About this tool
Base64 encodes data using 64 printable characters, which makes it safe to embed binary content inside text formats — for example data URLs, JSON payloads and email attachments.
This tool encodes text to Base64 and decodes it back, with correct UTF-8 handling so accents and emoji survive the round trip. Everything happens in your browser, so your data is never uploaded.
