Question 1

How do I use this?

Accepted Answer

Pick Encode or Decode in the settings, put your text in the box and press Run — the result appears below. Encode turns plain text into Base64; Decode turns Base64 back into the original text.

Question 2

What about URL-safe Base64?

Accepted Answer

This gives you standard Base64, with +, / and =. The URL-safe variant swaps + for -, / for _ and drops the trailing =. If the value is going into a URL, run the result through the URL encoder or make those swaps yourself.

Question 3

Will non-Latin characters survive?

Accepted Answer

Yes. The browser's own function only handles Latin characters, so this tool converts your text to UTF-8 bytes first and restores it the same way — accented letters, other scripts and emoji all come back intact.
