What is Base64?

Base64 is an encoding scheme that converts binary data into ASCII text using 64 characters (A–Z, a–z, 0–9, +, /). Defined in RFC 4648, it lets you embed binary (images, files) in JSON, XML, data URIs, or URLs. Base64 is not encryption. Anyone can decode it. Use it for transport or storage, not for securing data.
