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?
This seems to be a Javascript thing, not a Lemmy thing. IIRC, everything that’s pasted triggers the
onpaste
event with a “image.png” file/blob, regardless of the source format.
