Encode plain text, UTF-8 strings, and images into Base64 format, or decode Base64 back into its original data.
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation. It is ubiquitous on the internet for embedding small images directly into HTML/CSS files, sending email attachments (MIME), and transmitting binary payloads over JSON APIs.
Our tool uses full UTF-8 byte mapping, meaning international characters, Polish accents (ą, ę, ś, ć), and modern emojis will never become garbled or corrupt.
