01 — How to use it

Text in another representation.

  1. Paste text or standard Base64.
  2. Choose encode or decode.
  3. Apply and copy the UTF-8 result.
02 — A few useful details

Base64 is an encoding, not encryption. Standard + and / symbols are supported; Base64url is not. Decoding rejects binary data that is not valid UTF-8. The result must fit the 1 MB limit.

Use UTF-8 plain text, up to 1 MB and 20,000 lines per input.
