## What it is
Exif.js is a JavaScript library for reading EXIF and IPTC metadata from JPEG and TIFF images in the browser. It works with image elements or file inputs and exposes metadata like camera make, model, orientation, and capture date via a simple callback API.

## Use cases
- read exif metadata from photos in the browser
- get camera make and model from uploaded images
- extract image orientation before displaying photos
- read the date a photo was taken from a jpeg
- parse iptc metadata from image files
- extract exif data from a file input selection

## When to choose
- you need to read EXIF or IPTC tags from JPEG/TIFF images client-side
- you want a small dependency-free browser library for photo metadata
- you need image orientation info before rendering uploads

## When to avoid
- you need to read metadata from PNG, HEIC, or other non-EXIF formats
- you need to write or strip EXIF data rather than read it
- you need a Node.js-only server-side metadata parser with active modern maintenance

## Facets
- artifact type: library
- maturity: maintenance
- function: image-processing, parser
- domain: image-processing, web-development, photography, files
- platform: browser
