Sample files (numbers in parentheses show how many files per extension contain Exif metadata out of the total):
This page hosts a formal specification of Exchangeable image file format (Exif) using Kaitai Struct. This specification can be automatically translated into a variety of programming languages to get a parsing library.
All JavaScript code generated by Kaitai Struct depends on the Kaitai Struct runtime library for JavaScript. You must add this dependency to your project before you can parse or serialize any data.
The JavaScript runtime library is available at npm:
npm install kaitai-structSee the usage examples in the JavaScript notes.
Parse structure from an ArrayBuffer:
var arrayBuffer = ...;
var data = new Exif(new KaitaiStream(arrayBuffer));
After that, one can get various attributes from the structure by accessing fields or properties like:
data.endianness // => get endianness
// This is a generated file! Please edit source .ksy file and use kaitai-struct-compiler to rebuild
(function (root, factory) {
if (typeof define === 'function' && define.amd) {
define(['exports', 'kaitai-struct/KaitaiStream'], factory);
} else if (typeof exports === 'object' && exports !== null && typeof exports.nodeType !== 'number') {
factory(exports, require('kaitai-struct/KaitaiStream'));
} else {
factory(root.Exif || (root.Exif = {}), root.KaitaiStream);
}
})(typeof self !== 'undefined' ? self : this, function (Exif_, KaitaiStream) {

/**
* According to the core Exif standard, this should be ASCII, but in
* practice, this is not always the case. From
* [ExifTool FAQ](https://exiftool.sourceforge.net/faq.html#Q10):
*
* > However, it is not uncommon for applications to write UTF-8 or
* other encodings where ASCII is expected.
*
* Therefore, this field is a byte array, not a string. This is to
* avoid non-ASCII characters being treated as errors in some target
* languages, such as Python. The only assumption is that a null byte
* terminates the value (although sometimes the null byte is missing,
* which we tolerate thanks to the `eos-error: false` setting).
*
* Here is a sample JPEG file with a `tag::image_description` IFD
* field of type `field_type::ascii` that actually contains UTF-8:
* <https://github.com/Exiv2/exiv2/blob/2cd987a731236037b6b78cbff897d08685a8ef49/test/data/exiv2-bug501.jpg>
*
* It seems that most modern applications (e.g. GIMP 3.0.6) always
* use UTF-8 when storing Exif metadata. However, there are also
* files with a non-UTF-8 encoding, for example
* <https://github.com/drewnoakes/metadata-extractor-images/blob/651ad0e67aa8d43d358ad05f9bc07b52d8b9ac6e/jpg/Ricoh%20DC-3Z%20(low%20res).jpg>
* has a `tag::copyright` IFD field with a value encoded in
* ISO-8859-1 (Latin-1).
