Base64 Encode / Decode
Encode text to Base64 or decode it back, with full UTF-8 support.
About this tool
Base64 encodes binary or text data using 64 safe ASCII characters, so it can travel through systems that only handle text — data URIs, JSON fields, email and HTTP headers among them.
Switch between encode and decode, paste your input, and get the result instantly with proper UTF-8 handling so accented characters and emoji survive the round trip. It all runs in your browser.
Frequently asked questions
No — it's encoding, not encryption. Anyone can decode Base64 trivially (this tool does). Never use it to protect secrets.
