Fun Fact
Base64 encoding increases the size of an image by roughly 33%. While it makes images easier to transmit as text, it also makes them larger, which is why decoding back to PNG is essential for real-world usage.
Historical Context
Base64 encoding was originally developed as part of the MIME standard in the early days of email to allow binary files such as images to be safely transmitted through text-only systems. Over time, it became widely used across the web for embedding images, transferring media through APIs, and storing binary data in text formats. Tools like this decoder continue that legacy by making it easy to convert encoded data back into its original visual form.
