How to Convert and Save a Base64-Encoded Image to the Filesystem in Python?

Convert string in base64 to image and save on filesystem

Given a string in base64 format, which represents a PNG image, a common task is to need to save this image to the filesystem, as a PNG file.

Here are steps to convert a base64 string to an image and save it to the filesystem using Python:

1. Decode the base64 string to get the raw image data:

<code class="python">import base64

img_data = base64.b64decode(base64_string)</code>

2. Open a file for writing in binary mode:

<code class="python">with open("image.png", "wb") as f:</code>

3. Write the raw image data to the file:

<code class="python">    f.write(img_data)</code>

4. Close the file:

<code class="python">f.close()</code>

Here is a complete example:

<code class="python">import base64

# Replace "base64_string" with the actual base64-encoded string
base64_string = ""

img_data = base64.b64decode(base64_string)

with open("image.png", "wb") as f:
    f.write(img_data)</code>

This will save the PNG image to a file named "image.png" in the current directory.
