Base64 encode & decode
Encode plain text to Base64 or decode Base64 back to UTF-8. Whitespace in the input is ignored when decoding.
What Base64 is
Base64 maps binary data to ASCII characters so it can travel through text-only channels. It is encoding, not encryption — anyone can decode it.
When teams use it
You will see Base64 in data URLs, email attachments (MIME), some JWT segments, and quick binary-to-text hacks in scripts. Prefer HTTPS and proper secrets management for anything sensitive.
