems, image upload services, media pipelines, or static site generators.
Developers choose ExImageInfo for its benchmarked speed, extensive format support including modern formats like AVIF and HEIC, and its dependency-free design. It returns comprehensive metadata in a single efficient pass, with careful attention to format specifications.
Overview
ExImageInfo is an Elixir library to parse images (binaries) and get the dimensions (size), detected mime-type and overall validity for a set of image formats. It is the fastest and supports multiple formats.
