Questions

What is Base64 for?

Putting files or binary data where only text fits: email attachments, data URLs in HTML and CSS, JSON, and API keys or tokens. It is an encoding, not encryption, so anyone can decode it.

Which character set is used for text?

UTF-8, as on the web, so accents, other alphabets and emoji encode and decode correctly.

Is Base64 encode and decode free?

Yes, and as often as you like. It works in your browser, so there is nothing to sign up for.

What happens to my files?

They stay on your device. Everything is worked out in your browser, so nothing you type or choose is uploaded.

Do I need to install anything?

No. It works in the browser on any computer, tablet or phone.

Can I use Base64 encode and decode from my own code?

You won't need to: every programming language has hashing, Base64 and URL encoding built in. This page is for quick jobs by hand.
