What Is Base64 Image Encoding?

Base64 is a text-based encoding format that represents binary data, such as an image, using only readable ASCII characters. Developers commonly use it to embed images directly inside HTML, CSS or JSON files without linking to a separate image file.

Because Base64 strings can become long and are not human-readable as images, this converter decodes that text back into a real, viewable, and downloadable image file.
