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?

    But why does it convert only when using copy and paste? Via download and upload, the jpeg stays jpeg.

    The converter can see it was smaller before the conversion. Why not save the smaller jpeg? Who needs pngs, no matter how wasteful?

    I’d guess Firefox takes a screenshot when I try to copy an image.
