Base64 encoder and decoder

About this tool

Choose encode or decode and paste your text. Text is converted as UTF-8, so umlauts and emoji survive the round trip. For use in URLs and tokens, switch to the URL-safe variant, which replaces + and / with - and _, and optionally drop the = padding.

Good to know

Base64 is an encoding, not encryption: anyone can decode it. It makes data about a third larger.
