What's these tags names?

[Alyssa]

Hello
I am trying to modify a couple of tags in a PNG file, but I can't figure out the names


I tried with"metadatadate" and "modifydate" but with no success.

I already saw the PNG tags page:
http://www.exiftool.org/TagNames/PNG.html

But those two aren't even on the list...?

Run the command with -G0 or -G0:1, this will show you in which group the tags are located. DocumentID for instance is an XMP tag, not a PNG tag (you can have XMP embedded in a PNG file).

Hope this helps,
Hayo
