    So I am having a puzzle to solve. I tried solving it but I don't know the exact approach for that. If possible someone helps me to solve this.

    Puzzle link:-
    https://ibb.co/HXkxmXJ

    I tried using hex editor but couldn't find any valuable data. Then I tried opening the "png" file with Notepad++ so I found some "RDF" code in it.
    But I am clueless what is need to be done with that. I am pasting the same code in this as well. Kindly see it and let me know the approach.

    Is there any description or only the image?
    Is the image itself tho object, or the shown hexcode?
    Could you provide the shown code as a file? I'm so lazy for typing all the letters

    Your hexdata looks a bit mixed up. In the last row you can find something that could be broken JFIF-Data. There is the SOI(Start of Image)=FF D8 followed by an APP0 (JFIF tag) = FF E0. The following data for the APP0 is inconsistent.

    In the first line you have the same, if you switch the byte-order wordwise (From D8 FF to FF D8). This Data is inconsistent too.

    The middlepart seems to be displayable chars, that I'd say on the first view could be a shiftcipher or smth

    What you are talking about is some information provided in a "iTXt"-Chunk (see http://www.libpng.org/pub/png/spec/1.2/PNG-Chunks.html) there is nothing special about this. The Checksum of all chunks is ok. I'm not sure, but I think it is not the image itself, but the hexdata that is shown

    I was about to post the solution here, but then the hidden message reminded me on one level here so I've deleted it again. Is it from a challenge here?
