The function uses the mode as ‘wb’ (write binary). To write the data onto the file, we use the write() function in Python. We create a file named image.jpeg to store the decoded data in its original Image format.

This function takes the encoded data as a parameter. We decode the Base64 string data using the b64decode() function of the base64 module.We take the binary data and store it in a variable.In our case, the mode is ‘rb’ (read binary). The URL and Filename safe Base64 decoding is similar to the standard Base64 decoding except that it works with Base64’s URL and Filename safe Alphabet which uses hyphen (-) in place of + and underscore () in place of / character. The open() function takes two parameters-the file to be opened and the mode. We do this using the open() function in python. Then open the file which contains base64 string data for an image.

The following steps give the working of the above code to convert the base64 string to Image in Python: How does the code to convert Base64 string to Image work? Output image generated after decoding the Base64 string: Input: Base64 string data stored in file1.txt: #write the decoded data back to original format in file Once the images have reached their destination, they can be decoded back to their original format.Ĭode to convert Base64 string to Image in Python #importing base64 moduleĭecoded_data=base64.b64decode((encoded_data))

Base64 can also be used to encode the images such that they can be stored and transferred without being corrupted.

If we want to retrieve the images back from the embedded data, we can use base64 decoding. For instance, as the image data is already embedded in the document, the browser doesn’t need to make an additional web request to fetch the file.

Base64 is used to convert images into data that can be embedded within various formats such as HTML, CSS, JSON, etc.

The following points explain the need for encoding and decoding images. There are multiple reasons for converting the Base64 string to Image and vice versa. This binary data is converted into byte-sized chunks which are converted back to the original format Why Base64 encoding and decoding is required? Here the data in ASCII format is converted back to the binary data. Decoding the data is exactly the opposite of encoding. A Base64 encoded data is the one wherein the binary form of data is represented in printable ASCII string format by translating to radix-64 representation. What is the Base64 module in Python?īase64 is a module in python that is used for encoding and decoding data.

In this tutorial, we will learn how to convert Base64 string to Image in Python. There is a need to convert them back to their original format. Such characters represent Base64 string data. Have you ever wondered how Images are being stored and transferred without being corrupted? Sometimes, when we open the images in their raw format, we observe that they are encoded in strange characters.
