Hi @heloisedarves,
It seems that issues with image quality can come from various reasons. I’ve noted that some of your images are named ‘xx-xxx-scaled’. In case you were doing the compression of the images, this may cause a different result on WordPress and your personal machine/system. A few other reasons can cause this issue, which we can dive into in case the files themselves are not the root cause of medium image quality.
Would you be open to sharing how large are original image files on your system (both resolution and file size)? Or if easier feel free to share the link to the original images.
