What is a Base64 to Image Converter?

A Base64 to Image converter is an online solution that helps you decode Base64 strings back into their original image format. Base64 is a method of encoding binary data (such as images, files) into ASCII text strings, widely used in web development, APIs, email, and other applications. This tool helps you easily restore images from encoded data, serving various purposes from development to data analysis.
