line 35 should be:
screenshot = Image.new('RGB', (slices[0].size[0], offset))

Hello fabtho. I based on your code and made some modification on it.

    # initiate value
    save_path = save_path + '.png' if save_path[-4::] != '.png' else save_path
    img_li = []  # to store image fragment
    offset = 0  # where to start

    # js to get height
    height = driver.execute_script('return Math.max('
                                   'document.documentElement.clientHeight, window.innerHeight);')

    # js to get the maximum scroll height
    # Ref--> https://stackoverflow.com/questions/17688595/finding-the-maximum-scroll-position-of-a-page
    max_window_height = driver.execute_script('return Math.max('
                                              'document.body.scrollHeight, '

                                              'document.documentElement.offsetHeight);')

    # looping from top to bottom, append to img list

    while offset < max_window_height:

        driver.execute_script(f'window.scrollTo(0, {offset});')
        img = Image.open(BytesIO((driver.get_screenshot_as_png())))

some changes,
small upgrade if scrolling duplicates information

Ok , i find a very good way to do it ; )

height = driver.execute_script("return document.body.scrollHeight")
driver.set_window_size(900,height+100)
driver.save_screenshot("image.png")

this work great in headless mode.

@yassinz the code you posted does not work for mobile at all. It only captures the visible area, I tried that initially.

options = webdriver.ChromeOptions()
mobile_emulation = { "deviceName": "iPhone X" }
options.add_experimental_option("mobileEmulation", mobile_emulation)

driver = webdriver.Remote(
    command_executor=constants.WEBDRIVER_HUB_URL,
    desired_capabilities=DesiredCapabilities.CHROME,
    options=options
)

This fixes the duplication for the last image.

@trojblue unfortunately, the code still does not work as intended (atleast for me).

I tried to make a screenshot of this -> https://stackoverflow.com/questions/41721734/take-screenshot-of-full-page-with-selenium-python-with-chromedriver but the problem is that it cuts a portion of the end of a page.

wrongly-cut

I am currently trying to fix it, if I manage to fix it, I will provide the fix. (But it would be awesome if someone more competent tried to fix it)

P.S - if you take a close look, you can see on the image a few pixels comming from that black footer, which indicates there should be another text in between the footer and the page (footer is cropped as well)

@alexandervlpl

For anyone else who ends up here: in Selenium 4+ there's a save_full_page_screenshot() function for this that only works with Firefox. Give it a try, but don't expect miracles. In my case the page rendered strangely. 😢
