Base64 Encode / Decode
Base64, both ways.
Encode text to Base64 or decode it back — Unicode-safe, and entirely in your browser.
What is the Base64 Encode / Decode?
BYAFT's Base64 tool encodes text to Base64 and decodes it back, right in your browser. It is UTF-8 safe, so accented characters and emoji round-trip correctly — no sign-up, and nothing uploaded.
Use it to inspect a Base64 string, prepare a small data payload, or decode an encoded value while debugging.
