On a forum I help run, I decided to upload a calculator for an emoji. Upon uploading, Discourse made the transparent background solid white. Why did this occur, and is there a workaround? ▶ Image for reference

[image] Auto convert upload to JPG? Support I have noticed that some image uploads always convert to jpeg, this creates ugly situations with images with transparent elements and dark/light mode. I couldn’t find a setting for this, can we somehow turn this …

Thanks for that, I temporarily set the png to jpg quality to 100 while I uploaded the image, and it left the background intact. Restored to default now, will bookmark this for myself in the future.

When certain images are uploaded, Discourse adds a solid background to them
