Discord doesn't strip EXIF from PNGs, only JPEGs

  Seriously? What's the reasoning behind that?

    It's rare to see PNGs in-the-wild containing EXIF data, it's a feature that's only been in the spec since ~2017. I'm actually looking for one to double-check my statement about discord, but I can't find any. Edit: I made my own. I can confirm that the exif chunk was not stripped. https://cdn.discordapp.com/attachments/541730746805649476/1086755596319064237/out_1.png https://cdn.discordapp.com/attachments/541730746805649476/10...

  That's interesting. I've seen a couple of rotated PNGs before which I assumed were caused by Discord stripping the EXIF and orientation data. Found a PNG like that without EXIF from May 2022 so I wonder if Discord stopped stripping or if it was stripped on the person's device somewhere.
