go-exif-knife: One Exif Command-Line Tool to [Nearly] Rule Them All

go-exif-knife is a tool that will allow you to parse Exif from JPEG and PNG images and to do a brute-force parse of Exif embedded in any other format. You can cherry-pick specific IFDs or tags to print, and print them both as normal and JSON-formatted text. You can can also print parsed GPS data and timestamps and even produce a Google S2 geohash from the GPS data, and dump the thumbnail. If using JPEG or PNG, you can also update or add new Exif data.

This project is built on top of go-jpeg-image-structure, go-png-image-structure, and go-exif. PNG added support for Exif only in the last year, and this project was in service of providing useful Exif support for PNG.

Binary downloads are available here.
