Base64 in one minute
Base64 turns binary data into ASCII text using a 64-character alphabet. It is common in data URLs, email, and tokens. It is encoding for transport—not encryption.
Encode and decode safely
Use the Base64 tool on Odin to convert strings. Prefer non-production samples when debugging.
