I just made a post copy-pasting images from another tab. All jpegs became pngs, for example 1.3MB became 6.4MB.
If I save the image first, then upload to Lemmy, it stays as a jpeg. What causes the pointless converting when copy-pasting? Can it be stopped from happening?

Surely all clipboards pass any file without touching the insides? That’s the only easy way to make a clipboard.
