What Base64-encode a List Tool Can Do:

  • Encode each line of input separately using Base64
  • Trim whitespace before encoding
  • Ignore empty lines in output
  • Convert to URL-safe Base64 (replaces + and /, removes = padding)
  • Import files in formats like .txt, .csv, .log, .json, and more
  • Export results and track how many lines were processed

Example:

Input:

apple
banana

Output:

YXBwbGU=
YmFuYW5h

(If URL-safe enabled: YXBwbGU and YmFuYW5h no padding)

Common Use Cases:

Useful for preparing lists of identifiers or tokens for safe transmission, encoding data for URLs or APIs, or transforming text inputs into Base64 on a per-line basis for debugging or integration purposes.

Useful Tools & Suggestions:

If you’re Base64-encoding a list, Trim List Items is a good first move it strips out extra spaces that could mess with the encoding. Once everything’s encoded, Join List Items helps flatten the output into one tidy line, perfect for APIs, storage, or sharing. That way, your list turns into a compact, clean string without any extra noise.
