What is Base64?

Binary as text

Base64 turns bytes into plain ASCII text so binary data can travel through text-only systems like JSON, email, or environment variables.

When to use it

Use Base64 for small payloads, data URLs, API fixtures, certificates, tokens, or embedding file bytes in text formats. It is encoding, not encryption.
