Removing EXIF tags from a PNG file

Use the exiftool Perl application.

Install on MacOS using Macports. Search using port search exiftool. The package should be named similar to p5.26-image-exiftool depending on the version of Perl you have installed.

To delete all meta information:

$ exiftool -all= ${FILENAME}

For more information, see the ExifTool documentation.
