Questions

What is Base64?

Base64 turns any data into plain letters, numbers and a few symbols, so it can travel safely in emails, URLs, JSON and HTML.

Does it support emoji and other languages?

Yes. Text is encoded as UTF-8, so emoji and every language decode back correctly.

What is URL-safe Base64?

It replaces + and / with - and _ and removes = padding, so the result can be used in links and file names.

Is Base64 encryption?

No. Anyone can decode Base64. Use it to package data, not to protect secrets.
