Base64
A way to encode binary data as plain ASCII text.
What is Base64?
Base64 is an encoding scheme that represents binary data using a set of 64 printable ASCII characters, letting binary content travel safely through text-only channels. It is commonly used to embed images in HTML or CSS, send attachments in email, and store binary values in JSON or URLs. Base64 is not encryption; it only changes the format and increases size by roughly a third.
