Base64 Encoder & Decoder
Encode or decode Base64 text and files, Unicode-safe.
About the Base64 Encoder & Decoder
Encode text or files to Base64 and decode Base64 strings back to text. Full Unicode support means emoji and accented characters survive the round trip. Files are read locally and never uploaded.
Frequently asked questions
Is Base64 encryption?
No. Base64 is an encoding, not encryption — anyone can decode it. Never use it to protect secrets.
Why does my Unicode text break when decoding?
It does not here — this tool encodes UTF-8 bytes, the correct approach for non-ASCII text.
