Having trouble getting transparent backgrounds in ChatGPT images

And your fox image is rendering with full alpha-channel transparency too! Well done!.. again though, GIF vs PNG, showing PNG can’t render ALPH on live surfaces… at least I haven’t seen such yet.

As for your image, it appears you’re getting an artifact from the “cutting” feature @_j and @windysoliloquy brought up earlier in the thread… I even threw some minor shade for them bringing up “cutting”, not realizing the pipeline going into it, so my bad there gentlemen … regardless, I imagine that if @_j is using the “cutting” effect for getting his transparency that exact, it’s probably just a matter of getting the “cut” on a more precise, granular level for your image…

… I do a full image conversion from PNG to WebP, so I have never encountered the “cutting” future directly, so unfortunately, I’m not much help there… you’re way ahead of the PNG game though, so a to you too!.. to those still on the PNG game aiming for transparency…

… again, get more creative about being creative …
