To convert Base64 to an image, decode the Base64 string and write the resulting binary data to a file with an appropriate image format extension. This process creates a displayable image from encoded text.
Base64 encoding is commonly used in data transmission and storage for encoding binary data as text to be incorporated in media such as HTML or CSS files. The process utilizes 64 characters, including letters, numbers, and symbols, to represent binary information in a textual form.
To turn a Base64 string back into an image, the encoded data must be converted from text back to its original binary format. This decoded binary data is then saved as an image file, typically with extensions like. jpg,. png, or. gif. This transformation is integral for web developers and programmers who handle images in web applications, ensuring that images are accurately rendered after being stored or transferred as encoded text.
