About the Base64 Encoder

The Base64 Encoder correctly converts Unicode text to UTF-8 bytes before encoding, avoiding the common browser error with non-Latin characters. Base64 is an encoding for transport, not encryption.

How to use the Base64 Encoder

  1. Enter the source text.
  2. Encode it as Base64.
  3. Copy the ASCII result into the intended data field.

Practical tips

  • Do not use Base64 to protect secrets; anyone can decode it.
  • Encoded output is normally larger than the original bytes.
