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?
What OS are you using? Perhaps it’s being converted because of limitations of the clipboard?
Linux Mint Cinnamon.
Surely all clipboards pass any file without touching the insides? That’s the only easy way to make a clipboard.
