How to Download All Images from a Web Page in Python?

A web page can show text, images, files, and video data on the browser. For the multi-media data like files, images, and videos we generally have the source address as the attribute to the corresponding HTML tags.

Let's say there is a web page on the internet and you want to download all its images locally using Python. So how would you do that?

In this tutorial, I will walk you through the Python program that can download all the images from a web page and save them locally. Before we write the Python program let's install the libraries that we have used in this tutorial.

Required Libraries

Python requests library

In this tutorial, we have used the requests library to send HTTP GET requests to the web page and its image URLs, to get the web page as well as image data respectively. You can install the requests library for your Python environment using the following pip install command.

pip install requests

Python beautifulsoup4 library

The beautifulsoup4 library is used to parse and extract data from HTML and XML files. In this tutorial, we will be using this to get all the image tags and their source src attribute value. To install the beautifulsoup library you can run the following pip command on your terminal or command prompt.

pip install beautifulsoup4

In this tutorial, I will be downloading all the images from our homepage "techgeekbuzz.com". Now let's get started with the Python program.

How to Download All Images from a Web Page in Python?

Let's begin with importing the required  module in our script

import requests
from bs4 import BeautifulSoup

Now let's define the url and send the get request to it.

url ="https://www.techgeekbuzz.com/"

#send get request
response = requests.get(url)

#parse response text
html_page = BeautifulSoup(response.text, 'html.parser')

The get() function will send the HTTP get request to the specified url (techgeekbuzz.com in our case). BeautifulSoup(response.text, 'html.parser') function will parse the response.text data which is actually a string representation of techgeekbuzz.com HTML code.   Now let's find out all the <img> tags from the html_page/.

images = html_page.find_all("img")

The find_all("img") will return a list of all <img> tags present  in the html_page . Now let's loop over every image tag, get its src attribute value, send HTTP GET request to the src value to get the image data in bytes, and at last, write the image byte data using Python file handling .

for index, image in enumerate(images):
    image_url= image.get("src")      #img src value
    
    image_extension= image_url.split(".")[-1]       #get image extension


    #get image data
    image_bytes = requests.get(image_url).content
    
    if image_bytes:
        #write the image data
        with open(f"Image {index+1}.{image_extension}", "wb") as file:
            file.write(image_bytes)
            print(f"Downloading image {index+1}.{image_extension}")

get("src") function will get the value of img src attribute. split(".")[-1] function will get the Image extension. get(image_url).content function will send an HTTP GET request to the image_url and return the image data in bytes. open(f"Image {index+1}.{image_extension}", "wb") statement will open a new file in write binary mode. write(image_bytes) function will write the binary data of the image and save it locally. Now you can put all the above code together and execute it.

Python program to download Images from a web-page

import requests
from bs4 import BeautifulSoup

url ="https://www.techgeekbuzz.com/"

#send get request
response = requests.get(url)

html_page = BeautifulSoup(response.text, 'html.parser')

images = html_page.find_all("img")

for index, image in enumerate(images):
    image_url= image.get("src")      #img src value
    
    image_extension= image_url.split(".")[-1]       #get image extension

    #get image data
    image_bytes = requests.get(image_url).content
    
    if image_bytes:
        #write the image data
        with open(f"Image {index+1}.{image_extension}", "wb") as file:
            file.write(image_bytes)
            print(f"Downloading image {index+1}.{image_extension}")

Output

Downloading image 1.jpeg
Downloading image 2.png
Downloading image 3.png
Downloading image 4.png
Downloading image 5.png
Downloading image 6.png
Downloading image 7.png
Downloading image 8.jpg
Downloading image 9.png

When you execute the above program you will see a similar output on the terminal or output console. You can also check your directory where your Python script is located, and whether all the images downloaded on your system or not.

Conclusion

In this Python tutorial, we learned how can we download images from a web page using Python?.

In the above program, I have used the GET request two times one to get the HTML web page of the url and the second to get the image byte data from the image url. To download or save the image locally I have used the Python file handling where I have opened the file in write binary mode and wrote the image binary data in the file.
