**Notes for exif-js users**
If you come here from the popular but now dead exif-js package, please let me
know if you're missing anything from it and I will try to help you. Some notes:
- Questions, bug reports, suggestions, and pull requests are very much
welcome. If you've been using another Exif package you probably have some
good insights on what's missing in this one.
- ExifReader has a different API, hopefully better. :-)
- XMP support in exif-js does not seem perfect. ExifReader should be a bit
better on that part.
- ExifReader works with strict mode.
- TIFF images are not supported, only JPEG. If this is important to you, [open
an issue](https://github.com/mattiasw/ExifReader/issues/new).
- exif-js accepts IMG HTML elements as input. This falls outside of the
functionality of ExifReader. If you need this I suggest looking at exif-js
source code to see how it's done for your specific case and then pass in the
resulting data into ExifReader. If many people need this I could add a more
explicit example for how to do it together with ExifReader.
- I've been maintaining this package for close to eight years now and I have
no plans to stop doing that anytime soon.

- After parsing the tags, consider deleting the MakerNote tag if you know you will load a lot of files and storing the tags. It can be really large for some manufacturers. See the examples folder to see how you can do that.
