Does IPTC editing modify picture itself ?

Postby CreativeWorld » Wed Sep 20, 2017 11:33 am

Hello all,

Question in the title. I've plenty of pictures in which i'd like to add a legend + comments. Of course i'd like the picture file itself not being modified (I know that saving jpeg, again and again, has an impact on picture quality).
For both jpeg & raw.

Thanks in advance for your help.

Editing IPTC in browser is lossless, only the header is modified
