Image size changed on upload

I try and keep image sizes below 200KB but for some reason my images are larger after uploading to For example the last image I uploaded was 181k but the uploaded image is 524KB. Is this a bug or is it supposed to happen?

This is not supposed to happen. I think it might be a side effect of when needs to strip out location and other photo metadata, and it re-compresses it and so the size might change in that case. We’ll look into doing this more losslessly because we definitely don’t want sizes increasing (or quality changing) if the image doesn’t need to be resized.
