Questions

Is Base64 encryption?
No. It is an encoding, and anyone can reverse it in a second. It exists to move binary data through channels that only carry text.
Is it safe to paste a secret here?
The encoding runs in your browser and nothing is sent anywhere, so the page itself is safe. Whether the result is safe to paste elsewhere is a different question.
What about URL-safe Base64?
Switch the alphabet with the control below. It swaps + and / for - and _ and drops the padding.
