@freddyaboulton I tested this with a modified version of the repro in the original issue and not sure its working with me. Here's what I tried:

import gradio as gr

def img_test(img):
    return img

with gr.Blocks() as demo:
    image1 = gr.Image(format="png", type="filepath")
    btn = gr.Button(value="process")
    btn.click(fn=img_test,inputs=[image1],outputs=[image1],api_name="process")

_, url, _ = demo.launch()

from gradio_client import Client, file

client = Client(url)
result = client.predict(
        img=file('https://raw.githubusercontent.com/gradio-app/gradio/main/test/test_files/bus.png'),
        api_name="/process"
)
print(result)

I still got a .webp image:

@abidlabs should be fixed now! Was an issue with the url case
