ExifReader is a JavaScript library that parses image files and extracts metadata such as Exif, IPTC, XMP, ICC, and MPF tags, plus embedded thumbnails. It works in both the browser and Node and supports JPEG, JPEG XL, TIFF, PNG, HEIC, AVIF, WebP, and GIF formats.
Use cases
- read exif data from jpeg photos in the browser
- extract gps coordinates from image files
- get photo date taken from heic images
- extract embedded thumbnail from a jpeg
- parse xmp metadata from png files
- read image metadata in node.js
- strip or inspect camera metadata before upload
When to choose
- you need lightweight, configurable metadata parsing across many image formats
- you want to read only metadata bytes for fast, low-bandwidth processing
- you need a library usable in browser, Node, and bundlers (ESM, AMD, CommonJS)
When to avoid
- you need to write or edit Exif metadata, not just read it
- you need full Photoshop tag or complete MakerNote support
- you work with raw camera formats like CR2 or NEF
