https://github.com/discourse/discourse/commit/a9c0df0b58c5495c574286084278b00a5d283cd3 Hi, I wanted to ask about this commit. Why do pasted PNGs get converted to JPG in any case? what breaks without this commit? why is it called FIX? Thank you very much :smiley: spirobel

I am sorry, but I can not find the answer to my question in your link. My question is not why pngs get converted to jpg, my question is: why do pasted PNGs get converted to JPGs? I dont understand why there is a difference between pasted and non pasted. Thanks :smiley:

Pasted images typically come across as raw bitmaps, so saving them all as PNG (lossless) would be hugely wasteful in file size. Instead we test saving in both formats and see which results in a “reasonable” size, so (most) images end up efficiently stored as JPGs (lossy).

Thank you for your answer! I think I start to understand this now. -----------------------------149589358933568048074206291858 Content-Disposition: form-data; name="type" composer -----------------------------149589358933568048074206291858 Content-Disposition: form-data; name="files[]"; filenam…
