How to encode Base64

  1. Type or paste text, or choose "Encode a file…".
  2. Pick URL-safe Base64, line breaks or a data: URL if you need them.
  3. Copy or download the result.

Good to know

  • Text is encoded as UTF-8, so accents, other scripts and emoji come back exactly.
  • URL-safe Base64 uses - and _ instead of + and / and drops the = padding, as JWTs and many URLs do.
  • Base64 is about a third larger than the original data. It is an encoding, not encryption: anyone can decode it.
