How does it work?

Choose an action, paste your text or Base64 string and run it. Text is encoded as UTF-8, so accented characters and emoji convert correctly. You can also pick the URL-safe variant.

Frequently asked questions

Is Base64 encryption?

No. Base64 is just an encoding that anyone can reverse. Don't use it to protect sensitive data.

What is URL-safe Base64?

It uses '-' and '_' instead of '+' and '/' and drops the trailing '=' padding. JWTs and URLs use it.
